Eminence Beta-10CX 10" Coaxial Driver
I am planning on getting a pair of the Eminence Beta-10CX co-ax drivers and wanted to know whether the Eminence ASD1001 horn driver is compatible with it, and as to what cross over I should use. If the ASD1001 is not compatible, what is ?
Yes the ASD1001 is a compatible driver. I would recommend the crossover below as a good option.http://www.parts-express.com/eminence-pxb2-2k5cx-2-way-speaker-crossover-board-2500-hz--290-635

do you need to install a dedicated crossover if you use an APT 50 super tweeter? What happens if you don't also install a crossover? I'm using this for a guitar cabinet. I'm replacing a Beta 10a because I need more high end.
Yes there will need to be a crossover for any compression driver you attach to this woofer. If you do not use one, the driver will likely be damaged or fail due to being over powered. If you are planning on using the APT 50 tweeter, the crossover in the link below would be ideal.http://www.parts-express.com/eminence-pxb2-2k5cx-2-way-speaker-crossover-board-2500-hz--290-635

Does it fit in the 10" subwoofer cabinet. http://www.parts-express.com/dayton-audio-swc-1co-10-cu-ft-subwoofer-cabinet-with-cutouts--302-802 1cu ft.
Unfortunately this would not be a good choice for that cabinet cutout. You would be further ahead using the blank cabinet and cutting your own driver cutouts.

Will the ASD1001 work?
I see that it is common to use the APT-50 HF driver with the 10cx, though I can't seem to find the source of this recommendation. Is there any issue with using the (better?) ASD1001 instead? If not, what would the recommended crossover be for that setup? Thanks!
That is a very good match. The ASD1001 is very efficient and LOUD. Great high end as well. Some drivers are rated above 10K but that is with a fast roll off. This one is a true tweeter driver. Crossover is about 3K to 3.5K. This point, matches the woofer well. A great value as well.

Removed from the APT 50 tweeter, what is the highest usable frequency of the 10CX?
Figure 3100hz on the upper end max. If you are crossing it over, do so around 2K at 6db/oct. You can go up higher but will want a steeper slope to avoid beaming and anomolies in the response curve.

What would be the minimal and also optimal sealed enclosure size? What if ported and what tube?
I am looking to build a custom monitor for 100 Hz and up. I need a very natural and smooth response. The APT-50 Super Tweeter would be added. It would be bi-amped with an electronic crossover plus amp. This would be for a permanently installed stage monitoring situation; acoustic instruments and vocals mostly. Hence, I don't need much bottom end.
A sealed enclosure of .98 cubic feet would give you a Q of .7 and a F3 of 89hz with a linear taper from -6dB@ 67hz down.Reducing sealed enclosure to a minimum of 0.6 cubic feet keeps you approximately linear above 110hz and gives you an F3 in the mid 90s. Smaller than that enclosure size would not be advised, Q is already in the high 80's here.If you choose to go with a vented enclosure, 2.0 cubic feet with a 50hz port tuning frequency keeps you very linear down to 60hz and keeps phase coherent (identical to "sealed" phase) down to well below 80hz. F3 is right at 50hz and at 40hz (low E on a four string bass) you're at -9dB. Not bad. If you do two, 3" diameter vents 4.95" deep with at least a 1/16" radius roundover at each end, you'll be in good shape.
