the w7 is fine theres nothing wrong with it, its a great all around woofer most people dont like it cuz its overpriced thats all but give the w7 the right amount of power and put it in the right box and it'll get pretty loud and at the same time it'll be accurate ive heard wut 1 10'' w7 can do its pretty loud rattled the insides of my ear abit but that was in a hatch either way i was pretty amazed
