Very Nicely Done Speaker--Great for high powered Vibroverb conversions of Twin Reverb type amps.
SINCE the usable frequencies of a guitar are right in line with this speaker and its dB sensitivity makes it very powerful sounding but tight--not flabby at all. The only thing missing with this speaker is a aluminum voice coil cap and it'd be vintage 60s/70s. The speaker really moves air like the old JBL cones--but not flabby on the bottom end or overly bright needing a diffuser--ala some D-150s. Was amazed at how nicely this worked in a 120 watt tube amplifier. I'd buy again if it had just a tad more top end (aluminum cone cap). Really nice speaker.

Love this beast!
This thing ROCKS! With it's 6.7mm of xmax(excursion) this thing acts like an high efficient woofer. I have this woofer in a 6.1 Cuf3 cab, vented, tuned to 36hz and it sounds amazing! VERY clean, punchy, and plays all the way down. If you keep a steep lowpass around 30hz(to protect from over excursion), this thing WILL handle 300w+ all day long. The 4ohm impedance is REALLY nice for matching amplifiers. Having 4ohms instead of 8ohms really helps in getting more power from your amps. It helps to save you money, not having to buy larger power amps that will push a higher wattage at 8ohms.
As far as using it in a 'full range' setup, I have not tried, and it's really not designed for that. This is a true "subwoofer" and it's upper frequency roll off proves that.

This thing is a monster.
This thing is a monster. Use the specs on their website to make a box. Reinforce the crap out of it becuase this thing will tear your box apart if you don't.

I purchased two of these looking for a exact replacement to legendary EV10M for my car audio installation and I must say I compared side by side to my EV's and this speaker has the quality sound that we love. Made in the USA

I feel like I just bought a whole new stereo system
I received my Delta Pro-15As on Sept. 28. I installed them in my existing home stereo system on Sept. 29. I feel like I just bought a whole new stereo system. I can't believe the difference in the midrange and bass. I needed a high sensitive speaker for my 2 watt SET tube amp.
It kicks. CH

This is a terrific woofer.
Replace a Bag End woofer after 20 years with this. Almost wish I had blown it years earlier. This is a terrific woofer.

12" PRO WOOFER; 800W MAX; 8 OHMS
This is a wicked speaker,I was looking to get another EV-12L for my 2x12 cab. Had been playing it for a while with a couple of pillows taking up the space..lol.. After looking around at what else could hold it's own, beside the EV-12. I ran into a guy that had a Delta Pro 12A in his Mesa Thiele cab, and it had such a great fat bottom end I knew it wasn't a EV-12L that usually is what guitarist use in that cab.
Well after talking a while with the guy,he said he had swapped out the EV for the Delta Pro and fell in love!! And I know now just what he meant!!! Pairing up the Delta with my EV is pure magic, the EV shines in the upper register while the Delta fills in the lows and mids so well it's stunning! I've used this setup with everything from a Blackheart Little Giant 5w to my Marshall MF350 monster and these two rock together like no other speaker combo I have used. With head room for days,and I'm 3'' shorter from lugging this 2 ton beast around.

This driver has awesome sound. Also the build quality is immediately apparent. I installed it in a Carvin 12" powered floor monitor, 400 watt, and it vastly improved the sound quality.
