Rated 5 out of 5 by from Piezo replacementI used this to replace the kustom 15 piezo and everything sounds clearer and brighter. Power rated at 60 watts - i cranked them up and no troubles with a 200 watt powered mixer. Worth it pick them up.

Rated 3 out of 5 by from Good back up driverThis is a driver that is a good back up for a low level or entry level monitor horn. It does have a reasonable quality and I would not hesitate to use it again.

Rated 2 out of 5 by from Emergency replacement tweetsI'm a sound guy here in Chi-town for several bands, I bought these for emergency purposes. In case I blow out a horn during a gig. I have several JBL SR & MR series cabs. At $120.+ for diaphragms, I can't afford to keep back-ups on hand. So, I have a pair of these to switch out at a moments notice. I know, their piezos. But in this economy, try having 2 or 3 JBL spares lying around. I have yet to use them, but I know I won't be disappointed or embarrased at a gig. In the meantime, I then order the JBL.

Rated 1 out of 5 by from Big nothing.If you put enough power into it, you can get a high pitch screech and some radio stations. Otherwise it puts out about as much sounds as a pair of earphones. I found a better 2 inch tweeter at a local pawn shop for $0.99 and went with that instead.

Rated 4 out of 5 by from A very loud Piezo - waddya want?...This tweeter driver does exactly what it shyould - it plays very loud. It is far better than a typical piezo, but remember, it IS still a piezo! These usually sound extremely harsh due to people running them with no crtossover, and attaching them to a large throat horn. Here's my secret - even though it is technically a "plug & play " (no crossover needed) driver, USE A "REAL" CROSSOVER WITH IT! I'm using a 12Db /oct at 1800Hz. It is attenuated down -3db relative to the woofer, and is running 180 Degrees out of phase relative to the woofer (Woofer is an Eminence 15" PA speaker). Remember, this isn't a high dollar titanium driver - it's a piece of plastic - but overall it sounds great if you take the time to tweak it correctly.
