I dont know, like posted above.... I was expecting a bit more. Maybe b/c I hyped up this woofer in my tiny brain. The ads, and price tag all had me thinking this thing will be hands down better than most all out there. But watching the vids (which really doesnt mean much) it doesnt seem to move that much air? But we all know moving air entails much more than sub+ box. Shii like amps, electrical, volume, cabin, design... etc. But props to you bro, you took a risk on a new line of woofa(!!) and seem are happy with it!
