Our expert team reviews products in dedicated test rooms, to help you make the best choice for your budget. Find out more about how we test. The first thing to consider is the number of channels. A 5.1 system is most common and comprises five speakers (two pairs of either floorstanding or standmount speakers and one centre speaker) and one subwoofer. Other arrangements are also available, from 7.2, which adds surround back speakers behind your seating position and an extra subwoofer, up to pretty much whatever your room can hold. Dolby Atmos systems tend to include up-firing speakers that can help deliver more immersive surround sound, but make sure your speakers are compatible and they're paired with a capable AV receiver. Alternatively, you can achieve Atmos with in-ceiling speakers. More speakers usually mean more convincing surround sound, although they can take up quite a bit of space. You'll also need to factor in the cost (and positioning) of speaker cable. Keeping your selection of speakers to one brand will help keep the sonic balance. This is especially the case with the centre speaker, which should be from the same brand and ideally from the same range as the rest of your home theatre speaker system. This will help ensure the best sound possible. Finally, price is key. You can spend a few hundred or tens of thousands, so make sure you peruse this list and find one that fits your budget. If you own a budget AV receiver there's no point partnering it with a high-end speaker package. As a general rule of thumb, we'd suggest spending around double the cost of your surround sound amp on a standard 5.1 speaker set-up. All the speaker packages recommended below have been through our thorough testing process and they've passed with flying colors. So whether you're after a budget set-up or the kind of home cinema system that would make Bruce Wayne green with envy, we should have something for you.
