How to build a surround sound system - our guide to super-charged sound in your living room

An amazing surround sound system is something many of us would love to have in our homes, but it is also something that can be hard to make a start on. With the popularity of soundbars and Bluetooth speakers booming over the last few decades, true home theater systems made up of multiple speakers can seem overwhelming.

But building the best surround sound system is relatively simple and can be done in a variety of ways depending on your comfort level and experience. For example, you can go for a complete kit with everything you need, or you can pick and choose which speakers you want or need for a tailor-made system.

In this article, we will go through the different elements of surround sound, which speakers are good for which elements of your audio, and whether true surround sound is actually worth it over more streamlined options.

1. DIY or ready-made system?

The first thing you need to do is decide whether a ready-made surround sound system or a more DIY approach is right for you. The former means you will get a set of speakers ready to be connected, while the latter takes a little more thought but is easier to expand gradually.

Setting up a DIY system requires assembling only the speakers you need or have the space for, with the option to add more in the future. Many brands offer both, with starter kits and standalone speakers, subwoofers, and soundbars that can be added to the system whenever you choose.

A 5.1 surround sound system will be made up of two front-facing speakers, two rear speakers, a center speaker, and a subwoofer.

2. Choose your AV receiver and initial speakers

True surround sound systems require an AV receiver to work together, so this should be your first step. Many ready-made surround sound systems will include these, but some will not, and if you are purchasing separate speakers to create your own system, you will need to add an AVR.

After this, the center channel needs to be your next concern. According to Klipsch (opens in new tab),  this center speaker is responsible for around 60% of the dialogue output, so a good one is essential for those using their surround sound system with a TV. 

If you have a particular brand in mind, like Sonos, Sony, or Bang & Olufsen, you will want to ensure that your receiver, speakers, subwoofer, and (if included) soundbar are compatible with one another. The best way to do this is to stick to one brand for everything, but some will allow you to mix and match.

A good first step after the AVR is the center and surround speakers. Soundbars like the JBL Bar 800 with additional speakers are a great way to achieve this easily and affordably, and it's a solid choice if your main purpose is making your TV sound better. Often, choosing a soundbar system also eliminates the need for a receiver.

3. Add a compatible subwoofer and additional speakers

The next step is floor-standing speakers and the best subwoofer, which will take your sound system to the next level. As already explained, high-end soundbars will often come with their own rear speakers and subwoofer, but floor-standing speakers are an extra you will need to purchase seperately.

Unlike bookshelf speakers, floor-standing speakers should be 'floating' away from walls and at an equal distance from the center speaker on either side. It's common to place them on each side of a TV or HiFi unit, facing the sofa or other seating. The subwoofer, meanwhile, is responsible for much of the depth and bass of your audio.
