looking for a high Q 8" driver

[kan3]

like the topic stats

8" driver
high q design...perferably high .5+
decent x-max of 3-4mm+
decent sensitivity of high 80s+
3.5" or small mounting depth

$50 per driver is a nice starting price range i suppose

right now i was looking at the eminence alpha8 partsexpress has them for $34 a driver in a set of 4

Maybe this one?

MCM 8" Poly

According to Pjay's driver finder this one's Qts is 0.72.
It's perfect for paralelling with its 16Ohm rating. And the price is right also- around $14.00. Personally I was considering it for a dipole project.
8 per side in a series/parallel configuration for a nice 8Ohm rating with high sensitivity.

dang i like everything about that driver, but do you happen to know the mounting depth? this is extremely important

it doesn't look like its over my limit but pictures can be deciving

 

[Thunau]

No I don't know its depth. MCM has a Tech Support page where you can request additional information.
I suggest you start there.

Is the driver you're looking for going in a car?

Kan3:

Thanks. But he lists these drivers by F3, not Qts. Is that true, or am I missing a page off this website?

Paste the data in a spreadsheet and sort by the Qts column.

A little higher price than you wanted, but a lower Fs than you were hoping for, plus a better Xmax and it suits your depth requirements, (3¾"). Or did you require 4 ohm?

[kelticwizard]

Xmax is a little less than you wanted, but it is 4 ohms for the car, the depth, (Parts Express' "C" dimension), is right at 3 5/8" and everything else checks. Plus the price is nice at $13.

Another nice one, seems to fit all your requirements. Price is $29. Available in 4 or 8 ohm. Depth is 3 11/16"

All in all, Parts Express is selling a lot of *" woofers, especially Goldwood, which would seem to have both the numbers, the depth and the price you seek.

It's discontinued, but the Audax AP210MO would also look good if you can find it. It's listed at $32.

Good luck!
