EV, electro voice, electro-voice Sentry IVa speakers in very good condition (I would say excellent for their age). SM120 mid-horns with1823M drivers, ST350 tweeters. Dual 12 inch woofers in folded horn. These are super high efficiency and work great with SET amps. I've been using for years in my main stereo. Crossovers have been recapped and everything functions as it should. I've had Klipsch Cornwalls, EV Interface D's, Magnepan 3.5R among others. Nothing compares to the life-like dynamics of a horn system. Being able to drive with flea powered amps is a huge bonus. Easy to biamp and works great if you go active. The SM120 horn and or 1823M driver is a popular upgrade for Klipsch speakers. Sure they're big but they sound beautiful!
