Eminence Beta-10CX 10" Coaxial Driver
Eminence Beta-10CX 10" Coaxial Driver is rated 5.0 out of 5 by 7.
Rated 5 out of 5 by from Very nice.I built a very small coaxial floor monitor using this driver, the ASD1001, and PXB2:2K5CX. Sound is very smooth, needs very little EQ.Cabinet design is similar to the EAW MicroWedge with the curved back and Speakons recessed in the front. This is a sealed cabinet.

Rated 5 out of 5 by from Truly a GemFor the price, you can not do better than this driver for its intended application. Typical Eminence bullet proof construction and married with the proper CD, this thing is loud and proud. There was some discrepancy in the SPL specs, so I popped a quick email to Emi customer support to verify. The actual efficiency is 94.3dB, NOT 95.1, so keep that in mind if you need to construct an L-pad for your CD. I bought 8 of these and they do not dissapoint.

Rated 5 out of 5 by from great all around speakerI bought this a few weeks ago and it exceeded my expectations. Great low end. Mids and highs are ok but I got tweeters that fill in that void. I replaced a fisher speaker in a fisher cabinet with one of the 10 in models very very pleased.

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.

Rated 5 out of 5 by from JAMSI have four of these in my room two in each speaker and it is so loud i knock pictures off the wall and other glass objects.

Eminence Beta-10CX 10" Coaxial Driver

If using as a woofer only, will the threaded hole for the compression driver need to be sealed for proper cabinet porting?

Asked by: Sponge
Yes. The driver comes with tape that plugs the hole, but this may not be enough to seal it properly.

i only see 1 driver in your picture, how is this a coax? and if it is is there a crossover built in?

Asked by: jalang
This driver has an acoustically transparent dust cap and a 1-3/8" 18 TPI threaded pole piece for a screw-on type driver to be mounted to the back. These do not include the high frequency driver.

Would this be a good replacement in the Idol Pro IPS 550 series speaker? I have two of them that the suspension foam badly coming apart on.

Asked by: JDUB Sings
We do not have a cross reference available for this type of thing. Please contact our tech support for more help with this question, or 800-338-0531 x1.

What would you recommend for home use (HiFi/Surround) to this, the APT50 or the ASD1001? From the specs it seems like APT50 is a little smoother but the ASD1001 can play louder and lower frequency so I can put the crossover frq lower?

Asked by: optimistic
The ASD1001 is the driver intended to compliment this woofer, but any standard threaded mount driver will work. We do have a pre built crossover that is made for this combination.

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 ?

Asked by: AVKESQ
Yes the ASD1001 is a compatible driver. I would recommend the crossover below as a good option.
