Again i think the measurements well be dependant on what you are listening to and the concern would be with peak responce not continuous. Looking at the VTL site their power amp recommendations are based on woofer size suggesting that bass is indeed the controlling factor. Ex. their MB185 monos (230 wt/side tetrode) are suggested for up to 10 in woofers with mb 450s suggested for 12 in. There may be some marketing in there but the trend seems to be consistant. Another thing to consider beyond having sufficient power to maintain headroom is the increased. Another thing to consider is the increased dampning factor the larger amp has which helps control the speaker as it returns to neutral (i.e comes back after it generates the wave pulse) which tends to tighten up the bass. Again i think you are right on about the two amps being too similar to tell. Maybe the easiest solution to the dilema would be trying it both ways and seeing what sounds best
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!
