Old EVB 15" bass speakers....

[agedhorse]

I don't know if these are the same as the original drivers.

Only the used ones, all the clones and the one new aftermarket drivers are counterfeit or knock-off.

Nothing sounds like those old EV 15s. The single best live bass sound I ever got was my old club rig, which was an early handmade PRS fiver into an EVB and and EVL in Bag End boxes powered by a Walter Woods.

Imagine a slightly fuzzed pre-CBS Jazz Bass driven homicidal by PCP and Jaegermeister. Such an amazing sound.

Still have the prs?

Sold it about ten years ago after I went 100 percent upright, and while I was married to a spending problem.

Ironically I was just looking at my old Fender 215 cab loaded w/ an EVM 15B and 15L, sitting in my garage. I was thinking I really ought to get rid of it. Thanks to you folks, it’s staying

who out there has had a great experience with the EV15B's ...

Are the "EV15B's" of which you speak the same as the Electro-Voice EVM15B and/or EVM15L that were available in the early-to-mid 1980s, or are you talking about a model that proceded those EVMs?

AFAIK Eminence Delta 15A or 15B are voiced as close to the EVM as any driver. No idea how close their T/S specs are.

Thank you for the charts, this is the kind of thing I was hoping to obtain from the 'community'. I'll use this as a 'base'.

FYI, what you have is the original 200s cab, manufactured approximately from 1966(or ‘67?)to 1970, paired with their flagship 200s head(ultra linear design, 60 watts from a pair of KT88’s or 6550’s. The cab’s unique internal design was not derived scientifically, but, as legend has it, it came to Conrad Sundholm in a dream. He utilized JBL D-140’s(130’s for guitar cabs), as the baskets were shallow enough to fit in the tight chambers created by the port throat. They would be installed through the back(hense the back panel with all the screws). The success of the cab was due in part to the use of that particular driver, in that serendipitous manner.

This all makes me wonder, how are you fitting deeper EV’s in there? I would assume through the front, but keep in mind the cab wouldn’t necessarily be optimum for those drivers, not quite enough volume. The later 215B cab, same outward size, which emerged around 1970 and was more often paired with the solid state Concert head, had an entirely different internal design, somewhat similar(but not exactly)to Mesa Diesel cabs that employed EV’s, front loaded/sealed back, with a verticle side port. These cabs had a proprietary driver(not JBL), manufactured by CTS or Eminence(I forgot which).

There was also the earlier Sorado cab, same size budget version, with just a straight one piece baffle board and two small round port holes and cheap CTS speakers. I’ve own all three, still have a complete 200s rig and a 215B that I placed a pair of mystery Cerwin Vegas in, to good results, powered by a Fender Studio Bass amp in head form.

I had mounted the speakers from the back.....

15B's from the 80's

Thank you for your post, I did see these and I seem to remember mine looking like the first photo on the left...roundish recessed frame. My quest is for new products that may share relative 'response' to these perhaps 'questionable' 'vintage' items in a feeble attempt to align my sourcing with 'modern' factory support and communications....lol. I may end up exploring the 'used' market, however.

Sheesh, how did you manage to fit them in? Did you remove the magnet covering, so that they looked like this…

Then, the internals of your cab look like this(on the right)?

Those are the proper JBL D-140’s, much shallower, and even then a tight fit with that angled board as you slide them into place.
I tried placing EV’s in a 200s cab once, damn near impossible without a struggle, but if you managed to without any modifications to the board, kudos to you.

Just keep in mind that, even though it was not arrived at according to specs, the pairing with the JBL’s worked out fine. I would think you’d need a bigger box with the EV’s, as per the classic TL design.

I will call your attention to this comment:

The EVM 15B is not very similar to the Delta 15 drivers, the L's are closer but still different.

Closer is the Delta Pro.

Delta Pro 15A

Check my profile pic, all EVM, until 2 months ago.
Replaced with Eminence Kappalite 3015, all I had to do was shorten the port by half. But they will still work fine in a TL606 cabinet. 3.2 cu.ft, 24 sq.in port 4” length.
Gained an octave in low end, lost nothing in tone, lost 10 lbs per cabinet.

Do it!

 

[edervjo]

The EVM’s did not have the excusion the newer drivers have, only 3.3mm v 6.7 for the Eminence. DO NOT GET THE LF’s, they sound mushy, and are not efficient, power suckers. But the std Kappa has that upper mid bite like an EV, and are very responsive to eq’ing.

If I remember correctly both of my Fender Studio Bass combos came with EVM 15B's.

Got a pair in ‘84, served me well until now, Good friends.

Yep, near as I remember. The open cab back pic on the right is the one..... I don't know what the bigger cab is on the left but the screw patterns are the same. This is what my current plans look like although they were skimmed from Dean Markley. I appreciate your interest...

The one on the left is the upgrade model, the 2000s, introduced in 1968, as used by Noel Redding with Jimi Hendrix. The size was expanded in order to accommodate added power tubes to up the wattage to 120 over 60 from the 200s, and possibly to match the cosmetics of Marshalls, which were being seen more often in the US at the time. The insides of the cab were essentially the same, just wider and taller, and dual JBL D-140’s were still employed.
Here’s mine…

...So I'm poking around looking at JBL D-140's...would you happen to know the difference in designations for these? i.e. JBL D-140 'F'...or whatever?

 

[agedhorse]

The F has a slightly wider gap to improve reliability for MI applications.

The D series is good for between 50 and 75 watts for bass guitar. Be aware of this.

If I remember correctly both of my Fender Studio Bass combos came with EVM 15B's.

These weren’t stock. I destroyed the OEM speakers in short order (it was the 70’s…) and the local music store, Zapf’s, sold me the EVMs. Both were reconed at least once. As I recall, one of the recone jobs involved a trip to a sketchy shop in West Philly.
