Is EVH model 15L speaker okey replacement?

Perhaps you mean EV-M 15-L?

That's a very good speaker. Not a lot of super deep lows, but it'll get plenty loud with pretty good tone. High end is decent enough that you don't really have to run a tweeter with it; you can if you want really sparkling highs, but it's not absolutely necessary.

I've got an old Sunn 2x15 loaded with EV-M 15B's - it'll get as loud as any normal player could want. It sounds way more old school than modern/hi-fi, but it'll easily get the job done. 15B's are almost identical to 15L's. It is pretty heavy, though. I'd advise casters or a dolly to move something like that around.

 

I've got an old Acoustic 306 that's loaded with
EV's. I got the cab for nada and when I first heard it, I knew it needed something. I found the top speaker was ill, pulled it and found it was indeed a EV-15L. Real kicking speaker actually. Like was said earlier, not as deep sounding as a 15B, though. Here's the thing with me, the bottom speaker turned out to be a 15B, the (2) of them in together in the cab work a really intense tone. Once I had the EV-15L reconed, it rocked. I read somewhere that Geezer Butler uses/has been using EV-15L's as part of his stage rig since sometime back in the early-mid 90's. The article says he loves 'em.

 

The 15L extends higher than the 15B, up to 5khz. The 15L has a cone that has two ridges that run around the cone. The 15b cone is totally smooth and rolls off I think around 2khz, but extend lower than the 15L.

Combining two different speakers both in the same enclosure may be classified as a "no-no". the magnet, cone, and voice coil diameter should be the same in appearance for starters.

I know EV discontinued the EVM series and came out with higher rated drivers than the classic series two (200 watts) and pro line (400 watts)
but I don't know for sure if the new line is called EVH. I think the newer ones are rated a 800-1000 watts and have 4" voice coils. Really a different animal.

 

The Mesa "Black Shadow" 15s were rebadged EVM-15L speakers.

 

My collection includes a 15L, a 15B and a 400RB. I still think this is a great rig. The 15B replaced a 15L that I fried while trying an experiment with my 1001RB. Although I prefer the 15L to the 15B, I agree with hammer2748 that pairing an L with a B produces more booty.

 

I put an Mesa Black Shadow in a Yorkville 115BX cab and that thing pumps
