Default "Extended Range" Driver?

Im looking an extended range driver with the following attributes:

- 3" or 4" cone
- 400hz to 15khz bandwidth
- Exceptional detail and "dynamic" presentation
- decent SPL capability
- reasonably low distortion

Any suggestions?

You might like these: http://meniscusaudio.com/images/FE103En.pdf. I've got a pair of FE127's, but they're NLA. This one looks like it might be close, or even better. It might need a touch of taming around 8K, but that depends on your taste. There are a few designs for this driver and similar drivers at p10 hifi | Box Library / Other
Have fun!
Mike

The new CSS VRX126 does a pretty good job of filling your needs. This is exactly the role it was designed to fill. Production seems to have ended up more extended on the top than the protos.

If you are going that way FF125wk or maybe FF105wk (haven't seen it yet) are likely better candidates. Early FF125 work looks like there is some work to be done to clean up the rough edges, but we are at work getting these to fill the void left by the FE127 going away.

And if you are going this way, one also needs to look at the EL70 & Alpair7.3 as well.

The Fostex options seem like decent bang-for-buck drivers. I did have a pair of treated Fe-207's a few years ago. I liked the "fast" presentation and coherency, did not like the distortion and honkiness in the mids at higher volumes.

I googled the CSS drivers but couldnt find much. Are they available yet?

Looks promising, hope to see some specs on these. What size are they? Sensitivity?
