who cares if the subs hold a spl record?That has little to do with the sub itself.It has more to do with the enclosure,charging systems and most importantly the cab of the spl vehicle.Why would anyone base their sub choices or opinions on a spl system that has no daily real world use?Crossfire subs may hold a record sure,but can you honestly say that your going to go drive in a car with lexan windows and 6 batteries in a 6 cubic foot seating area?Not to mention a freqency response that is totally useless for the music that your whole system was designed for in the first place.Go with subs that have proven themselves to be loud in a real world system.Not that crossfire is bad.just dont buy subs just because they hold a record.Actually JL subs hold a record
too:they are in the most award winning vehicles of any sub in history,And even their low end line has been said to be the best sub for the bucks.Need I say more?
