Eminence Deltalite II 2512 Neo 12" Speaker Driver
Eminence Deltalite II 2512 Neo 12" Speaker Driver is rated 4.2222 out of 5 by 9.
Rated 5 out of 5 by from Light and Mighty WonderI have many speakers, guitar amplifiers and cabinets. I bought the 2512's , to test them against the Eminence Delta Pro12 A model. When I originally got them, I compared them to the pro 12A and found them similar but less bass and slightly more midrange and very clean. My test amp is a 77 Fender Twin Reverb, modded to 1963 specs. The tubes are 6L6WGC from tube amp doctor,biased at 43ma, and the preamp tubes are the 7025 performance series from The Tube Store, performance matched. Initially thought the 2512 were OK, but nothing special. I had them in the twin in an open back. I kind of liked them, but something was missing. I have tried vintage EVM 12L, JBL K 120, eminence wizard, eminence swamp thang, eminence red white an blues and other similar speakers. In m opinion they were all ok but still something missing. I built a 2+ cubic foot wedge cabinet with a sealed back out of birch plywood. The cabinet is internally braced.Now these speakers really rock, very clean. I can turn the bass on the twin to 3 or 4 and have plenty, especially at low volume. I can crank the twin exceptionally loud and have it stay clean and dynamic. I can hear every pedel as it was ment to sound. All my vintage guitars sound clearly different from Gibson SG, Les Paul, Gretsch and Strat.Also I recommend matching other guitar speakers as I described above for different response characteristics . So far 1 eminence red white and blues and 1 eminence 2512 is one of the best combinations I have tried with a sealed back enclosure with my modded Fender Twin. I highly recommend this combo.

Rated 4 out of 5 by from Great speaker when used correctlyI used 2 of these in a pair of Bill Fitzmaurice Jack 12's and couldn't be happier. The application was for a High School drama club, so they needed to be rugged, easy to carry around and capable of enough punch to fill a 300 seat auditorium. The neo magnet makes for a very light speaker cab; both cabs are easily hauled around on a dolly or, with the installed spring handles, a very doable 1 person per cab carry. As a bass cab, there was plenty of clarity, but I'd suggest deploying these in pairs for that application; 1 12" lacked the oomph that bassists would require.These speakers pack enough punch to get low on full range music, yet are nimble enough to bang out midrange with authority. Designers should be careful of a rising response from 1k to 3.5k with a pronounced peak at 2.5k. In the right application, this can be used to your advantage (mains or monitors). In Bill's Jack 12 design, these speakers truly shine.Speaking of the right application, I'm very surprised at the reviews with 3 or less stars. Well, not so surprised considering they used this as a guitar speaker and nowhere in the product description or literature does it state that this is the correct application. Stick to Eminence's recommendations (Main, Monitor or bass guitar) and you'll be rewarded with great sound. Not every 12" is a good guitar speaker nor is every 15" a good bass guitar speaker.My biggest pet peeve with Neo speakers in general is that the price of Neodymium, a rare earth metal used in the magnet, has skyrocketed due to 4/1/11 tax increases by the Chinese Government, the largest exporter of rare earth metals. Due to this almost doubling in cost, I will be looking for other alternatives.

Rated 5 out of 5 by from Great value - light, handles a lot of powerI'm a bass player - (both electric and upright string bass. This is an excellent speaker. This is a replacement for an EVM 12L speaker and another Electro Voice bass speaker in a Mesa Boogie cabinet. The Eminence is smoother and more "musical" sounding speaker, and it is about 15 lbs. lighter!

Rated 3 out of 5 by from Great for certain applicationsWe make custom speaker systems for pro-musicians. Typically, clients need flat response and wide dispersion. There are applications and clients with different needs.For an electric guitarist who likes to be LOUD, especially in the 2kHz range, this is a good choice. Certain guitarists want incredible volume, yet don't want wide dispersion because they: 1- don't want to point their weapons at anyone else on stage, 2- don't want to fight with sound-men or band-members, so 3- need to aim speakers AWAY from open microphones onstage.Solution: give them one or two of these speakers in sealed cabs that angle up toward them from the front of the stage. Other musicians will not be directly in the line of fire, yet they will hear PLENTY of guitar without usurping precious monitor bandwidth.These speakers seem VERY HARSH to me. Yet off-axis, in the right cab, they sound pretty good. If you face your guitar-speakers toward the audience from the stage, these will offend everyone except hearing-impaired sonic-masochists. But, if you want small, LOUD cabs that cut through massive stage-volume, and you face your speakers toward YOU, instead of toward the sound-man or audience, these are useful. These can rip heads off at five feet. On the typical theater stage with high-ceilings and heavy curtains, these actually sound good off-axis at a safe distance. Those are exactly the characteristics that make this speaker popular with certain guitarists for LOUD ROCK bands on theater tours.Frankly, these sound better from the rear of the speaker than they do from the front, but that also makes them good for open-back cabs with low-wattage tube amps.The worst possible use for these is in a 2x12 combo amp where they will slice a vertical path directly in front of the amp toward any unlucky victim in their path. If that victim is the FOH sound-man within twenty yards, you will never be heard in the mix, simply because he will hear you above anything else.

Rated 5 out of 5 by from Great bang for the buck!I run two of these in a line array cabinet with a horn. Great clarity, easy to tune out the hot spots. Can be a little difficult to tune a cabinet to them, but not too bad. Very please with them (I have 8 drivers per side).

Eminence Deltalite II 2512 Neo 12" Speaker Driver

This speaker rated at 250w rms 500w power, but some list it as 500w max. I have been advised that the actual max is 1000w @8ohm. These will be used to replace woofers in jbl cabinets useing QSC QX7 amp at 2x 725 watts

Asked by: kingmike
Eminence does not rate their drivers as RMS, Program and Peak like some other manufacturers although these will still be fine with that amplifier.
