repair and modification of my JBL 4311b
« on: 3 Dec 2021, 11:24 pm »
Hello everyone,   :D

I have the pleasure of sharing my small JBL speakers that I modified and repaired.

I transformed the 2213h into 128h, modified the filter and installed a compression tweeter.
The front layout has also changed with the midrange now found in opposition like the JBL 4412.
I made a little music video to explain the changes.
the sound of the video is that of the JBL captured with 2 C2 microphones, they are fed with a 2x8 W monster Hiraga brought to 2 x15 W with Sanken transistor.
