What can be done to further improve sound in my Home Theater? I ran Audyssey, then ran REW with MiniDSP and UMIK-1. Did the filters for my 2 Dayton Sub1200 and a smaller Jamo. Please be kind. It is my first attempt
Take another 2 measurements 6 inches on either side of where the mic was. You don't want to correct based on a single point.
Gently cut only peaks, ignore sharp dips. For example only, using your single measurement above, a cut around 5-6db centered around 90hz, 55 and 54hz. It need not be "flat", it can slope upwards as you go lower towards 20hz. Listen with familiar music tracks each adjustment, to make sure you're not overdoing it.
