I did a search but didn't really find anything useful so here goes... It's my understanding that when you daisy chain two cabs of equal power handling, the wattage doesn't just double, it's less than twice the wattage of either of the single cabs? Does anyone have a formula for what the powe handling of the dais chained pair ends up being? for instance i'm planning on buying a Tri 112 which is 350watts and an 8ohm cab. i'm powering it with a bridged RMX850. if i daisy chain two of the cabs(later on), it will be a 4ohm load and i'll be able to get the full 830watts out of my poweramp, but how will my headroom be?
