David,

I've tried the Convolution filter for a bit of correction. I have it running on a couple of Bluesound systems to great effect, especially on a Powernode with bookshelf speakers installed in a French dresser - really sorts it out! I didn't trust myself with doing the EQ myself so this uses a microphone to measure the response for correction.

I tried on DSPs too - mixed results although that room is in a state of development so I don't have a final setup yet to correct/measure (if it needs it).
