Is the Alpair 7 (1st gen) much better than the CHP-70 for mid range and treble? Or the CHR-70?

Drawbacks: the Alpair 7 (and other metal-coned models in this line) can have a teensy bit of "zing" which is great on cymbals, but can annoy the really sensitive listener (but only slightly). Also, they can sound a little "smooth" in the upper treble (to me) and a bit less gutsy and "real" than paper (to my ears).

Over-generalizing, the Fostex are (usually but not always) fussier, more sensitive to the quality of the rest of the system, and can have audible limitations on certain records, but (for me) overall worth the trouble and have the potential to get closer to perfection. But it will take more effort to every part of the system, so is it worth it? For me, lately, yes but I wouldn't hesitate to go with the Mark Audio's and would in fact recommend them to people who want more of that "plug and play" thing.

One last note: don't ever touch the metal cones, and don't crank them up too loud. Oddly, the Fostex sound so delicate, yet can take a ridiculous pounding -- but the Mark Audios (despite the very robust sound) are comparatively delicate and break-able. I've never blown a Fostex but have blown multiple Mark Audio's (not a criticism, that's just how it goes).
"Zing" A bright top end is also a symptom of no baffle step compensation. No driver is plug and play. It is also a symptom of cone breakup.
To keep them alive, be sure to use a real HP crossover.

RWB,

I have not heard the Alp 7 gen1; have listened to Alp 7.3 and to my ears it is superior to the CHR70.2 in midrange and treble. CHP-70.1 being a paper cone is a bit different in presentation of midrange; in treble definitely Alpair is more extended and airy. A driver like the CHP-70.1 will be more forgiving of source and amp compared to the Alp 7 and, and the trade off will be a bit of midrange detail and treble extension. One other quality where I found Alp 7.3 to be superior is its ability to play complex material (vs not only CHP, also other drivers) and the separation of voices/instruments.

P10 and ChrisB should have a lot of expereince with the gen 1 Alp 7 and if they are following this thread maybe they can comment.
