Look Inside Upgraded JBL E100 Speakers

Look inside and teardown 3-way JBL Northridge E100 upgraded floorstanding loudspeakers. The JBL e100 speakers are modded for around $800, upgraded midrange driver, audio crossover and enclosure box. Disassembly modded JBL E100 and find out why these speakers sound so powerful. To power up these JBL speaker in bi-amping, I use Kenwood KA-660 stereo amplifier for bass and Pioneer M-73 for mid and high frequency drivers. Sound source is Topping Dx3 pro USB DAC.
