I have an older Dr. Bass 2x12 (I believe it was called an RS212) and recently the horn started making popping sounds. I believe this is the sign of a blown driver. At this point, I may not be able to get much help from Marc at Dr. Bass as the threads in the past couple of years imply that there is real trouble at Dr. Bass. Regardless, I would prefer to change the horn driver myself and I believe I should use one with a higher handling capacity since I apparently blew the existing (I had it dialed in at about halfway). Could someone make a recommendation for a replacement driver/horn for this application? TIA for any suggestions.
