You should definitely ditch the type R's for some Type X's! I had two of them running on a 2000 watt amp but had it set to a sql setting for when I just want to listen to some good tunes, but also when I turned it up I could wake up the dead. They put out like 15's do, just with have the space and twice the amount of accuracy. Got a pair on ebay when the first came out for 250, the price at 499-599 each. Just a suggestion, but Nice setup!
