Help with speaker ID

So I got a old Peavey 215 cab with 2 different speakers in it
Here is the first one



And here is the other along with the spec sheet
http://www.pas-toc.com/pdf/drivers/ER-1580C-DATA.pdf




So does anyone know what the first one is?
Luckily the cab is separated into 2 sections so the speakers don't share the same airspace.
Is it cool to run two different drivers in the same cab in this instance?

Thanks for your help!

 

Thanks for the reply.
I didn't see any other part numbers on the magnet, is there anywhere else to look? Also, what are some good ways to test for polarity and any other parameters that I need to know?

 

I found some other numbers on the cone, 79629 but further googling leads me to believe that both of the speakers are PAS speakers. Apparently they make a ev lookalike like you had mentioned, the er 1580c that I had linked to previously.

I figured these PAS drivers are not good for bass guitar after looking at the charts and running them thought some modeling programs.
I found a great deal on an eminence cb15 so I'm going to run that solo, since the cab has separate chambers for each driver, until I save up for the other cb15.

I did the rice dancing test and the cab is tuned to 60 Hz so the cb15 should do ok in there. I might tweak it to +- 55 Hz but I'm not sure if there will be any real benefits from the tweak. The volume of the cab is around 2.7 (accounting for the volume of the bracing ,port and driver).

Any thoughts or comments from anyone on this setup?

 

The PAS didn't sound that great, lacking in the lows. Once I dropped the CB15 in the cb was waaaay better, cleaner and fatter. For $70 the cb is staying in ⚡️
