Re overloading a single MB head
I thought I heard ( here at TB ) that one could use TWO amps simultaneously. I have no idea how, and if one of you could comment on that
If 2 amps ( MB) are feasible, How? And how would one control the way they blend?
Thanks
You would run a line from the effects out of the first one into the effects in of the second. The EQ of the first one will control.
You would plug your bass into the first amp. The EQ from the first amp should control both heads. The volume would be controlled separately by each head so you could have more volume into the larger cab and less into the smaller one.
Thanks, I'll give it a whirl. But, I realize that I will still be playing 300w, only through two speakers instead of one. But, at least it's a way to gain a few dbs, I guess, maybe a fuller sound?
Give it a try to see if it works for you but I think you'd really only need to do this if you wanted to run four 8 ohm cabs.
1. I have a feeling The MB CMD 102P has a unique sound - combining my LM2 with a MB 210 may come close. But close, is not where my ears live.
2. What is it about MARK BASS cabs and amps esp LM F1 and many of their cabs that just seem to have a unique sound to them? More specifically the MB mojo seems borrowed from Ampeg but with Some x factor I can't seem to describe.
Unless someone urges me otherwise I am getting the 102 combo
Russell. "get me on it"!

Based on the quote above, I thought I should do some checking to assure the safety of my amp and then report the results of my research.
I wrote to MarkBass last week asking them the question about my setup.
Recall the setup was a CMD 102 P with an extension cab, STD 102 HF (8 Ohm), plugged into the amp and a Traveler 102 P (8 Ohm), daisy chained from the STD102 HF.
MarkBass has not responded, but I had a discussion about this setup with a colleague who is a well respected, top notch electronics technician who also designs and builds custom amplification set ups.
My friend tells me the two 8 Ohm cabs coming from the amp increase the load on the amp by reducing the Ohm rating to 4. He says further that when the third cab is added....not direct into the amp, but daisy chained from the extension cab....it has a multiplying effect on the Ohm rating and thereby does not further increase the load on the amp. His analogy was, "The third speaker connection is like daisy chaining PA monitors together, it doesn't increase the load on the amp".
I'm not certain about the math to get to the Ohm rating for my full setup, but according to this tech, the rating does not fall below the maximum 4 Ohm load in the setup I use as described. He has assured me my amp is not in danger of overloading.
If someone knows something different, or knows the calculation to get the the load rating, I'd appreciate hearing from you.
If I get a response from MarkBass, I'll post their reply here.
Koog.
As far as OHM calculations, two 8 ohm cabs brings the ohms on the amp down to 4 ohms. (Minimum ohms for Markbass heads) I'm not sure what 3 8 ohm cabs brings the ohms dow too but it's below 4 ohms. (Of course if your friend is right about daisy chaining you're safe) and 2 4 ohm cabs bring the ohms down to 2 ohms and MOST bass heads won't run down to 2 ohms. The only heads i know that run down to 2 ohms are Carvin bass heads. (At least the new ones do) So generally, for most bass heads you can use one 8 ohm cabinet, two 8 ohm cabinets or one 4 ohm cabinet. (Or four 16 ohm cabinets if you can find a 16 ohm bass cabinet!) ;-)
