It appears the JBL 2012 has been discontinued. Has anyone tried the replacement and is it still suitable for the Pi midhorns?

I was thinking of buying a pair of 2012's, especially if someone knows of a place that has a decent closeout price?

Thanks, Ian

I've tested only the JBL 2012 and Eminence Alpha 10 and Delta 10 drivers in the midhorn. Each of those sound very nice. If you can get a good price on 2012's, snatch them up. If not, don't worry, the midhorn sounds great with a Delta 10 too.

The best price I found for anyone with stock was jblpro.com's B-Stock for $240, which doesn't seem like a great deal for B-stock.

I was looking at the specs, and they seem to indicate that the driver has less than 0.1% distortion(over 30db down) over most of the range its used in the midhorn. Am I reading that correctly? If so, thats quite impressive.

The JBL 2012 is a very nice driver, as are all the JBL Professional Series woofers and midrange drivers, in my opinion. However, distortion products that are 30dB below the fundamental represent 3% distortion. That's a pretty respectable figure for moderate to high output levels in the middle of the passband. Here's a dB - percentage conversion chart:

-60dB = 0.1%
-55dB = 0.2%
-50dB = 0.3%
-45dB = 0.5%
-40dB = 1%
-35dB = 2%
-30dB = 3%
-25dB = 5%
-20dB = 10%
-15dB = 15%
-10dB = 30%
-5dB = 55%
