JBL E140-8 15" Bass Driver, sn 75128 SOLD OUT

This driver is one of a pair that was purchased some time ago for a customer's project that has been abandoned.   This driver is in Very Good condition. 

The E140 is the successor to the very powerful and popular D-140, which was used extensively in low frequency cabinets for Bass guitar, Organ, Synths, and subwoofers.   Somehow, JBL managed to improve on the D140 with its replacement.  

Here's some information from JBL:

El40 380 mm (15 in)
The El40 is specially designed for the bass guitarist or keyboard player who wants a bright, sharply defined sound.  Bass notes are projected with an incredibly strong punch, and overtones are crisp and clear. The El40 is capable of producing extremely high sound pressure levels with efficiency that’s unmatched by any other bass speaker except our own El45.
