Just picked these up from the local audio shop. Now I'm trying to find some information on them but can't find any. I'm trying to decide if I should go ahead with these or get Alpine Type R's, spr-60c, for almost half the price(Currently $150 shipped on Amazon). Reviews seems mixed for the Type R's here. So far I have an Alpine PDR-F50 4 channel amp(birth sheet rates it at 162w @ 2ohms and a Kenwood Excelon KDC-X997. Planning on getting 2big4aS2000's box w/ the memphis sub. Any thoughts/opinions/input please.
