Even large mains that can supposedly handle the full 20hz to 20khz frequency, in my opinion, should still be set to small.

It will clear up the sound a bit and your amp/receiver won't have to dig as deep, which will keep everything running cleaner.

But, I went a while without a LFE sub and Yes, I set them to large. Movies can be a tad boring when theres no bass whatsoever.

You probably won't harm your speakers unless you have weak amplification, and start clipping.
