The JL w7 series far from sucks. I am a big JL Audio enthusiast and I've heard a lot of sound systems (most of them JL). The W7 has some of the tighest bass.. it delivers awesome SPL and SQ for 1 10" woofer.

But two 10w3's will rock too, and if they come with a box.. I'd say $200 isn't half bad.. though I would definitely try and lower the price if possible.

The w6 series is definitely a great alternate to the price of the w7 series. I am personally going the new 12w6v2 route in my car. They have awesome SQ/SPL. I would not diss on Eclipse subs either, however, I must say JL makes a great product (no I don't work for them).

Btw.. if you buy anything off E-bay and you are not given the dealer's receipt that the sub was purchased from.. I believe the warranty card they may or may not give you is a complete waste.
