Default Driver Suggestions for 7L Cabinet - Finished!

Hello All,

I been wanting to experiment with full rangers. I have a little Fostex Kanspea kit and I love it. I also happen to have some Parts Express 0.25 cubic foot (7L) cabinets that I was thinking of purposing with a fullrange driver.

Any suggestions on a good driver for this enclosure? I't be sealed and paired with a sub and AVR with Audessey XT. I'm thinking a CHR-70 or Alpair 7 from Mark Audio might be a good fit. Any ideas would be welcomed.

Of the ones i regularly play with:
Mark Audio CHR/CHP70, Alpair 7.3, maybe sealed A10.x (i'm guessing on the A10s, i'm not not in a place to access my sims)
Fostex FF125wk, a bit big for FF105wk.
In people's closets, CSS FR125, EL70.

Thanks Dave. Is the Alpair 7.3 really all that better than the CHR/CHP-70? Also, I've seen reference to the CSS EL70 but I don't see it for sale anywhere is it NLA?

Yes, the Alpair is that much substantially more refined than the CHR

Too bad about the EL70 - for years my other favorite driver by Mark. While nominally same size range, the new CHP70 is not cut of quite the same cloth.

Rumour has it (or does now ) that a new 70mm paper driver is in the works, based on the Alpair 7 - actually I think prototypes have been produced and maybe even shown here. However, until T/S parameters are known, it'd be silly to speculate on required enclosure volumes / tuning.

FWIW, I've heard the A7.2 and .3 in a fairly wide range of enclosures, but all of them vented one way or the other. Dave or others probably have modeled curved handy that would suggest approx LF roll-off in a small sealed enclosure.

You might want to look at the Faital Pro 4FE35. Comparable performance to an A7.3 as measured by BMS. Maybe not quite as much on the top but appears to be a good performer and is priced well. On the downside it looks very industrial and can use a grille.

Yes, at least that much.

Wow, the 10.3 would crossover almost perfect with a sub. I'm guessing the 7.3 would just be a higher crossover point that might lead to localization of the sub? Thanks for the all information.

The A7.3 looks to be pretty close to the A10s sealed in that volume

Looks like 7 or 10 is the way to go. Leaning toward 7 because I know it will fit. The baffles aren't really as wide as PE says because of the internal bracing. I barley fit a 5.5" woofer on one last time. Thanks again for the recommendations. Have a good weekend.
