The Tropo series is our most versatile subwoofer and is affectionately called Kickass. And the Tropo 6.5 Inch D4 is the smallest one of them. It has 200 watts RMS and 400 watts MAX power. It features a 4-layer copper Dual 4 Ohm voice coil and packs with a double-stacked Y30 ferrite magnet that offers tremendous motor force in a little space. The cone is made of polypropylene composite paper, reinforced with 3% carbon fiber. With a more potent motor, bigger voice coils, and optimized suspension, the Tropo series has become the SQ oriented driver within CT Sounds lineup and does so without sacrificing sub-bass output. It is an excellent choice for all applications without breaking the bank. Your friends will be impressed and will be blown away with the performance at its price point.
