And yes, in principle, that\u2019s true. You can just slap a sub into a system, and it\u2019ll probably make things sound bigger. But if you actually want to integrate a subwoofer properly, there are a few things worth thinking about first.<\/p>\n<p>The obvious question is: <strong>how many subwoofers do I need?<\/strong> Annoyingly, the answer isn\u2019t just \u201cone\u201d, \u201ctwo\u201d, or \u201cas many as you can sneak into the room before someone notices\u201d. It depends on your space, your main speakers, and what you\u2019re using the system for. A compact stereo setup in a small room has very different needs to a dedicated home cinema with multiple seats.<\/p>\n<p>It\u2019s also about scale. The sub needs to make sense with the rest of the system and the room it\u2019s going in. A tiny sub won\u2019t do much for big floorstanders, and a huge sub in a tiny flat could become more of a problem than an upgrade.<\/p>\n<p>Subwoofers now come in all sorts of sizes, shapes, and finishes too, so placement and aesthetics are super important.<\/p>\n<p>So, let&#8217;s get into how many subwoofers you actually need!<\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/www.av.com\/blog\/wp-content\/uploads\/2025\/07\/AV-Trade-in-Blog-Banner.jpg&#8221; alt=&#8221;AV Trade-In In-Page Banner&#8221; title_text=&#8221;AV-Trade-in-Blog-Banner&#8221; url=&#8221;https:\/\/www.av.com\/trade-in?utm_source=blog&#038;utm_medium=banner&#038;utm_campaign=blog+av+trade+in&#8221; url_new_window=&#8221;on&#8221; admin_label=&#8221;AV Trade-In In-Page Banner&#8221; _builder_version=&#8221;4.17.4&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221; global_module=&#8221;46457&#8243; theme_builder_area=&#8221;post_content&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.18.0&#8243; _module_preset=&#8221;default&#8221; custom_padding=&#8221;20px||||false|false&#8221; hover_enabled=&#8221;0&#8243; border_width_top=&#8221;2px&#8221; border_color_top=&#8221;gcid-45928375-1fd3-4d7e-b1f0-0adee316b54f&#8221; global_colors_info=&#8221;{%22gcid-45928375-1fd3-4d7e-b1f0-0adee316b54f%22:%91%22border_color_top%22%93}&#8221; theme_builder_area=&#8221;post_content&#8221; admin_label=&#8221;Key takeaways&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Key_takeaways\"><\/span>Key takeaways<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<table id=\"tablepress-150\" class=\"tablepress tablepress-id-150\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\">Setup<\/th><th class=\"column-2\">Best for<\/th><th class=\"column-3\">Why use it?<\/th>\n<\/tr>\n<\/thead>\n<tbody class=\"row-striping row-hover\">\n<tr class=\"row-2\">\n\t<td class=\"column-1\"><strong>1 subwoofer<\/strong><\/td><td class=\"column-2\">Smaller rooms, stereo setups, or one main listening position<\/td><td class=\"column-3\">Adds low-end weight without overcomplicating the setup<\/td>\n<\/tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\"><strong>2 subwoofers<\/strong><\/td><td class=\"column-2\">Medium to larger rooms, home cinema, or multiple seats<\/td><td class=\"column-3\">Gives smoother, more even bass across the room<\/td>\n<\/tr>\n<tr class=\"row-4\">\n\t<td class=\"column-1\"><strong>3-4 subwoofers<\/strong><\/td><td class=\"column-2\">Dedicated cinema rooms or awkward spaces<\/td><td class=\"column-3\">Helps reduce bass dead spots and gives more consistent coverage<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<!-- #tablepress-150 from cache -->\n<p>[\/et_pb_text][et_pb_button url_new_window=&#8221;on&#8221; button_text=&#8221;SHOP SUBWOOFERS&#8221; button_alignment=&#8221;center&#8221; _builder_version=&#8221;4.18.0&#8243; _module_preset=&#8221;default&#8221; custom_button=&#8221;on&#8221; button_text_size=&#8221;14px&#8221; button_text_color=&#8221;#FFFFFF&#8221; button_bg_color=&#8221;#0e95cf&#8221; button_border_width=&#8221;0px&#8221; button_border_color=&#8221;#0e95cf&#8221; button_font=&#8221;Arial|700|||||||&#8221; button_icon=&#8221;&#x35;||divi||400&#8243; button_icon_color=&#8221;#FFFFFF&#8221; custom_padding=&#8221;10px|30px|10px|30px|false|false&#8221; hover_enabled=&#8221;0&#8243; box_shadow_style=&#8221;preset6&#8243; box_shadow_blur=&#8221;2px&#8221; global_colors_info=&#8221;{}&#8221; theme_builder_area=&#8221;post_content&#8221; button_url=&#8221;https:\/\/www.av.com\/subwoofers&#8221; sticky_enabled=&#8221;0&#8243;][\/et_pb_button][et_pb_text _builder_version=&#8221;4.18.0&#8243; _module_preset=&#8221;default&#8221; custom_padding=&#8221;20px||||false|false&#8221; hover_enabled=&#8221;0&#8243; border_width_top=&#8221;2px&#8221; border_color_top=&#8221;gcid-45928375-1fd3-4d7e-b1f0-0adee316b54f&#8221; global_colors_info=&#8221;{%22gcid-45928375-1fd3-4d7e-b1f0-0adee316b54f%22:%91%22border_color_top%22%93}&#8221; theme_builder_area=&#8221;post_content&#8221; admin_label=&#8221;How many subwoofers do I need?&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_many_subwoofers_do_I_need\"><\/span>How many subwoofers do I need?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h4><span class=\"ez-toc-section\" id=\"Assessing_the_space_and_matching_your_subwoofer\"><\/span>Assessing the space and matching your subwoofer<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Before deciding how many subwoofers you need, be conscious of the space you\u2019re working with. You don\u2019t need to get weirdly intense with it, but measuring the room is useful. A 3x2m bedroom, a normal living room, and a larger open-plan space will all deal with bass differently.<\/p>\n<p>You should also think about where you&#8217;ll be sitting. If you\u2019ve got one main listening position, one well-placed sub might be enough. If you\u2019re covering a full sofa, multiple seats, or a proper home cinema setup, two subs can make more sense. In larger or open-plan rooms, bass can wander off a bit, so more than one subwoofer may be the better answer.<\/p>\n<p>You also want the sub to suit the rest of your system. A 12-inch sub isn\u2019t automatically better if it\u2019s wrong for your room, your speakers, or what you actually listen to. If you\u2019re using large floorstanders with decent-sized bass drivers, a tiny compact sub probably won\u2019t add much beyond a bit of extra rumble. Likewise, if you\u2019ve got small bookshelf speakers in a small room, a huge cinema sub might be more hassle than help.<\/p>\n<p>The aim is for the subwoofer to support your main speakers, not sound like it belongs to a completely different system. When it\u2019s matched well, you shouldn\u2019t really notice it as a separate thing. The whole setup should just feel like it has more depth, weight, and control.<\/p>\n<p>Also, don\u2019t ignore how it looks. Once a subwoofer gets big enough, you\u2019re probably not hiding it, so finishes, colours, and furniture-friendly designs start to matter. <a href=\"https:\/\/www.av.com\/rel-acoustics\" target=\"_blank\" rel=\"noopener\"><strong>REL<\/strong> <\/a>offer a lot of their subs in various finishes to match aesthetics, such as the T\/9X range in a variety of colours, including some vintage racing <a href=\"https:\/\/www.av.com\/Speakers\/REL-T-9x-SE-Subwoofer-Le-Mon-Yellow\/6QJM\" target=\"_blank\" rel=\"noopener\"><strong>colours <\/strong><\/a>to make more of a &#8216;thing&#8217; of them, as well as their <a href=\"https:\/\/www.av.com\/Speakers\/REL-Classic-99-Subwoofer-Walnut\/6KV6\" target=\"_blank\" rel=\"noopener\"><strong>Classic 99<\/strong><\/a>, and <a href=\"https:\/\/www.av.com\/Speakers\/REL-Planar-PL-2-Subwoofer-Gloss-Black\/84YZ\" target=\"_blank\" rel=\"noopener\"><strong>Planar<\/strong> <\/a>series.<\/p>\n<p>REL also offer a<strong>\u00a0<a href=\"https:\/\/rel.net\/pages\/room-set-up#sectionRoomSetup\" target=\"_blank\" rel=\"noopener\">Room Setup Tool<\/a><\/strong>\u00a0and a <a href=\"https:\/\/rel.net\/pages\/speaker-pairings\" target=\"_blank\" rel=\"noopener\"><strong>Speaker Pairing Tool<\/strong><\/a> on their site, which are excellent resources to look at, even if you aren&#8217;t in the market for a REL subwoofer.