I have 2 Eminence Tonkers at 16 ohms and 150 watts. Used them with a Hiwatt as they are infered to sound like a Fane. switched them over to with a Bandmaster Reverb though they sounded best with SF BF Fenders. Clean warm sound and not spikey. Gives a 2x12 the power to take on a 100 watt amp and not sweat it. There is a scratch on the label but otherwise mint.
