Today I had a little play with a basic SPL meter and some test tones and was reasonably gratified that the expected room modes were present at the calculate frequencies, so I can work on those. What was a totally unexpected was an -18db hole at 45hz! Any idea what causes this and if anything can be done about it?

The speakers are 7 Pi's and the room is 17.5 x 12.2 x 8.5 (LWH)

To be honest I didn't spend a great deal of time on this (to boring when there's music to listen to) so may have to revisit the exercise again sometime.
