Great buy!!

The following review is for 10TK, which is a part of the bundle you are viewing.

This box is built right and is high quality. I have a kicker 10 compRT in the box and it thumps hard. For anyone looking for a good single 10 enclosed box then I would highly recommend buying this one.

JL replacement that bangs

The following review is for UFO10, which is a part of the bundle you are viewing.

So this shallow mount sub was purchased to replace a blown JL Audio 10WX-4. I was like a kid on Christmas Eve waiting for its arrival. I promptly unboxed and pulled the old JL and was going to mount the new sub, but had to widen the cutout (as expected). Once I got the cutout widened, I mounted this beast (I dialed in the JL J2 250 amp settings prior to widening the cutout). I wired everything up (sub at 2 ohm), made some micro adjustments to the amp and external crossover settings and was ready to rock and roll. This sub did not disappoint in any way, shape or form and sounds amazing!!! (I think it sounds better than the JL) This was a great choice and I’m glad I bought it. For a little old 10” sub, it played artists like Firehouse, Beastie Boys, Bass Mekanik, contemporary Christian, blues, 90s rap and some more genres flawlessly. It has some pretty good bump for being in a small sealed box. I actually think the JL amp is a little underpowered, but it still sounds amazing and so far, I am highly satisfied with this sub. If you’re thinking about buying it and are on the fence, DO IT!!!! You won’t be disappointed.
