The SC-BTT270 is the 5.1-channel version of the 2.1-channel SC-BTT262, but despite the increased number of speakers it still won't take up much extra space in your living room. That's because the supplied satellites are extremely compact, with each one measuring 80(w) x 117(h) x 70.5(d)mm. That makes them easy to accommodate on bookshelves and other furniture in the room, a far cry from the tall space-hogging towers supplied with the upmarket SC-BTT775 system.
