I saw a thread here recently about JBL 15's and I was very interested to see that the E130(?) has an exceptional SPL of 105dB. Very handy for older low-powered amps like my Jansen 75 or Selmer 50! Do correct me if I am wrong, but the E130 is not being made anymore and is expensive to re-cone. Is there a current production 15" driver with similar sensitivity? I've also got a late 1960's Jansen 2x12 cab that I'd like to replace the drivers in - any suggestions for 12" drivers with similarly good sensitivity?
