Usher Domes come without the back plastic piece that was removed due to the resonance/vibration heard when in use. I just threw them away since I didn't think I'd ever sell the driver and it sounds best in its own seperate enclosure anyhow. Basically newish condition. Selling for $100 plus shipping. These sound phenomenal and I wouldn't hesitate to put them up to just about anything out there. I've got the Seas Excel craving again and will use the W15 instead. Domes will ship in original packaging.
