CSA Diaphragm for JBL 2412, 2412H, 2412H-1 -- 8 Ohm

Circuit shop is one of the few stores on Amazon where you can buy these and they do deliver. Got these to replace originals in JRX-115 we have been using for over 6 years and burned out. Replacement was very easy (online searches will give instructions) and they do sound really sweet in layman's terms; do we need to get into frequency roll-off and transient harmonics? One thing was noticeable was the lack of metal. The factory diaphragms were metallic discs which in my opinion were better for heat dissipation but that's IMO. JBL knows more about this than I do so let's see how long these would last.

Installation was a snap. Is not made of metal like the original, but could not hear any difference between it and the other 4 identical cabinets that I own.

I bought this replacement hoping that it would be a good replacement for the JBL diaphragms that had been burned out. What I found was that these are ok but won't take anything out of line the first one blew the first day. I ordered another one which made three all together and so far it has held up. I would recommend the more expensive metal ones if you have a live band situation.

Replaced both diaphrams in our mains and they blew one hour into band practice. I wondered why they were cheaper than the others.

Installed as they arrived (pair), been using them for a year... no issues whatsoever... perform almost like the originals from JBL.

Good, reliable, low cost product. Sound was excellent, clear and crisp and easy to install. Shipping was fast as well!
