    I'm thinking about getting the Markbass LM800... but I want to run 2 cabs off of it. I have a 4ohm 412 cab, and want to run another 4 ohm cab... but there's only what appears to be ONE output?! Is that correct? I don't want to daisy chain cabs... I'm accustomed to seeing most amp heads with two outputs...*** markbass? Make an awesome head with a mono out... *sigh*

    Even with two outputs, you couldn't run two of these cabs, it isn't 2 ohm stable. Daisy chaining is the same as using two outputs, too.

    Two four ohm cabinets will be a load of two ohms to the amp and according to this page the minimum load for that amp is four ohms.

    In other words, you can't do it.

    What's wrong with daisy chaining cabinets ? As long as your speaker cables are adequate there should be no problem.

    Minimum impedance is 4 ohms, so you can't run another cab anyway.

    You can NOT run two 4 ohm cabs from MarkBass. Minimum load is 4 ohms and two 4 ohm cabs will be 2 ohms = fried amp. You could use a special made series cable to run two 4 ohm cabs in series with the result of a drop in output power at 8 ohms (in which case you only need one output on the amp anyway). Dual speaker outs on most amp heads are mono still anyway.

    You can do it. Have someone make you a cable so that the 2 cabs are in SERIES (+ to -). You'll only be running @ 8 ohms, but moving more air.


    Also---- there is nothing wrong with running one cabinet to another (parallel). A parallel connection at the amp or cab is still a parallel connection.

    True, however, the power loss will essentially negate any gains from the additional speaker area. There will be a gain, but most people will only notice it with a meter.

    Then listen. I think the two cabs will be louder with less headroom at the amp.

    I have. I own a sound production company, and have thus had the opportunity to try all kinds of setups.

    Either Genz Benz GBE head, Ampeg SVT-CL, Ampeg SVT-VR, Ampeg V4B. I'm sure there are many others, but these are some really solid options.

    That's a good head, and a screaming deal right now. The tone isn't to my taste, but a lot of people like them.

    what about the B2000? seems like a simpler control set, which I like...

    will it get a good metal tone?
