I am using Promonitor 800s for rear (I guess a mistake as I thought that rears won't get used a lot - but after watching such movies, I see a lot of usage. Could have gone for 1000s for rears as well). However, 800s are doing fine.
Had a question about the crossover. Audyssey has set the crossover of these 800s to 90hz. But the definitive tech website says 100hz. Will using 90hz be harmful to these speakers - should I increase it to 100hz?
Welcome to AVS!
The Def Tech owner's manual for the PM800 says the lowest frequency it can reproduce is 57Hz, but doesn't mention if this is the -3dB point (F3). The Def Tech numbers are somewhat exaggerated to say the least.
When Audyssey carries out the in-room measurement by sending several chirps for each speaker, the result is correction filters being applied up to the F3 value. In your case it is 90Hz = F3 point as determined by Audyssey. Manually raising the crossover point above the F3 is fine as the filters are still active and applied to all frequencies above the F3. Lowering the crossover below the F3 is bad as Audyssey wont know what to do with those signals and will most likely get bypassed or unfiltered.
