OK, this is my first impression on the tone of that M212 based on a few hours comparison between my Glockenklang 4x10 8ohms and this 2x12 in 4 ohms.
The amp is a Glock Soul.
First volumewize, if you set the same volume on the amp and switch from one cab to the other, the general volume seems to be the same at home although one cab is 8 ohms so receives 270W and the other is 4 ohms so receive 440W.
I think it can be explain in term of speaker area.

No in term of tone, this M212 is all about clarity, articulation, brightness and in a way agressivity. My feeling was as if I were playing through a big monitor or a highend hifi speaker.
Problem is that for me a monitor is not a bass speaker and I realy feel that with everything flat on the amp, the M212 realy lack some thickness in the tone. Everything sounds quite thin and it is quite evident when you solo the bridge pickups of a JB you get that very thin sound that you need to work to get a bit more meat or substance.
The speakers are realy quick and the note pop out with energy an punch, especialy in percussive technic where you realy cant miss the single ghost note. That, combined with the mid oriented tone, gives quite an agressive general feeling which work well with my playing.
With the Glock 4x10», everything is about smoothness and thick solid tone while staying absolutly articulate and clear. The JB with bridge soloed doesnt need any eq to sound instantly good.
This Glock cab is realy something to be heard.

On the highs department, I still have to work with the tweeter switching system to speak about it but it realy seems genius. In higher level of the soft attack setting, the highs of the two cabs seem quite similar with maybe a bit more sparkle for the Glock, something that Ive always felt was part of the Glock tone.
Well, if youve read my review with attention, now you must think , this cab will not be a keeper .

The very good news is that a slight touch of the eq is enough to make it sound realy close to my beloved Glock 4x10 ».
With the low mids (130hz) at 1PM and the mids (880hz) at 11AM, things instantly get thicker and quite familiar to me.
The M212 can take quite a good amount of eq in the low department but this will have to be verified at gig volume.
So yes, this cab is a keeper for me. It is not exactly what I was expecting in term of tone but thing can be work on the eq to make it closer to what I like.
My ears could also be used to that Glock tone Im familiar with for 6 years now.

Anyway, if the S212 has less low than the M212, Im glad I havent found one since I already feel the M212 lacks a bit of substance when the amp eq is flat.

Now waiting for the test in real gig situation.
Regards

I'm sure Glenn Kawamoto and TecAmp will take care of me, but it's never really easy when the parent company is across the ocean and the brand is small volume in the US.
