Boston Acoustics GTR12 TunableRadiator
12" passive radiator for use with Boston G5 subwoofers (Black)
Would you like to add extra bass to your system without taking up extra space or adding more power? Boston's GTR TunableRadiators are "passive radiators" — shallow, non-powered speakers designed to be used in conjunction with Boston G5 subwoofers. When mounted into a box along with a G5 sub, the radiator's cone moves with the air pressure created by the powered G5 sub, reinforcing bass output without requiring extra power.
Adding this GTR12 passive radiator to a sub box with a 12" G5 subwoofer can increase output by up to 3 dB — that's almost twice the volume. And, since it's only 3 inches deep, you can add it to almost any sub box. The GTR12 has three tuning modes, allowing the listener to adjust the sound and bass output to their musical preferences and box size.
