The Strato 8 Inch D4 is CT Sounds all-around ground-pounding subwoofer. This 450 watts RMS and 900 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.

Strato 8 Inch D4 Subwoofer
For a small sub it has a lot of punch 4th order box
Received them, just haven't had the opportunity to install them as of yet. The look fantastic, and appear to be really well built.
The level of quality and extraordinary sound of this little yet heavy Sub is one of the best I've ever heard from my any of my cars. Would readily recommend CT Sounds.
