Audison Prima APS 10D shallow mount subwoofer. 10" shallow mount sub, basically brand new. I bought this new from stereo shop, but my amp wasn't strong enough to get the bass I wanted from it, so went back to my old bulky setup. Basically brand new, maybe about 20 hours of use if that. Tried using a focal P25f after that same issue, box I was using wad just too small. Retails for $369... selling to less than half price. Asking $150. If your looking at Audison then you know what your looking at. Pickup in upland Trolls, low ballers, blah blah blah will be ignored. Thanks for looking. And can test if needed, but like I said this is basically brand new with very little use.
