Eminence Delta-12A 12" Driver 8 Ohm
Eminence Delta-12A 12" Driver 8 Ohm is rated 4.7692 out of 5 by 13.
Rated 5 out of 5 by from Best Speaker for Bass CabinetsI've built a couple months ago a cab with this speaker and by far has the best spectrum sounds you can get in a 12" speaker without a horn/tweeter. It gives enough low end frequencies and clear high end, crispy notes not top mention how ridiculously loud this speaker can get! I've actually sold my cab due to financial hardship and regret it big time. I also have built another cab with the Delta12LFA and it sounds dark with very low response on the high end frequencies.If you replacing or building a 1x12" bass cabinet without a tweeter this is the best speaker you can get in the market right now. Stay away from the Neo drivers... Those speakers does not gives the natural tones a bass amp should produce.

Rated 5 out of 5 by from Pound for the ounceSome of the best pound for the ounce speakers I have used. Tight, heavy responce. Used in conjunction with 12" omegas and cover exactly the sound range I wanted.

Rated 5 out of 5 by from Performance and ValueA solid speaker at a very fair price. I use it for mid drivers in my PA. 90 hertz up to 2.5 kilohertz.1800 watts to a pair for 4 years without a failure. I always get complements on my sound.

Optimum Cabinate Size?

what would be best to support bottom utilizing this speaker as a sub? Thanks for the help.Larry
Asked by: Larry10
In the information area on the product page - download Eminence Delta 12A Suggested Cabinet Design. It's a good starting point. From there, if you don't like he resulting performance - you can use a box calculator to see other options. Often - you will have a goal and after using a box calculator will find that the driver you want doesn't fill the bill. This is where you do your homework.. Have fun !!!
