Need Help Identifing ohms in Mesa 215 cab

[ghanlon]

Hi, I have an older Mesa Boogie 215 cab I am trying to identify Ohms for.

It is a monster, has casters and a solid wood front that attaches with 4 latches. Looks like 2 15" EVs inside and 1 - 1/4" jack in the back.

Pictures can be seen on my CL add.

Being that it's an older Mesa Cab, and could have had speakers replaced or the cab could have been rewired, your best bet is to get an Ohm meter and check it. If the speakers have the impedance on them, you can figure out the impedance of the cab by seeing if the cab is wired series, parallel, or series parallel.

They came in both 4 and 8 ohm versions (8 is standard). The best way to know for sure is plug in a cable and take a reading with a meter. GLWS. Thanks!

Thanks, so it looks like I need to take it somewhere that has a meter.

and to get at the speakers themselves to look I need to take the front grill off I am thinking. I have someone who may be interested in it but said only if it is 4 ohms.

Also I was under the impression that this was called a Mesa Boogie Diesel Road ready cab.

Is that correct?

Thanks for the great info.
I did a closer inspection today and removed grill and speakers to check for extra details.
Here is what I found
Both speakers look to be the same and stamped with

ELECTRO-VOICE INC
EVM MODEL 15L OEM TYPE
ONE YEAR (LIMITED) WARRANTY
MANUFACTURED_______________

815 9462 8910

The cone has a stamp on it
79842

The bottom speaker has an EV stamped on front looks like someone colored it in with pen, the top one does not, but is stamped on the back.

When you measure the static resistance of the cabinet with an ohm meter, it will read slightly less than the nominal impedance. So around 6.5 or so is an 8 ohm nominal impedance, and around 3.5 or is a 4 ohm nominal impedance.
