Ill give it a try on the 626, since i am too lazy to carry the RM30's to my listening room
Did you sell your kit for the RM40's yet?
-Flo
626 (& even rm30) may not be as noticable, as they are much smaller than your divas, & may not load the room as much, but i think you will still find the same issue of channel imbalance w/the your pathos. especialy since your substitute amp did not have this issue. curious - did you try swapping channels of the substitute amp to see if it got worse, or stayed the same?
re: my rm40 kit, still no sell.

i can't undertand why someone wouldn't wanna "roll their own", w/a cabinet narrower at the midrange ribbons - it would make for a speaker much better than the rm40, as even brian cheney admitted. for $2k, the kit is a great deal, imo. i really wish my personal circumstances dint prohibit me from building them myself.

know anyone in germany that may be interested? w/no cabinets, shipping would sure be a lot cheaper!
