I would just like to say that the handwritten letter thanking me for showing interest in the company honestly made me tear up, that personal touch really hit me in my feeling hard and I love this company even more for it! I bought an "open box" tropo 12 d4 (that was never opened by the original purchase of the product. When it showed up (faster than a jackalope) to my front door I rushed home to open it. Upon opening this product I gazed at it's pristine condition and immediately went outside with (my middle child in tow) to install it into the existing box/amp from a previous setup that was still in my trunk, I turned on my head unit at completion and it was at that moment i realised that there will never ever be another sub in my car that isn't a c.t. product!!!! I was amazed at the clarity and the depth of the bass and the overall quality that the product appears to have as well is superb, the fact that I got this sub for a substantial discount was just icing on the rich moist cake. Thank you C.T. SOUNDS! And thank you Bart for keeping Colemans vision with all of us that really love and enjoy these products!!!

Tropo XL 12 D4 subwoofer review

I'm very impressed with the product quality, ruggedness, and sound quality from the sub. I have used many other vendor products in the past, JBL, Infinity, Fosgate. CT sounds is definitely a step above these vendors. I have recently purchased an AT-1400.1D amp, can't wait to get it. I'm very happy i switched to CT sounds!!

Love them


Holy sh*t. Blown away, literally. I did a mix of a SPL & SQ build, and have 2 of these Champs wired to 1 ohm on a Ct1500.1 in a 4th order birch box ported through my back seat armrest. Not only do they take every bit of power I feed them, albeit I'm running them a little less than rated, but they can handle way more than that. Nice hard hitting bass, without that "ppfffttt" sound when the really low low's hit. As hard as they hit, they don't overshadow the vocals I have going either, they're perfect. Not to mention I can shake the windows over 4 cars up from me at red lights with them. Would definitely buy another set of them to put in another car again.


These are some great subs!!! Glad I bought them.
