 Who knows about low frequency room modes?
I've been looking into this room modes stuff and been thinking. If I'm off base here, someone please correct me. I've downloaded a room mode calculator and run a few dimensions. The way it looks, to get a low(~20hz) frequency boost (by way of room), one would need a a room with one dimension at least 25 feet or greater? By what I've read, putting a sub in a corner will excite all room resonances. If one would put a sub in a corner in room(20x18x8) all frequencies above 28hz would be excited making low frequency extension look nill because all other frequencies above 28hz have a large db increase. No matter what you do with moving the sub, the room is not your friend if it is smaller than 25ft( for low extension). I guess using bass traps would lessen the resonances and ultimately an equalizer would fix it.
Any ideas? Please chime in.
