The OHM L2 upgraded woofer kits offer smoother transition to the low tweeter and use a new foam surround that is projected to last up to 30 years that will allow for more clarity on female voices. The FerroFluid cooling handles the thermo transients from CDs.

"I recently bought replacement woofers for my L2's. It had been years since I had heard hem. And maybe had forgotten what a speaker should sound like. I do have many other pairs of speakers but the L2's. They are truly amazing sounding. couldn't be more pleased with the quality of sound produce over the complete spectrum from lows to high. I have been a musician for over 30 years.

"When I play piano, I play my Steinway.
When I want power, I play my early 60's Les Paul Standard through a Marshall.
When I want clean, I play my early 60's Telecaser through a Fender.
When I want rich, I play my Gibson ES 335. With my Fender.
When I want to sit and listen to music, I play through My Ohm's.
THE WAY MUSIC SHOULD BE HEARD!!!
Thanks to all"
