My friend used to work for a theatre doing musicals, and they were cleaning house so he was able to acquire these for nothing and was using them as a table in his garage not realizing what he owns. I have never felt the drums in rock music the way these kick me in the chest, and the stage is huge. Sealed dual 6.5” woofers and a 10” passive radiator with a 1 inch metal dome. I’m going to miss these very much when I have to return to my little Focal Choras
