1 Toxophilite 2 weeks ago I have a vibrolux reverb i built. 30-35 watts. Do you think it will kill a pair of 1961 Jensen P10Rs in apparently good condition(out of a hammond chord organ). Generally if I come across pricey vintage speakers for a deal...I sell them and use modern ones. The rational being these are 50 year speakers and likely a little fragile. Also the sound people prize with these speakers was usually captured when they were new..not 50 years old. However they weren't too much Do those that know think a 30-35 watt vibrolux will kill them? If played mostly clean? That is keeping the amp within it;s intended design parameters.
