Just wondering what I could use in terms of amplification for my DYI OB speakers. They do dip to about 4.5 ohm around 60HZ, but they're between 6 and 8 ohm from 85HZ. Phase is very well behaved above 60HZ ( pretty flat between 0 and +25 degrees). My room is large (9' ceiling. 20 X 35 ft).
I'm all ears for your recommendations.
