I'm hoping to build myself a nice 2.1 system based around a DCX2496 for nearfield use, and was wondering what the thoughts here are on the use of two satellites with a single subwoofer. I'm aware that this configuration isn't idea, but it is very cost-effective, and lets me use some very small cabinets. What are your thoughts on the subject? What is the minimum crossover point you would use for such a setup?
Multiple satellites with a single bass unit is still a very common set up and works well if implemented well. Implementation is all about speaker placement. You will have to experiment with your environment to get it right for your tastes. About the highest you want to run the woofer is 100 Hz + or -
The crossover point depends on the lower response of your satellite speakers to get the best out of your system. Theoretically the -3dB point is required and the crossover would be set at this frequency. As with all Hi Fi theory and practice don't always agree and some setting up is generally required but you should have a good starting point.

I'd take it to 80Hz, then. Because then your subwoofer will be a few dBs down at 100Hz (the general frequency quoted for when it becomes locatable).
I've used a 2.1 setup for some time, it definitely works (and works well!), though stereo subs could be worth considering, as I've found room peaks and nulls by walking around.

I agree with Chris, at 80Hz you'll be in the more linear portion of the speakers. As for peaks and nulls I wouldn't worry, you get that in any room, I've found that the brain immediately compensates for room acoustics. Always let your ears be the final judge.
