Yeah I know W7s and L7s aren't really in the same class thus it is hard to compare them but there is a big debate of which is better. Basically what I am getting from this is L7s gernerally get louder but W7s usually have better sound quality and sound better on the lows depending on the setup of both type of subwoofers. If I had a lot of money to spend on subs, sure, I would spend the extra money on W7s. But honestly, I think L7s look way cooler and get just as loud if not louder. Sound quality can always be made up for with a nice box, amplifier, wiring, etc
