these were standard equipment in Laneys and some Hiwatts in the 80s. They're not loved like the Medusa but they're more like a 70s Fane to my ear. Sensitivity is close to a greenback for pairing... a very full sounding speaker. Balancd tone, smooth overdrive.... to me the Medusa has too much handling and is more like an EVM12L. Good for someone. This guy is more my bag. Also pairs well with some vintage JBL Alnicos that have lower sensitivity ratings. I was using these exensively for a while but now I just have one of them in a cab I don't use much pired with a JBL. They're pretty loud watt for watt with a lot projection and can be fussy to record at home.
