    you could run 4 8x10s with the SVT-4PRO!

    Not sure about the 8PRO though.

    It is not true. The SVT tube of the 70s will do 2. Maybe others do also, but this one for sure. I use it regularly. :cool:

    The 6PRO can only run one 810

    The 8PRO can run 2

    If you want to run two 810's I would get the 8 pro because you would be running about 1250 watts to each cabinet.

    With the 4 pro into 2 810s you'd only be putting out 300 watts RMS to each cabinet (900 peak)

    Pfui..........

    The 4PRO runs to 2 ohms per channel, 4 ohms mono.

    The 8PRO runs 2 ohms

    The SVT runs 2 or 4 ohms........

    Others run what they run ohms wise, look at the ratings

    The usual 810 is 4 ohms.......... so 2 daisy-chained is 2 ohms.........

    So for instance the 4PRO can run 4 4ohm 810 cabs stereo, or 1 very loud in mono

    The SVT amps can run 1 OR 2 4ohm 810s.

    No amp commonly use in music applications will run 4 4ohm 810s FROM ONE CHANNEL OUTPUT (neglecting the Grateful Dead and their big McIntosh system)

    in other words,

    since the cabs you mention are 4 ohms, and putting them together would make for a 2 ohm load, and as long as the amp can handle a 2 ohm impedance, you're golden.
