Tropo 6.5’s

After looking at these for two years I finally pulled them out of the boxes and built a 4th order for them.... All I can say is wow!!!! On a skar 1500.1 @1 ohm and they sound amazing! You can tell it’s not a big sub sound but plays very musically!! Might get two more and build the same box again and tie them together

Nice little subwoofer

Bangs for it being so small been playing with a D4 looking at getting another 1 or 3 lol

Great bass cannon

This little bass cannon paired with the apropriet subwoofer will stand up and talk to you.
