The KEF E305 has everything you need for sweeping theater sound. This 5.1 set has 4 surround speakers, a center speaker and a powerful subwoofer. The 2-way design of the speakers produces bass and treble separately. This gives you a clear, rich sound, so you can hear every detail of your favorite movie soundtrack. The subwoofer is aimed downward and distributes the bass through the room evenly. This means the bass doesn't just sound heavy, it also subtly matches the sound of the spakers.