<\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"One_subwoofer\"><\/span>One subwoofer<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>For a lot of people, one subwoofer is absolutely enough. If you\u2019re working with a smaller room, a stereo setup, a desk system, or one main listening position, I\u2019d usually start with one good sub rather than immediately assuming you need two.<\/p>\n<p>The big benefit is simplicity. One sub is easier to place, easier to cable, and easier to dial in. You can spend a bit more time getting the crossover, level, and positioning right, rather than trying to balance multiple boxes at once. And when it\u2019s set up properly, it shouldn\u2019t sound like \u201ca subwoofer has been added\u201d. It should just make your speakers feel like they reach a bit lower and carry a bit more weight.<\/p>\n<p>This is especially true for music. A well-matched sub can add depth to bass guitars, kick drums, synth lines, and film scores without turning everything into a nightclub. The mistake is thinking one sub needs to do all the heavy lifting. It doesn\u2019t. It needs to support the main speakers.<\/p>\n<p>That\u2019s where scale matching comes in. If you\u2019ve got compact bookshelf speakers, a smaller sub might be ideal. If you\u2019re running bigger floorstanders, especially with larger bass drivers, you\u2019ll want something with enough size and control to keep up. Or, in some setups, two smaller well-placed subs might integrate more naturally than one oversized box trying to do everything by itself. But that leads us nicely onto\u2026<\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Two_subwoofers\"><\/span>Two subwoofers<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>This is where things get interesting, because two subwoofers doesn\u2019t just mean \u201cdouble the bass\u201d. I mean, yes, technically you\u2019ve got more bass available, but that\u2019s not really the point. The real reason to run two subs is to make the bass behave itself.<\/p>\n<p>With one subwoofer, you can end up with a great result in one seat and a slightly weird result somewhere else. Move along the sofa and suddenly the bass might feel heavier, thinner, or like it\u2019s gone missing entirely. That\u2019s not always the sub\u2019s fault. Rooms do strange things to low frequencies.<\/p>\n<p>Adding a second sub can help smooth that out. By placing two subs in different parts of the room, you can usually get more even low-end coverage across the space. That might mean one at the front and one towards the back, with the phase or delay adjusted so the bass reaches you in time.<\/p>\n<p>Get that wrong and you can end up with phase cancellation, where the sound waves start working against each other and all that hard work basically undoes itself. Annoying, but very real.<\/p>\n<p>Two subs can also work nicely with larger main speakers. Rather than asking one big sub to do all the heavy lifting, a well-matched pair can share the job and feel more natural in the room. They don\u2019t need to be huge either. In some spaces, two smaller subs will be easier to place and blend than one enormous box trying to dominate everything.<\/p>\n<p>So if one subwoofer is the simple option, two subwoofers are usually the more balanced option.<\/p>\n<hr \/>\n<h4><span class=\"ez-toc-section\" id=\"Three_or_four_subwoofers\"><\/span>Three or four subwoofers<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Three or four subwoofers is where you\u2019re getting into more serious home cinema territory. For most people, this isn\u2019t the starting point. It\u2019s what you look at when you\u2019ve got a larger room, multiple seating positions, or a space that just refuses to behave with one or two subs.<\/p>\n<p>The main benefit is consistency. Low frequencies are awkward, and rooms love making them even more awkward. You can have one seat where the bass feels huge, another where it feels thin, and another where everything gets a bit woolly. Adding more subs, placed carefully, can help smooth those differences out so the bass feels more even across the room.<\/p>\n<p>This is especially useful in a dedicated cinema room, where you\u2019re trying to give everyone a similar experience rather than making one seat sound brilliant and the rest feel like afterthoughts.