both are excellent subs and its really gonna be install dependent on what you're trying to accomplish. What kind of vehicle and what were your ideas on box design?
ive heard both...granted in different enclosures so it is hard to compare. but id rather have the q. Go something different then mainstream, and probably much cheaper....(dunno how much the w6 runs though)
no shit ya i think i might go with the fi Q iv heard so many good thing about fi's woffers and thay are half the price or even less then half the price of anything even close to comprable. Any 1 personlaly heard the btl how is there SQ. Iv heard some strate spl woffers and thay sound so bad with music not much good for anything but slamin test tones
I ran a Q 12" for a couple months in 2.5 cubes tuned to 30 with right around 1200rms going to it and it sounded beautiful,the way it caught the lows so loud and clear it was amazing but it just didn't have the output I crave(150's)
