Amazing driver
Using as a replacement for original Thiel CS3.5 midrange. Just installed today, and even though they need some time to settle and break in, I am beyond pleased. I've used the original mid, a Scanspeak mid, a Dayton mid, and this is by far the most cohesive and honest choice. The music is exactly where it should be, it's precise but not bright, and it adds a depth or dimension that was not there with the other drivers. Very happy with this Fostex FE108EZ. Somewhat coincidentally, the diameter was a perfect fit for the existing cutout. Highly recommend as a replacement for what is an almost-impossible original driver to find in halfway decent shape.

Killer fullrange driver.
All I can say is this driver is worth more then its weight in gold all the way around while playing music. I have used these driver for a while now. I would have to say they are a league above the Reg. Fe series fullrange drivers from Fostex. These drivers also pull out more micro details then any other smaller fullrange drivers I have used. Thanks madisound. Mr. Jeff

This little driver is amazing.
Hello. I had a chance to use a pair of these drivers for alittle while. I can say that they are very fast and very revealing drivers. The drivers didn't seem bright or tizzy. They were very natural and have a very strong midbass. They are very well built and made. It looks like this driver was very thought out and the detailing of this driver is very impressive. This is a step above the Reg. Fe line by night and day. A guy at work wants me to order him a pair as soon as he gets the money. He was that impressed by just looking at that the drivers. jm
