The Tropo 15 Inch D2 is our most versatile subwoofer and is affectionately called Kickass. It has 650 watts RMS and 1300 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 the 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.

Smooth and clean bass
They hit lows pretty dang good. A very sq oriented sub. When I got it tho it did not fit in my box perfect, the basket was too big, otherwise this is a pretty good budget sub, don’t recommend if you want hardcore bass. You can see In the picture how it is slightly bigger than a normal 15” (The rattle in the video is my box not the sub)
Installed 2 Tropo 15’s on a 1400.1d amp and they are pounding. Great all around subwoofer that sounds good with all types of music. I could not be happier with this product. If you are not buying CT Sounds equipment, you are missing out. Quality product, great pricing, and excellent customer service.
This is my fifth 15 inch tropo that I bought I have one in my van two in my sons car and now two in my girlfriends car and let me Tell you. I will continue to buy them. The next thing I’m gonna try is there amplifiers And they always buy their blueprints for the sub boxes I have tried different sub boxes but these are built specifically for these subwoofers and let me Tell you they slam
Recently I purchased a pair of Tropo 15's for my Jeep Compass and couldn't be happier. The sound quality is amazing Thank You CT Sounds. Joe Pharris