<\/p>\n<p>That said, three or four subs only really make sense if you\u2019re willing to set them up properly. Placement, phase, delay, crossover, and level all matter. If you just throw four subwoofers into a room and hope for the best, you\u2019re not building a bass system. You\u2019re creating a low-frequency argument.<\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.18.0&#8243; _module_preset=&#8221;default&#8221; custom_padding=&#8221;20px||||false|false&#8221; hover_enabled=&#8221;0&#8243; border_width_top=&#8221;2px&#8221; border_color_top=&#8221;gcid-45928375-1fd3-4d7e-b1f0-0adee316b54f&#8221; global_colors_info=&#8221;{%22gcid-45928375-1fd3-4d7e-b1f0-0adee316b54f%22:%91%22border_color_top%22%93}&#8221; theme_builder_area=&#8221;post_content&#8221; admin_label=&#8221;FAQs&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<h3><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>FAQs<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h4><span class=\"ez-toc-section\" id=\"What_do_subwoofers_do\"><\/span>What do subwoofers do?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Subwoofers reproduce low-frequency sounds that standard speakers often struggle to deliver with depth and power.

If you\u2019re working with a smaller room, a stereo setup, or one main listening position, that will usually get you the low-end support you\u2019re after without making the setup more complicated than it needs to be.<\/p>\n<p>Two subwoofers are great if you want smoother bass across a wider seating area, especially in a home cinema or larger living room.

And yes, in principle, that\u2019s true. You can just slap a sub into a system, and it\u2019ll probably make things sound bigger. But if you actually want to integrate a subwoofer properly, there are a few things worth thinking about first.<\/p><p>The obvious question is: <strong>how many subwoofers do I need?<\/strong> Annoyingly, the answer isn\u2019t just \u201cone\u201d, \u201ctwo\u201d, or \u201cas many as you can sneak into the room before someone notices\u201d. It depends on your space, your main speakers, and what you\u2019re using the system for. A compact stereo setup in a small room has very different needs to a dedicated home cinema with multiple seats.<\/p><p>It\u2019s also about scale. The sub needs to make sense with the rest of the system and the room it\u2019s going in. A tiny sub won\u2019t do much for big floorstanders, and a huge sub in a tiny flat could become more of a problem than an upgrade.<\/p><p>Subwoofers now come in all sorts of sizes, shapes, and finishes too, so placement and aesthetics are super important.<\/p><p>So, let's get into how many subwoofers you actually need!<\/p><hr \/><h3>Key takeaways<\/h3><p>[table id=150 \/]<\/p><hr \/><h3>How many subwoofers do I need?<\/h3><h4>Assessing the space and matching your subwoofer<\/h4><p>Before deciding how many subwoofers you need, be conscious of the space you\u2019re working with. You don\u2019t need to get weirdly intense with it, but measuring the room is useful. A 3x2m bedroom, a normal living room, and a larger open-plan space will all deal with bass differently.<\/p><p>You should also think about where you'll be sitting. If you\u2019ve got one main listening position, one well-placed sub might be enough. If you\u2019re covering a full sofa, multiple seats, or a proper home cinema setup, two subs can make more sense. In larger or open-plan rooms, bass can wander off a bit, so more than one subwoofer may be the better answer.<\/p><p>You also want the sub to suit the rest of your system. A 12-inch sub isn\u2019t automatically better if it\u2019s wrong for your room, your speakers, or what you actually listen to. If you\u2019re using large floorstanders with decent-sized bass drivers, a tiny compact sub probably won\u2019t add much beyond a bit of extra rumble. Likewise, if you\u2019ve got small bookshelf speakers in a small room, a huge cinema sub might be more hassle than help.