[QUOTE="zako, post: 7880686, member: 629735"] No, the ones I mentioned are SWR-843D/823D. These are from the previous generation Type-R lineup. Alpine didn't update the 8 inch model when it released the 2012 line-up for 10 and 12R, so those 8Rs are effectively "current generation" Type-Rs as far as 8 inch subs are concerned. They are not SPL monsters. Their power handling is 350watt RMS a piece, and you don't want to exceed that. Someone reported that they start to smell funny past that.
