The Strato 12 Inch D2 is CT Sounds all-around ground-pounding subwoofer. This 1200 watts RMS and 2400 watts MAX power feature-packed subwoofer delivers stellar sub-bass extension without distortion. It is even more powerful and has a bigger voice coil than the same size Tropo subwoofer. It has a double-stack Y35 ferrite magnet compared to the Y30 ferrite magnet of Tropo. The voice coil is improved as well, with 4-layers of CCA instead of copper, allowing faster heat dissipation and cooling. The cone on the Strato is also stiffer than the Tropo to allow for increased rigidity, and lower distortion at extremely high SPL levels. The Strato improved cone is a nylon composite paper reinforced with 4% carbon fiber. The Strato comes with a cast aluminum basket which is more durable than stamp steel basket. It is a client favorite, not only because of its out-of-this-world performance for the dollar paid but also for its wow factor. Your friends will be drooling with envy. It is called bad-to-the-bone for a reason.
