Massive Audio 8" 800 Watt Subwoofer Dual 4 Ohm Shallow Mount SUMMO84S
Maximize Bass Reproduction and save on airspace via this innovative new design! This new cast basket and sealed bottom plate design will replace traditional bottom venting by redirecting the cooling from the pole piece vent to the bottom of the customized basket. this allows the subwoofer to be installed where the depth is limited. By bolting this machine screw through the back of the enclosure to the backplate of the subwoofer you will minimize 'box flexing' and reduce the airspace needed in the box itself! Minimizing box flexing will increase efficiency by converting the wasted electrical power from the amplifier directly to the mechanical linear subwoofer cone's movement which will minimize distortion and add more efficient bass reproduction.
