Good value. Not the best sound but not bad. I used it for a boombox and sounds much better than a similar price full range.

Great tweeter for the money, combined them with a 6 1/4 speaker to build a nice set of book self speakers. Sound is clear, and smooth, not to pitchy or screechy like some cheaper tweeeters. Certainly not high end but very good for a moderate build.

Both tweeters stopped working in my circa 1991 JBL 2800's. Just put a pair of these in and they sound great. Listening to the Who at substantial volume right now and all's good. Magnet is about 2.75 inches so had to modify a bit to fit as well as notching for terminals. Great 8 ohm replacement tweeter.
