Who makes this driver?

[audiophile36]

It's a 4" paper fullrange driver with whizzer cone and foam surround,has a double magnet and reads 9930/9900 8ohm 15-30W.I have them in my test boxes and they seem pretty effecient and have great high frequencies.I found them in a set of KLH plastic hometheater speakers....does KLH really make them or are they out sourced?

Looks very similar to a Visaton FR10.
All specs, weight etc are given here so you could compare:

There´s more than one version of the FR10 BTW.

Thanks for the link Joensd. They have nice drivers (on paper anyway)

Thank's for the link.They look just like the Visaton FR10 except they seem way more effecient than 86db.

From the appearance alone it looks like the Linear Reasearch 4" duel cones I have might be an offshoot of the Visaton FR10.
