I wouldn't worry about it if I were you emedwhat. The reason is that you are basically doing an active bi-amp since you are using bookshelf speakers and using a subwoofer to do the bass notes. The only difference is that the woofer is not in each one of the speaker cabinets, but rather, it is in its own enclosure which is optimal for the driver's Thielle-Small Parameters. It'd be a bit pointless to bi-amp bookshelf speakers because you would only be separating mid frequencies from high frequencies. Neither of them require that much power in the first place, assuming of course that you have the crossover and subwoofer enabled in your receiver.

In reply to:
Now, you find that your passive bi-amped set up does sound better? Cleaner at high SPL? Better in general? I understand that this would put a lower load on each amp, therefore getting essentially more SPL with less strain on the amps and thus reducing the chance of clipping. But say at 88-100 DB does it actually sound better? I am just wondering.
I would be lying if I said that I could actually tell the difference when I passively bi-amp given the same loudness level. If the amplifiers are equivalent, passive bi-amping should never sound better at any given non-clipping volume. This is just like how bi-wiring should never sound better.
This may make you ask why I do that at all... Well, I have a 7.1 channel receiver (the Pioneer VSX-1014 Tx). This receiver gives you the option to use 7.1, 6.1, or 5.1. If you select 5.1, the receiver allows you to either use the extra two amplification channels to bi-amp your main speakers or set up a multi-room system. Since I no longer have high quality speakers in other rooms, I chose to bi-amp my main speakers. I like having those extra 3 dB of dynamic range if I ever need them.

Thanks Will.
That's nifty. Mo' power. Power good. I like that.

I read this article then I needed to understand the issue.
http://www.ultimateavmag.com/avreceivers/605arcam/index1.html
//////////////////////////////////////////////////////////////////////////////////////////
On the Arcam, however, a menu option allows the two extra amp channels to serve your main L/R speakers in bi-amp mode. In my system, the result was a dramatic improvement in overall sound quality with both stereo and multichannel sources. (Speakers with bi-amp capability have separate pairs of input terminals for the high and low frequencies, which are normally jumpered together. In a bi-amp situation, the jumper is removed and each speaker is fed a full-range signal from two separate amp channels via two separate speaker wires, one connected to the speaker's HF terminals and the other to its LF terminals. Most high-quality full range speakers are bi-amp compatible.) "The text was taken from the article writen by Lawrence E. Ullman, June, 2005 at UltimateAV.com"

IMO bi-amping became largely obsolete the day that powered subwoofers became the norm in home theater systems. When you are running a home theater system and sending everything below 80 Hz to a subwoofer, you already HAVE active bi-amping in every sense of the term... electronic crossover, separate power amps, yadda yadda.
If you are running full range music speakers without a sub, where the same speaker is handling the deepest bass and all the other frequencies, and you are running at extremely high power levels, then bi-amping is still valid and beneficial.
I think the author was talking about larger speakers like Axiom M60 or M80, which are all configured in exactly the way the author described. Honestly, I don't know ANYONE who would want to bi-amp a bookshelf speaker like the M22.

Em, there's no good reason to be sorry that the M22s don't provide for passive bi-amping(or biwiring)since it has no significant benefits. Each channel of the amp still carries a full-range signal and each section of the speaker still has only the power of one amp channel available. For example, if two 100 watt channels were involved in a passive bi-amping arrangement, each speaker section would still have just the original 100 watts available, not 200 watts. As Will pointed out, you're already receiving the advantages of a form of active bi-amping when you use the bass management of your receiver to send separate frequency ranges to the sub amplifier and the speaker amp channels of the receiver. As far as the review in Ultimate AV, I can't find that comment to be any more credible that any other audio illusions we often read about.
