The custom 8" drivers proved too expensive once cabinet production left the US. After they used up existing stock, Fender (who owns SWR) quit building them. My experience with them mirrors Dave's, though for me that was not necessarily a negative. I LOVED doing PA/TV for bands using them because the bass sound rarely did anything unwanted outside of rattling snares. Most players were surprised at that I generally never told them to turn down and sometimes, to turn UP. They wouldn't work for me, but for others who liked them, I can see the appeal.
