300mm BASS REFLEX SUBWOOFER BOX
High-efficiency polypropylene woofer cones - This lightweight and popular cone material is used to ensure maximum woofer efficiency. The benefit is high output with modest amplifier power.
Large-roll rubber surrounds - This material provides optimum cone-edge suspension and absorbs distortions that may travel up the cone edge. The benefit is reduced distortion.
Progressive spider - Each GT4 subwoofer features a progressive spider, which provides better control at excursion limits than a linear spider. The benefit is reduced distortion at high output levels.
Deep-draw I-beam basket - This provides room for a longer motor structure, which provides increased bass output. This basket is also more rigid and has a lower basket resonance. The benefit is lower woofer distortion.
Vented polepieces - Additional cooling is provided to the motor structure. The benefit is that each GT4 subwoofer's thermal capabilities are augmented, increasing power handling.
12mm Linear one-way X-max and dual 1100 grams (2200 grams) magnets make this subwoofer a great choice for high output applications.
Custom-tuned bass reflex systems acoustically optimized for the in-car environment.
Precision-tuned for extended, powerful deep bass
