Would your sound not be the same? I can kind of understand bi-amping helping in a situation where you have a active Xover prior to your amp helping but don't understand it in a passive set-up. |
by not having to drive low freqeuncies with the HF amp you will get lower distortion.
But to really benefit you should run an electronic cross over before the amps. a Pioneer cd 625 or 635 is not that expensive. There are others available also for under $100.
There are many benefits to proper by amping with electronic crossovers:
The amps only have to amplify High or low signal (or mid if you triamp), your tweeters never see distortion cause by the huge LF signal.
You eliminate the passive components in the crossover and that results in better damping factor and the amp sees a better load, not the big inductor and cap of the crossover (simple explanation to a more complex subject
With Electronic xovers you also get much finer controll over frequency and level
hope it helps
but keep in mind bi or triamping is really for higher end sytsems, really good speakers, proper placement etc.
you actually 2x the aparent power, in other words, you would need 200 watt amp covering the full range in order to get the same dynamic range as 2x 50 watts biamped with Exovers.
