Is true-biamping now cheaper and easer?

Crown now, in their XLS series, sells high powered stereo amps (300 -500 per channel/8 ohms, doubling into 4) that offer a highly variable low and high pass filtration that can be channeled selectively into the left and right outputs. Moreover, the gain of each output is individually variable. Hence, two-way, bi-amping is now easy (you select the cross-over point, and adjust the volumes of the tweet and woofer) and cheap, ~$300-500 per speaker. Just get rid of that awful passive crossover.

Is this a great possibility, or am I missing something.

P.S.In responding to this, please realized that I don't believe that one can hear either cables or amps (given they have the watts). I prefer objectivity, something one hear it 'blinded'!

I would buy a real power amp first. Why bi-amp something like these? They give a power rating at 1khz only. That way, it sounds like a lot of watts. Who listens to just 1khz? True amps give the rating at 20-20,000 cycles. What happens to these amps when you run the full 20-20,000 through them? Half of the power rating? Worse? If you get a real amp, you might not have any reason to bi-amp it.

Like it was mentioned by other posters above.

These amps are cheap, and made for band with tight budgets to get by, otherwise they may not be able to perform.

Kr4 said it is very complicated. It definitely is. The audio reviewers probably would like to get more for their money, than they put in their systems.

Do you have access to the expensive test gear like they do to see the results from doing this? Beside sounding bad, it's easy to damage the drivers also.

Yes it may be cheaper to do this, but with digital noise added if you go the digital route.

Active adds a lot more parts than passive does. That means more money spent for more parts, and more noise.

In the end, it's hard to out do the builders that have the expensive test equipment, and are able to do a lot of trial error to get where they are. That's why I gave up trying to get more for the dollar years back. A lot of us has been there.
