Eminence Beta-15A 15" Driver
Eminence Beta-15A 15" Driver is rated 4.6 out of 5 by 15.
Rated 5 out of 5 by from Great woofer!5 years ago, I built 8 sealed 2 way stage monitors using the Eminence Beta-15A woofer and the Eminence ASD1001 Compression driver. Crossover point is 2.5k. This turned out to be a really sweet sounding combination for me. I have been able to drive the Beta-15A to its full 300W power rating with no problems. The overall bass response was surprisingly good for a small sealed cabinet (about 1.75 Cubic feet). I can send some bass and kick to them, and they will handle it all night long. I love it so much that I plan to buy another set of 8 woofers to build more stage monitors. The Beta-15A is a pretty versatile woofer that works as a drop in replacement for some entry level to mid level PA cabs. I have also had good luck replacing the woofers out of the JBL JRX series cabinets with this woofer. Get these, you won't regret it!

Rated 5 out of 5 by from Perfect for My Open BaffleBuilt a set of open baffles with these. One a side and these are exactly what the doctor ordered. Smooth and delicate. These make the string bass sound like it's in the room. They are rolled off at 6db at 200hz, seeing 300 watts, a subsonic at 40hz and could probably be crossed higher than 200hz with zero issues. I highly recommend these. I've read some complaints about a lack of low end authority, I don't have that complaint. Low end sounds tight, smooth and very musical. If I need more that's what I have a separate sub for, of which I find myself turning down more and more as these get broken in.

Rated 5 out of 5 by from Great replacement speakerI had these in 2 single 15" scoops. Sounded good until I turned them up one day and 1 started crackling. Turned out to be an amp problem that hurt the Beta. The one working beta and the new one I bought today are going into an old Audio Centron Cabinet with an Eminence Horn and Beyma Tweeter and Eminence 3-way x-over. The one working cab sounds great. cant wait to fix the other

Rated 5 out of 5 by from FCWCWhat can I say.Lovely drivers for the $. Though I purchased these units for a specific enclosure. They are versatile and can work as a drop in replacement for just about any enclosure.

Will this be suitable for a bass guitar cabinet about 4.75 cu/ft with 2 round front ports?

Asked by: RufusKhan
This will theoretically work but for the same price you will get much better response out of the Legend 15" below.http://www.parts-express.com/eminence-legend-1518-15-guitar-speaker-8-ohm--290-496

Beta 15A for 2-way or 3-way speakers? Based on the frequency range this driver could be used in a 2-way setup with a horn or a bullet tweeter crossed at 2.5K or 3.5K. I was just thinking if it would sound better in a 3-way setup.

Asked by: Joosoof
Yes this will work fine for a two or three way speaker system. I usually don't recommend crossing a 15" driver higher than about 1,500 Hz however, so you will need a horn that will handle a lower crossover point than 2.5 or 3.5kHz.

Will this work in a small cabinet?

I am interested in replacing the existing driver in a TC Electronics BG250 Bass amp. I estimate the box to be 2.7 cu.ft. with a shelf port 14x2.5 inches.
Asked by: Swampgas
I would not recommend a vented enclosure that small for this woofer. It would work well if you wanted to seal up the cabinet however. In order to keep it vented I would recommend part number 295-034.