<\/p><p>The aim is for the subwoofer to support your main speakers, not sound like it belongs to a completely different system. When it\u2019s matched well, you shouldn\u2019t really notice it as a separate thing. The whole setup should just feel like it has more depth, weight, and control.<\/p><p>Also, don\u2019t ignore how it looks. Once a subwoofer gets big enough, you\u2019re probably not hiding it, so finishes, colours, and furniture-friendly designs start to matter. <a href=\"https:\/\/www.av.com\/rel-acoustics\" target=\"_blank\" rel=\"noopener\"><strong>REL<\/strong> <\/a>offer a lot of their subs in various finishes to match aesthetics, such as the T\/9X range in a variety of colours, including some vintage racing <a href=\"https:\/\/www.av.com\/Speakers\/REL-T-9x-SE-Subwoofer-Le-Mon-Yellow\/6QJM\" target=\"_blank\" rel=\"noopener\"><strong>colours <\/strong><\/a>to make more of a 'thing' of them, as well as their <a href=\"https:\/\/www.av.com\/Speakers\/REL-Classic-99-Subwoofer-Walnut\/6KV6\" target=\"_blank\" rel=\"noopener\"><strong>Classic 99<\/strong><\/a>, and <a href=\"https:\/\/www.av.com\/Speakers\/REL-Planar-PL-2-Subwoofer-Gloss-Black\/84YZ\" target=\"_blank\" rel=\"noopener\"><strong>Planar<\/strong> <\/a>series.<\/p><p>REL also offer a<strong>\u00a0<a href=\"https:\/\/rel.net\/pages\/room-set-up#sectionRoomSetup\" target=\"_blank\" rel=\"noopener\">Room Setup Tool<\/a><\/strong>\u00a0and a <a href=\"https:\/\/rel.net\/pages\/speaker-pairings\" target=\"_blank\" rel=\"noopener\"><strong>Speaker Pairing Tool<\/strong><\/a> on their site, which are excellent resources to look at, even if you aren't in the market for a REL subwoofer.<\/p><hr \/><h4>One subwoofer<\/h4><p>For a lot of people, one subwoofer is absolutely enough. If you\u2019re working with a smaller room, a stereo setup, a desk system, or one main listening position, I\u2019d usually start with one good sub rather than immediately assuming you need two.<\/p><p>The big benefit is simplicity. One sub is easier to place, easier to cable, and easier to dial in. You can spend a bit more time getting the crossover, level, and positioning right, rather than trying to balance multiple boxes at once. And when it\u2019s set up properly, it shouldn\u2019t sound like \u201ca subwoofer has been added\u201d. It should just make your speakers feel like they reach a bit lower and carry a bit more weight.<\/p><p>This is especially true for music. A well-matched sub can add depth to bass guitars, kick drums, synth lines, and film scores without turning everything into a nightclub. The mistake is thinking one sub needs to do all the heavy lifting. It doesn\u2019t. It needs to support the main speakers.<\/p><p>That\u2019s where scale matching comes in. If you\u2019ve got compact bookshelf speakers, a smaller sub might be ideal. If you\u2019re running bigger floorstanders, especially with larger bass drivers, you\u2019ll want something with enough size and control to keep up. Or, in some setups, two smaller well-placed subs might integrate more naturally than one oversized box trying to do everything by itself. But that leads us nicely onto\u2026<\/p><hr \/><h4>Two subwoofers<\/h4><p>This is where things get interesting, because two subwoofers doesn\u2019t just mean \u201cdouble the bass\u201d. I mean, yes, technically you\u2019ve got more bass available, but that\u2019s not really the point. The real reason to run two subs is to make the bass behave itself.<\/p><p>With one subwoofer, you can end up with a great result in one seat and a slightly weird result somewhere else. Move along the sofa and suddenly the bass might feel heavier, thinner, or like it\u2019s gone missing entirely. That\u2019s not always the sub\u2019s fault. Rooms do strange things to low frequencies.<\/p><p>Adding a second sub can help smooth that out. By placing two subs in different parts of the room, you can usually get more even low-end coverage across the space. That might mean one at the front and one towards the back, with the phase or delay adjusted so the bass reaches you in time.<\/p><p>Get that wrong and you can end up with phase cancellation, where the sound waves start working against each other and all that hard work basically undoes itself. Annoying, but very real.