Audiobb, my experience has been that while you can get much greater volume levels by bi-amplifying, you also pay a big price- figuratively and literally! First, to do it right you have to use and electronic crossover. Good ones are expensive, and all of them behave not only as crossovers but also as filters for detail and impact. You also have to pay for another amplifier.
I have found the most convincing systems don't use electronic crossovers, instead the amplifier drives the speaker full-range. Otherwise you face prodigious integration issues, and the better your speaker is the more you will notice them. For example, its a lot easier to bi-amplify if you use the same type of amplifier for top and bottom, as far as integration is concerned. That could be tricky in your case where you have an SET on top.
At any rate I've never seen a bi-amplified system work right. I've seen them sound OK, and I am open to the idea that one day I'll hear one that is done right but until then I advise against it- if best possible sound quality is your goal.
