Another Bi-Amp Question

I have B&W 805's for front speakers and a Pioneer Elite A/V Receiver (VSX92THX). The speakers max power handling is 120W and the Receiver max output is 130 watts into all channels. Here is my question- I can biamp the fronts using the surround rear speaker outputs. Would I need to worry about frying my speakers? In otherwords, would the B&W handle max 120W into each driver? Or, would I be putting out (max ) 130w X 2 into each speaker?). Sounds awesome the way it is but if I can grab a bit more power w/o damaging anything, why not? (It is an HT system only).

Thanks,
cerrot

You can try it but why? Assuming(!) the quoted numbers are accurate, you have speakers with a max power handling of 120w connected to amp channels with 130w output. How could or why would you think that biamping would get you any more volume output (without distortion)?

Cerrot: The only possible reason for bi-amping (without replacing the built-in crossover with a custom external one) is to increase the power output to the speaker. However, any such increase is minimal. There is no reason to expect any other difference for the bother. (Gratuitous opinion.)

Hifitime: That is simply false. Impedance analysis will demonstrate that each leg of a crossover will still show the same impedance as the combination since each leg will have a very high impedance outside of the pass-band for that leg. The individual and combined pass-band impedances are the same. Thus, with biamping there is no loss of output and any power increase is real but minimal (<3dB).

I believe you guys are correct for the frequency range it will be driven at.I'm thinking of full range drivers.
And what is the relevance of biamping for full-range drivers? Why not simply use a better, more appropriate amp?
