In sound reinforcement set ups we always use significantly more power on the bottom end than on the tops (like around 1200 wts/side or better on the subs vrs less than half of that on the tops). The bass is what drives most of the peak power requirements contrary to Eldartford's generalization. (though that could be dependant on what you are listening to...chamber music probably doesn't hit the bottom end too hard where as anything with thump most certainly will). keeping sufficient headroom keeps the sound clean and prevents clipping...clipping can be expensive. It sounds to me that you are doing the home theater thing....big amps to the bottom end no question.
Biamping; Amps w. Different power ratings?
If a person uses two amps of differing power levels, will there be a noticeable difference in volume? I've got an Outlaw Audio 755 which is 200wpc. I'm thinking of adding an Outlaw 750, which is 165wpc also. I would use the lower power amp for the bass, and the higher for the treble.
I will have a speaker system comprising four Eminent Technology LFT-8's (biwired and biamped configuration for each of them) and will use 8 channels of amplification. The four bass drivers would be from the lower power Outlaw amp (165) and the highs from the 200wpc amp.
Or, would I be better served to make one speaker completely driven by the 165wpc, and the other by the 200wpc?
I will be sending signal to all 8 amp inputs through the same preamp - a Rogue Audio Magnum 66 (which has a selectable second main out; the signal from each pair of outs will be split and delivered to the 8 amp inputs.
So, would the difference in power cause volume discrepancies between either the bass and treble, or between entire speakers (depending on how I hooked them up).
Comments, suggestions welcome!
