These are very shallow, excellent midbass drivers with an inverted motor setup. They are nicely appointed with hand screw-down terminals that you normally see on higher-end home audio speakers. They have a high sensitivity, are 3 ohm, and have a very nice midrange response. When I purchased them, I had CDT build them with a silver basket instead of the black ones. My pricing is firm. If you have any questions please send me a private message. The price includes UPS shipping to the major 48 USA states.
