FDP Forum / Miscellaneous and Non-Fender Topics / Electro voice evm12L: Replacements/Equivalents?

The EVM12L I have may have developed a problem after 35 years of use, even though it has almost always been played at bedroom levels.

There is a weird metallic sound at a particular note (Bb). If I bend slowly from an A to a B or vise versa it comes and goes right around Bb.

I'm pretty sure it's the speaker and not any tubes or cabinet rattles or the guitar.
It has a paper dust cap.
I checked it and the come for any tears and didn't see any.
It's a combo amp, and I need to try it outside of the cabinet to make sure it's not some weird cabinet rattle going on.

I'm surprised that this one may have gone bad, considering that it has basically never seen any high volumes.

Anyone ever had something like this happen, and if so what was the culprit?
Did you fix the speaker or just get a new one?

In the event that I need to replace it what is a reasonable equivalent in terms of power handling (the amp is 100 watts) and response?

Thanks in advance.

There really is no direct substitute for the EV. They are very durable speakers--so before you throw in the towel, make darn sure it's the speaker that's bad. I'll bet a paycheck it's something else like loose hardware in/on the combo cabinet, or perhaps a preamp tube gone microphonic.

I had an EV speaker in my Mesa Boogie 1x12 Thiele closed back cab. The label on the back said it was 200 watts. Could not believe the amount of headroom and low end that cab had. Ended up selling it but I have fond memories of how powerful that EV speaker was. Huge!

Eminence makes a replacement. 200 watts super efficient and weighs about 16 pounds. It’s close enough for me and half the price.

I have that Eminence in a modeling amp. I recommend it as well.

I have 4 or 5 EV12-L's and they are great speakers. Wish they weren't so darn heavy.

Update: After posting, in parallel I continued troubleshooting.
I just didn't see how it could be the speaker, knowing how it has been lightly used.

A couple of the screws holding the speaker were not as tight as they could have been.
They are now.

I took the electronics/chassis out of the cabinet. Still "buzzed", and on a couple of other notes as well, and worse.
So with the chassis removed it's not a microphonic/vibration issue. The only things left in the cabinet were the speaker and...... the reverb pan. I played a note and got the noise going, pushed down on the reverb pan and guess what?

After 30+ years or so, the screws holding the pan down have rubber washers/grommets/isolators on them. They got kind of hard or worn out. Went out to the garage, found some suitable items to use, and I'm back up and running.

Yes, I tightened up any other screws I could find while I was at it.

Just wanted to update the post with the solution, as a courtesy to all those that chimed in, since a lot of people don't always report back.

As for the weight...........
The amp is a 1984 or so Carvin XV112E. Heavy? Picking it up it's almost as if it was bolted to the floor. It's like they were trying to copy an old Ampeg VT-22 or something. It got casters put on many years ago.
