Combined cabinet power handling.

  1. Hi guys, i've searched around here and really can't find an answer for this very simple question.

    You have 2 8-ohm cabs (4x10), rated by the manufacturer as 700 Watts RMS each at 8 ohms. Now, you run them together in bridged mono mode at 4 ohms. Is your power handling now exactly/theoretically 1400 watts RMS?

    Simple question and i'm pretty sure the answer is 'yes' but the only reason I ask is, from what i've seen, a given manufacturer's 4x10 cabinet is always rated higher than half of their equivalent 8x10 cabinet, so i'm curious. For instance, my SWR Goliath IIIs (4x10) are rated 700, while their Megoliath (8x10) cabinet is only rated 1200 watts. Ampeg 4x10s are rated 1000 watts each while their 8x10 is rated 1600 watts. Any thoughts?

    Yes, you would have a 1400 watt power handling capability. It is different from the Megoliath because they most likely have slightly different speakers in there. Also, the Megoliath has part of the back chopped off, reducing the volume of the upper cab. Also, look at the SPL and frequency response for the Megoliath and Goliath III. The Goliath is 5 dB louder. I think they use different speakers.

    Just remember that numbers are a good starting point, but real world situations are far from "lab spec data"!
