Eminence Beta-10CX 10" Coaxial Driver
Eminence Beta-10CX 10" Coaxial Driver is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Completely Satisfied!!!I love this speaker! It has great tone when coupled with an APT-50. In fact, the only complaint I had is that eventhough it is called a coaxial speaker, i had to piece it all together by purchasing the tweeter and crossover separately.Once I got it all together though...It is Killin'! I built a 1x10 bass guitar cabinet using this woofer, the apt-50, and the pxb2:3k5 crossover. I put all of this in, get this, a car audio cabinet that happened to be vented and had approximately the same dimensions that I wanted in a custom cabinet.Long Story short, with everything together IT ROCKS!!!

Rated 5 out of 5 by from A GREAT SPEAKERI have a pair of monitors which came with 75 watt speakers and a very small tweeter. I'm a lead singer and I needed more hi-end.I couldn't find a tweeter small enough to fit the cabinets,yet hi enough to fit my personal needs,therefore I purchased the 10cx model to give me the room I needed to add a REAL hi-frequency driver.Now I have a small 250 watt powerhouse.

Eminence Beta-10CX 10" Coaxial Driver

Is this a true coaxial speaker?

What I mean is there 2 separate drivers or just a whizzer tweeter like on older car speakers?
Asked by: Brandonmmmmm
There is a compression driver stuck to the back of the magnet. The sound travels through the dust cap.

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.
Asked by: Toninho
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.

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!
Asked by: Stanwalters
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?

Asked by: dhack
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.
