    Hi everyone -

    Hope some one can give me some direction and a little education on this subject. I'm looking to match up a speaker cab or cabs for a SVT -4pro ampeg head, the head has 1200w@4ohms (2x600W). Does anyone have any experince with this head?

    Also a little bit confused on the listed ratings on the speaker cabs, 400 W RMS - 800 W program.:meh:

    Thanks in advanced DJ

    RMS stands for root means square. Rather than giving you the electrical engineering explination, its basically a rating of how much sustained power the cabinet can handle without causing any damage to the drivers. You can play through your amplifier and be putting out a constant 400W and the speakers won't blow. The 800W program means you can handle spikes or or peaks in power up to 800W. You just don't want to be putting a steady 800W through the cabinet.

    My experience is that an SVT-4 PRO sounds great through Mesa Boogie cabinets...
