Tropo 18s

I was extremely surprised at their performance. Bought 4 of them and put them in a ported flatwall on a single Wolfram 4500.1 wired at .5 ohm. It’s a great demo setup and perfect match!

Hiting the lows on bass and wallet

Great budget subs. Get down low and do very well for the price. You'll be pleasantly suprised by these suckers. Will be doing 3 of these behind the 3rd row of a suburban. (Currently have 2) so keep an eye out on youtube for me.

Built like a tank

Solid Build. Haven't pushed it to its RMS yet but sounds great.

Tropo xl 12 inch

These subwoofers are by far the best product I've bought. The price for the performance is staggering and i need to line more panels in my car with hush mat because of the rattling. Definitely a recommended product and planning to purchasing some 6x9 meso series.

This thing pounds!!

I love it and I am waiting for an amp to be available to go with the sub!!! Kicker has some competition!!

Nice

Super fast and nice

The Best Subs for the money period

Bought two tropo xl 10 d4’s wired them to 1 ohm on a 1000 watt amp. These subs have exceeded every expectation I had for them in every aspect Coleman Thedinger is doing great things for the CT Sounds Community. Looking forward to many more of these great products.
