With in-wall speakers, you can have a complete surround sound experience with full integration into any area of your home. In-wall speakers are great for home theatre setups, indoor audio systems, or outdoor sound equipment. They are highly customisable to accommodate a variety of amplifiers by using adjustable impedance, tweeter angle and volume. Size categories include up to 6 inches, 6.5 inches, 8 inches, and 10 inches, to accommodate any size requirements. As in-wall speakers do not provide high-depth bass levels, adding a subwoofer to these sound systems is highly recommended. Choose from a variety of cone types, including glass fibre, paper, poly cone, and synthetic fibre. Some mono-summing designs feature two tweeters and two speaker terminals, as well as weather resistant cones optimised for bathroom or outdoor environments. Brands include Krix, Selby, Polk, OpusOne, SONOS, and OEM.
