If you have mono amps, I would put each mono amp under each speaker, it also saves space and it allows you to keep your speakers cables very short.

A speaker stand with room for an amp?
I have rather large 2-way stand/bookshelf speakers and I'm thinking of going 100% active with them. They have an external passive crossover already, so there's nothing to rewire internally. What would be nice is if there were room for a small Class D stereo amplifier to be hidden in the stand. Even better if it was adjustable for angle.
