What is the best sub out of these three: JL Audio w7, Fi BTL, or RE xxx?

Money is not a factor, but how much would each of them cost? I want the best in sq and spl. rank them each on a scale of 1 through 10 (10 being the best) on sq, spl, and overall.

and what amp should i power them with?

The RE XXX without a doubt. The FI could be louder maybe. But, the XXX is like King of subs. They weigh 78 lbs each. JL W7 might yield the best sq but wont be near as loud as those other 2. The RE and FI both rms at 2000 watts if I’m right and the JL W7 rms at 1000. So twice as much power is needed for those two subs. If it were me I would go with the W7 because I am more of an SQ guy. Also you save tons on amplifiers, big three, caps, alternator, battery.
Hope this helped.

   Well, you have 2 Sq subs listed and a SPL sub in the middle.

   The RE XXX is a heavy sub. It is actually a heavy POS. They are very inefficient, have horible motor noise, and just cost too much. They are far from a great sub. when Scott owned RE, it was a great sub. Noe it has been changed and horrible.

   The JL W7 is a better quality sub than the XXX, but you are again talking about a pure SQ sub. Anythin above 45hz these subs lack and lack hard. They would be ALOT better off sticking these in a home theater application.

   The Fi BTL is a good sub, but SQ isn’t great. Sounds ok, but still doesn’t pick up the lows like I would like.

   If you want real help, shoot me an email and I can help you out.
