How many surround speakers does your living room actually need?

A great home theater system isn’t a necessity, but who’s going to argue with the kind of immersive audio that will put your local movie theater to shame? If you’re considering investing in an AV receiver and several speakers for your living room, you’ll first need to determine how many speakers you’ll need to create your surround sound setup. The short answer is that it ultimately depends on the size of your room and your budget.

At the most basic level, a proper surround sound setup consists of three front speakers (the left, right, and center channels), two rear, and a subwoofer. This classic configuration is presented as a 5.1 configuration, which formats like Dolby Digital and DTS can benefit from. If you’re working with a small footprint, a 5.1 system may be enough. If your living room is Really tiny, you could potentially get away with a 3.1 (no rear), 2.1 (no rear or center), or 2.0 (no rear, center or under) configuration. Technically, however, these three speaker arrangements are not “true” surround sound setups.

In a 3.1, 2.1, or 2.0 configuration, you only hear directly streamed audio has you, not around You. That said, the great thing about building a home theater is that you can do it in stages. If you don’t have the funds for a full 5.1 or higher system, start with a 2.1 or 2.0, then add rear speakers when you can afford them.

Floor-standing speakers make for an attractive home theater visual, and some living rooms will benefit from the expansive sound they deliver. Other theater spaces may barely have enough room to accommodate bookshelf speakers, which is another reason to know the square footage you’re working with. Although you can install height speakers in your living room, placing floor speakers in an acoustically problematic area (for example, the walls are too close to the speakers) can result in muddy, bass-boosted sound that will quickly be overwhelmed. You’ll also find that many good speakers have ports on the back that improve bass quality by expelling air. These speakers should be placed at least two feet from the wall for best results.

Knowing your limits is essential to building a home theater, but just because you can’t install large speakers doesn’t mean you’re compromising the overall power and immersion of your system. There are many excellent bookshelf speakers on the market, and many can be combined with stands and wall mounts if there is no bookshelf or entertainment center to use. We haven’t yet touched on the fact that a great home theater soundbar can deliver a “virtualized” surround sound experience even without speakers physically surrounding you, thanks to design elements like side-mounted and up-firing speakers.

Wait a minute, you might be wondering: what are side and up-firing speakers? There’s another layer to this whole surround sound thing. Some speakers send sound in multiple directions instead of just transmitting it directly, which contributes to the feeling of being surrounded by sound. If you have enough space, you can opt for a 7.1 configuration, which adds two side speakers towards the center of your system.

Then there are Dolby Atmos/DTS:X configurations that use a “XXX” label, which corresponds to speakers, subwoofers, and height channels. This type of surround sound introduces vertical audio effects, which can be delivered through ceiling speakers or floor-level speakers with top-mounted speakers. The latter emits sound upward towards your ceiling and back down, which is not quite the same as a ceiling speaker radiating sound downward.

One of the main drawbacks of a true Atmos setup is the additional amount of equipment and potential labor required to install everything. This is why many apartment dwellers opt for a high-end soundbar rather than a multi-channel speaker system. But if you have the space, money, and initiative to make full use of Atmos, we highly recommend doing so.

As you can see, there is no simple answer to the question of how many surround speakers your living room should accommodate. Ultimately, a “great” 5.1 system can outperform a “good” or “good” 7.1 or Atmos setup. As long as you’re not disturbing your neighbors or emptying your bank account, the right number of surround speakers is the number that best suits your finances and lifestyle at any given time.
