Congrats on getting your 5.1 home theater system and you are wise to know that speaker placement is crucial in having high surround sound quality. If the couch you are sitting on when watching movies is right up against the wall, no worries, there is a 5.1 speaker placement for such a case.
Best 5.1 Speaker Placement when your Couch is Against the Wall
Let’s start with the center channel speaker placement first, it should be placed below and at the center of the screen, facing directly to the sweet spot or the couch without any angles. The center speaker should be at your ear level when you are sitting down on the couch.
The left and right front channel speakers should be placed beside the center channel speaker. How far apart these left and right speakers need to be will depend on the manufacturer’s recommendation or around 6 feet (1.5m-2.0m). The tweeters of these L/R main channel speakers should be at your ear level as well or slightly above. Some speakers will require you to angle them towards the sweet spot, there are a few models which do not need to due to the way the sounds are been dispersed. Your L/R main channel speakers can be placed further toward you, and this will depend on how much distance they need to be away from the rear walls.
The subwoofer is usually at the front too, placed in the corner of your room. We do recommend using the subwoofer crawl method to determine the most optimal placement where it will provide you with the best bass performance.
The two surround speakers are supposed to be placed slightly behind the couch and angled towards the sweet spot but because your couch is against the wall, this placement wouldn’t be applicable. For this situation, you can place the two surround speakers one on each side of the couch and they will be facing directly towards the sweet spot. There’s no need to place them too close to the couch, some distance away would be fine. The tweeters of the surround speakers should be at your ear level or slightly higher. Make sure the sofa arms are not partially blocking the surround speakers’ as this will affect the sound quality.
You should use auto room correction technology such as Audyssey when you have completed placing the speakers. It should optimize the surround sound to be more seamless and immersive. If your speakers are new, you should use the room correction technology again once all of them have break-in.
Just a little added information for you, the surround speakers placement mentioned earlier will not work for 7.1 and above home theater setup. As you will need to position the two rear surround speakers behind the couch or sitting position.
Just follow this setup guide and you will be rocking your 5.1 home theater system in no time even if your couch is against the wall. It will be better to place the surround speakers slightly behind you though, maybe is possible to push the sofa out a bit? Still, you probably have your reasons why you position the couch against the wall. And if one of the reasons is that you have very limited space, you might want to go for a 2.1 setup instead. You can read more about 2.1 or 5.1 surround sound on our website. Worried that the movie dialogues are not clear enough if you are using a 2.1 sound system then how about setting up a 3.1 HT system. We’ve written an article about 2.1 vs 3.1 and you can check it out to learn more.
You can play around with the surround speakers’ angles and distance. Do some experiments to see which angle and distance away from the sofa give you the best surround sound quality. There are listeners who find that they get more immersive sound when the surround speakers are pointed away from the sweet spot. Just have fun with the experimenting process, you can always set them back to the standard 5.1 speaker placement using this guide here.
