About: CT Sounds TROPO-8 D2  400 Watts RMS 8" Car Subwoofer

The Tropo 8 Inch D2 is our most versatile subwoofer and is affectionately called Kickass. It has 400 watts RMS and 800 watts MAX power that offers a significant performance advantage over the same size Bio Subwoofer. 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 features a 4-layer copper Dual 2 Ohm voice coil. The cone is made of polypropylene composite paper, reinforced with 3% carbon fiber. The motor is a double-stacked Y30 ferrite magnet that offers tremendous motor force and weighs 91% more than the same size Bio Subwoofer. 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.
