i have 2 10w6v2's powered by an Audioque aq1200d in my SQ setup (which I just finished out this weekend actually). i picked up the speakers second hand from a person that only ran them for 10 hours of play and didn't like them. the reason he didn't like them is because he bought loud SQ speakers when what he wanted was SPL. if you are after great SQ in your sub bass performance you would be hard pressed to find a more satisfying sound. if you want loud but still musical speakers i would look elsewhere cause you can get much better speakers for way less for that.
If you are after SQ then I would consider those or maybe the Fi Q's. The AQ1200D has been an excellent amp for these subwoofers so far.
they are sealed. IMO it is the only way to go with enclosures if you are looking for sound quality. the AQ amps are quite amazing. when i bought it i really had trouble believing that they would do rated power with the price tag (250 bucks shipped is very nice for 1200wrms). 2 jl 10w6v2's also get louder in a sealed box than i would ever want/need too with that amp. but still they are for SQ so loud really isn't in the equation.
I agree. The JL W6's are very pricey. The Fi Q was actually what was going into my car until I got a good deal of the JL's. If you can find them for a good price on eBay I would say go for it. However, the Fi Q was another sub i've heard great things about when considering SQ and were actually my first choice because of pricing.
JL makes really nice products, the W6 is arguably the best SQ sub out right now. Unforunately, if you buy it online from a non-authorized dealer, the warantee is void. And if i were paying a few hundred dollars for a sub, i'd want a warrantee.
Now, IMO 480 is too much. My buddy got his 13w7 for 700 authorized. Try to talk the shop's price down, but if you can't i would look into a pair of Boston Acoustics G5 subs. They are extremely close in SQ when compared with w6's, but you can get one 12 for about 250.
That being said, if i could choose any pair of subs to put in my car, they'd be w6's. bar none, they are my favorite sub, incredible sound quality while still bumpin'
