212 Open Back Cabinet (Silver On Black Badge)

nocodepensacola

I have an open back 212 cab with the later period logo (silver bell bottomed dudes) and square magnet Music Man alnicos. Does anyone know what this model is called? I play an HD-130 Reverb head with the 12ax7 phase inverter. This cab works great with my head, I just want to know more about it.

Hi Kenny,

you have the model 212X cabinet. The X stands for 'extension' cabinet. They appeared in either 1981 or 1982 (they are not in the 1980 price list). It's basically the bottom part of a 212 combo and could be ordered with MM speakers (like yours) or with Electro Voice as model 212X-EVM. Great cabs - I have the 210X and love it.
All I can say is - if you can get your hands on a 212RH cabinet to add to your stack, you'll have a sounds like nothing else.

Cheers,

Where can I get more information about the 210X cabs? I'm using 210s with my RD50 head, and believe it to be THE ultimate combination - no idea there ever was a production line of open back cabs...

Hi Ken,

I suppose these cabinets are relatively obscure. The RH and GS series cabs were early MM 'silver badge' products, the X series cabs were only produced for 3 years or so. What else do you want to know? According to the price list for 1982 there was also an EVM version of the cab. Mine has the two 'hockey puck' C10G Eminence speakers.
Do you want the measurements?

Cheers,

Lars,

Thanks for the information! I got this cab because I originally wanted an HD 130 combo but ended up with the HD 130 Reverb head. I played through a 412 GS cabinet for the first six months or so of owning the head, but it was too big and loud to bring to the shows I play. I got the 212X cab on ebay, hooked it up by itself, and it sounds as I would imagine the combo would. Now that I know it's intended to be an extension cab, should I be running it at 4 ohms? I've been playing it at 8 for the last few months and it seems fine. Thanks again,

-Kenny

Music Man's standard speaker drivers were standardized at 8-ohms impedance.  This way, they only had to stock a minimum of speaker models.  The single speaker cabs and combos run at 8-ohms.  Two speaker cabs and combos are 4-ohms (wired in parallel).  Four speaker cabs and combos are 8-ohms (wired in series/parallel). 

If the 212 cab you are running is the ONLY cab and it contains the factory loudspeakers then you should run the head in the 4-ohm position.  You can verify this by measuring across the speaker cable plugged into the cabinet with an ohm meter.  You should read about 3.2 to 3.6 ohms of resistance.  An 8-ohm cabinet would read about 5.5 to 6.2 ohms of resistance (approximately).
