Interesting subject. I am primarily a OB dipole listener. I would like to have a reference stand mount speaker for rotation. Whatever chosen will be electronically crossed over to either a Linkwitz Lab equalized "H" style open box woofer or GR Research "H" style servo woofer. Using a general 60-120Hz crossover point. So lower octave of so is removed. I especially like the Pulsar 2 even when used full range. Limited experience with Dynaudio, Focal and TAD. Feel the B&W 805 D4 is in the running. More opinions. I am blessed with two rooms; 450 sq. ft. and 900 sq. ft..
