Could not be happier! Kills any 15 I’ve ever heard! Punchy, deep, clean lows you can feel! I’m using an external crossover and only asking this sub to do everything below 60 hz and believe me it thumps. Not quite as deep as my dxs 18’s but what do you expect from a 12. And half the wreight!!! My favorite piece of equipment easy! Love zZounds also! Been good to me!
