The fundamental principle behind Echo Busters is simple. Before
you spend another dollar on audio equipment, upgrade the one component
that will give you back your greatest rewards, your room! Only with
an acoustically balanced room can you attain state-of-the-art sound
reproduction. Echo Busters improve the acoustics in your room, creating
a truly realistic soundstage. Echo Busters treat rooms effectively,
inexpensively and, best of all, decoratively.
