The P8R is a great little speaker, but a bit over-priced in my opinion. A very nice sounding 8″ alnico that you might want to try is Weber’s “alnico Signature 8” (not the 8S…it’s harder for the 8S to break up under the Percolator’s output wattage). At nearly half the price of the P8R, i think it sounds as good or better in some cases…https://taweber.powweb.com/weber/asig8.htm
UPDATE:Given our spidery connections throughout the music manufacturing industry, and our awesome buying prowess, we recently learned that we here atZDL can obtain the Jenssen P8R for about the same cost as the Weber Signature 8. If you wanted US to perform the upgrade, we could install either speaker into either the 1×8 cab or Combo for an upcharge of about $70.
