Don’t expect sound quality from this thing but its output is impressive when ported in the correct box. Fun sub to play around with and the trim ring makes it look decent when installed. After trying a few the reliability can be spotty even with conservatively set gains (don’t go over ~150W-180W RMS). Cone was not centered correctly on the last one I ordered making logo looked cocked when installed and basket is made out of the thinnest metal I’ve seen used on a sub. Still outpounds other subs costing twice the price while using less power.
