well ive heard a XXX, and a Brahma...but never an avalanche, and i havent heard any of soundsplinters stuff.
i thought the XXX performed just as well as any W7 ive heard as far as SPL goes, although i actually liked the sound quality of the W7 more than the XXX. but thats my taste, just as everything else in car audio is relative to your taste.
but as things go, the car came with the W6's, and i've been a fan of JL for many years...so it fits my taste rather nicely. there was a used 12W7 on
ebay in a custom box, 1000/1, and a 15 farad capacitor, for 800+shipping. so if you shop around, you can find good deals on anything as long as its slightly used, which doesnt bother me. i also had a friend selling a 12W7, that he had for just a few months (still had warranty), he was willing to give it to me for $275...but when i called him today after work he had already sold it for $400.
i have nothing against RE, AA, ID, or anyone for that matter, i just like JL. i had a set of W0's in some tower speakers in my house, and some W3's in my old car. ive had nothing but good experiences with JL, and theres no sense in fixing something that isnt broken //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