<\/p><p>Two subs can also work nicely with larger main speakers. Rather than asking one big sub to do all the heavy lifting, a well-matched pair can share the job and feel more natural in the room. They don\u2019t need to be huge either. In some spaces, two smaller subs will be easier to place and blend than one enormous box trying to dominate everything.<\/p><p>So if one subwoofer is the simple option, two subwoofers are usually the more balanced option.<\/p><hr \/><h4>Three or four subwoofers<\/h4><p>Three or four subwoofers is where you\u2019re getting into more serious home cinema territory. For most people, this isn\u2019t the starting point. It\u2019s what you look at when you\u2019ve got a larger room, multiple seating positions, or a space that just refuses to behave with one or two subs.<\/p><p>The main benefit is consistency. Low frequencies are awkward, and rooms love making them even more awkward. You can have one seat where the bass feels huge, another where it feels thin, and another where everything gets a bit woolly. Adding more subs, placed carefully, can help smooth those differences out so the bass feels more even across the room.<\/p><p>This is especially useful in a dedicated cinema room, where you\u2019re trying to give everyone a similar experience rather than making one seat sound brilliant and the rest feel like afterthoughts.<\/p><p>That said, three or four subs only really make sense if you\u2019re willing to set them up properly. Placement, phase, delay, crossover, and level all matter. If you just throw four subwoofers into a room and hope for the best, you\u2019re not building a bass system. You\u2019re creating a low-frequency argument.<\/p><hr \/><h3>FAQs<\/h3><h4>What do subwoofers do?<\/h4><p>Subwoofers reproduce low-frequency sounds that standard speakers often struggle to deliver with depth and power. They make bass, drums, explosions, and other low sounds feel fuller, adding greater impact and realism to music, films, and games.<\/p><hr \/><h4>Do subwoofers just play bass?<\/h4><p>Subwoofers primarily play bass and other low-frequency sounds rather than the full audio spectrum. They handle frequencies that regular speakers may reproduce less effectively, providing deeper bass while allowing the main speakers to focus on midrange and treble.<\/p><hr \/><h4>Do you actually need a subwoofer?<\/h4><p>A subwoofer is not always necessary, but it can significantly improve sound quality when deep, powerful bass matters. Smaller speakers often benefit most from one, while large full-range speakers may already provide enough bass for everyday music and listening.<\/p><hr \/><h3>Final thoughts<\/h3><p>So,<strong> how many subwoofers do you need?<\/strong> For most people, the answer is probably one good, well-matched subwoofer. If you\u2019re working with a smaller room, a stereo setup, or one main listening position, that will usually get you the low-end support you\u2019re after without making the setup more complicated than it needs to be.<\/p><p>Two subwoofers are great if you want smoother bass across a wider seating area, especially in a home cinema or larger living room. Three or four is more specialist territory, and really only worth looking at if you\u2019ve got the space, the system, and the patience to set them up properly.<\/p><p>The main thing is to think about scale. Match the sub to your speakers, match it to your room, and be realistic about what you actually need. More bass is fun, obviously, but better bass is what you\u2019ll actually want to live with.<\/p>","_et_gb_content_width":"","_monsterinsights_skip_tracking":false,"footnotes":""},"categories":[60,63,139,6,5],"tags":[108,19,44,40],"class_list":["post-49077","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-hifi-guides","category-home-cinema-guides","category-guides-2","category-hifi","category-home-cinema","tag-blog-category-guides-2","tag-hi-fi","tag-home-cinema","tag-subwoofers"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>How Many Subwoofers Do I Need?
