1. Can you still buy the old RE XXX 15" from RE? 2. If so, What will hit louder in a 4 cubic foot box tuned to 32 hz powered by an RE 12.1 the SX15 or XXX15? 3. Again if so, is it worth buying a brand new (old model) XXX, then selling my SX15? 4. How much does the old model XXX15 cost? 5. Would it have to be dual 4 ohm or dual 2 ohm to run at 1 ohm????
1.no 2.SX...spl geard sub 3.If u want an improvement in sq, the XXX still gets really loud.. 4.Check ebay..and online 5.and dual 2 for 1 sub..like Dan said
