    I'm interested in GK's 212MB-II, and I'm confused on its specs. Most places say it's 500watts, but GK's site says it's only 350watts. Anyone know what it's really rated? Thanks.

    The MB212 II is full 500 watts. The 2 12" make a 4 ohm load. The same head with the 210 speakers is "only" loaded at 8 ohms and without an 8 ohm extension cab will output 350 watts.

    350w at 8 ohms, 500w at 4 ohms. That means as it sits, it's 350w, but if you add an 8 ohm extension cab, it's 500w.

    The note in the corner explains the asterisk and the 212MB-II does not have an asterisk next to it. Only the 210MB-II does.

    B-string explained it correctly.

    Wow, GK does a crap job of telling you the impedance. Asterisks and exceptions is no way to quote specs. Just say it in plain English what it is. Now I'm assuming that the 212 combo is 4 ohms and runs at 500w, but this is one of the most confusing ways to tell the specs of a series of combos that I've ever seen in my life.

    Looks like only the 210 is 8ohm and takes an extension cab. The little ones do the powered extension cab thing. Crazy thing is the 210 @ 350w spec is probably a crock unless they are using some special tens.

    This is my understanding. The other cabs are set up to use additional powered cabs only.

    I don't find it confusing at all. One asterisk on the left side and then an explanation on the right.

    It seems direct and to the point to me.

    It is a little confusing (to me) that only one of the combos supports an extension cab.

    Read the manual? The only thing it says in the manual (which covers the entire MB combo series) is:

    Output power: 350w @ 8 ohms, 500w @ 4 ohms.

    GK makes fine stuff, but I'm a 35 year working pro, and it's even confusing to me, as well as the OP.
    No mention of the different models and what impedance the combo cabs run at. Yes, that is VERY confusing. It should very clearly state that the 212 combo runs at 4 ohms as it sits.

    I'm pretty sure that all the MB combo's have the "chain out" to drive the MBP powered enclosures also.

    They do, but only the 210 can support an unpowered extension cab.

    I guess if you have no clue how to read footnotes it might be confusing? Maybe they should teach reading again in schools. :)
    Clearly states right next to the MB212 II, Power output 500 watts.

    They have a dedicated balanced +10db output from the preamp that interfaces with the self powered MBP cabs.

    I apologize, TB. I meant the 212MBP powered cab. Again sorry my confusion caused any here.
