i bought this sub alone no box, for my van to get some extra boom without takin a lot of space. built my own box to sealed specs. i was completely blown away at the sound quality from this flat sub. ive heard a lot of bad things about flat subs. pioneer figured out how to keep the boom without the space. great sub, great price. buy at least 2 of em.

I've had this for about a month now and it is wonderful!. I've got it under the rear seat of a 2008 Toyota Tundra double cab and it really adds depth and low end to the music. I'm really surprized too, because the enclosure itself is pretty small. I've got it set so the woofer faces down (as designed) and it adds plenty of bass. My truck also has dynamat in it (from the previous owner), so that may be helping with the bassiness. The enclosure is sealed and solidly built. There isn't any carpet on the top or bottom though...only on the sides. The spring connections on the side are solid and secure. I've got this thing paired with a Renegade 850S amp and it really sings. I set the crossover on the head unit to 80Hz for the sub and 80Hz for the bass. I'm running an older Clarion head unit (NX500) which allows me to control the sub boost too. I've got it set at +1 and that is plenty for me. This sub can thump, but I don't use it for that..I used it to add depth and for me it's perfect. If I had room, I'd add another.
