um i wouldnt say 7500's are bad if you want a spl subwoofer out iof those i would go with the 7500 and i would say that cause i own them and have heard the others but personally i would buy the w3's cause they sound beta and get loud
i'm sure the new w3v3 will be more expensive than the w3v2 if you want to save money go w/ the w3v2's. i can't see that there is going to be a night and day difference between the v3 and v2. at least i hope not since i have 3 w3v2 and have only had them for 7 months
W3 is a good choice but just as common as a Type R. I would go for a SS RL-p or ED Ov.2 series. Or wait on Nick to get the BM Series from Stereo Integrity, if it keeps with Nick's perfectionist attitude it'll blow away mid level stuff.
