FR88EX

Fountek · 27th December 2010, 02:00 AM

I want to recommend one full range driver named FR88EX here.

The motor is an underhung neodymium design and the cone is thin (and fragile) formed aluminum. The only negative is a slightly ragged top end that may take some filter work if used full range, but I'd generally recommend a cheap and small neo tweeter placed close and crossed over high. There's a lot on the positive side, like high sensitivity, a clean low end and smooth midrange response. The frame is cast with ventilation under the spider, but users will have to pay close attention to airflow behind the cone - It's even more important to chamfer the inside baffle opening and in this case likely use a thinner baffle material as well.

Thanks Evan - looks like an interesting driver.

I have a friend who will be using this in an open baffle design with an 18" woofer under it.
The design may be posted on diyAudio if it works out.
