well arc audio could answer that question for ya... //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif but the reason is that one came looking like it was damaged before shipping... there were about 10 small dents in the center cap, scratches on the ring around the subs, and the packaging was missing from the box... i had asked previously multiple times about the condition of the subs and they were stated to be brand new in box... since arc is no longer distributing/marketing rainbow (alumapro is now) they dont have any left to send as a replacement... so im just getting my money back because i need a pair of them...
also... just heard an idmax in a 2.5cu ft ported box running off a hifonics brutus and wasnt too impressed... dont get me wrong... it sounded good but i dont see what all the fuss about it was... maybe i just need to hear it in a different setup...
