From the seller
Mint minus or Mint- condition on these closet-kept rare birds!.
.
The spec sheet says it best: "what's the result of all of this?? The EV SRO 15L will turn you on!" Lol.
.
These were the rare SRO 15L instrument speakers, with a hefty 100w a piece, and these are two of the cleanest original circa 1971 originals I've ever seen!.
.
Take a good look at them! Many of these were blown up by uneducated clods in the 70s, thinking that all EV SPEAKERS could handle 400 watts..
.
These do 100w, of bass OR guitar, PER SPEAKER, as they're voiced with a mid forward, full frequency kit in them. Also great as full frequency monitors, with a super tweet. Being full frequency instrument speakers, they aren't woofers, and should be treated as such. Don't put them in sub bins! The aluminum dust caps are original, and afaik may have only been on the 15L in the early 70s. At some point they were changed to a felt paper EV logo cap.
.
.
These originals are beyond scarce! Most were gigged on until they sat as used frames, reconed, and possibly on their 4th or 5th kit by now. That's why these time capsule pieces are so precious, and i rarely buy raw speakers... but when I do, it's only ones that i would buy for myself. I'm already feeling the twinge, that these would sound so great with my Traynor 1973 Reverb Master, in its original 2x15 cab... one month!! Lol
.
.
I'm including the original spec sheet, and cabinet plans in the photo section. Feel free to copy them, and use them for your own!

Check a lot of the other ones out on the market and you will see a lot of recones on these. The originals are as you see here with a brownish anodized aluminum dust cap, and the tinsel leads visible from the front on the sides. They also are characterized with smooth felt paper cones, which also help the full frequency "bloom".
.
.
They are awesome speakers for articulate amplification of ANY electronic instrument, including electric pianos, or any tone-heavy "real" instruments that use coiled pickups
.
.
They comfortably occupy the frequencies you need for these and set perfectly flat in the mix for these instruments, with a pleasant taper above 4k, that allows SOME highs, with the highest frequencies dipping down by the time they reach 10k.
.
.
The dust caps sit directly on top of the voice coil, and are glued securely to extend the high end frequency response, but not to the point of causing too much high-end hair on an overdriven signal. They have a sweet curve that descends gently as it goes above 4K. 10K is about the limit on these, and would generally give you about 12 DBS less than flat response at that point.
.
.
If you give them the prescribed 100 Watts a piece, they'll be more than loud enough as they're super efficient, and last you till your retirement!
.
.
These show positively zero gig wear. Original through and through. The gssket and frames show that they maybe came stock in a double 15 cab, with only the faint outline of four mounting screws showing on the white painted frames. The front gaskets and cones are pristine.
.
.
These were kept in original shipping cartons, as you can see the traces of Styrofoam on one gasket. They have not been cleaned. Jusy tested with some full frequency program material, up to 100 watts.
.
.
These also have been utilized in high-end, high output studio monitors. I don't have to tell you that Electro-Voice speakers are special, but these are probably some of the best instrument speakers ever made. They are as clean as you will ever see, and if they don't sell in the first month I'm pulling them off and using them myself. Fair warning!

Listed in the last week of October 2026. As these are from 1971. I can send you a video of them fired up. But when they leave here they are yours. So consider that sold as is, with proof of functioning before they leave. Enjoy them and thanks for looking!
