Change of plans - these will be going in my home office, not the living room. Anyone want to hazard a guess why?
Some measurements with REW - take them with a grain of salt, as they were measured standing in my garage next to the open garage door, with only ballpark mic placement, speakers were a couple feet away from shelving on one side and a table on the other, yada yada. I just wanted to see approximately where I stand as far as effectiveness of the crossover and how the speaker components and build were behaving.
Test setup: Behringer ECM8000, AudioBuddy preamp/phantom power, UCA202 USB sound "card", laptop, Lepai TA2020 amp.
mic'd from 3' away, with mic vertically aligned with middle midwoofer:
mic'd from 6' away, with mic vertically aligned with middle midwoofer:
mic'd from 6' away, with mic vertically aligned with midwoofer 2nd from top (53"):
comparison of L speaker on axis, and ~30 degrees off axis on either side:
So dips around 1800 and 5500, but nothing horrendous I think - will remeasure when they're actually in place in the room, near wall boundaries, and then deal with EQ. I was actually pleasantly surprised that the midwoofers measure as well as they do on the low end, was expecting to have to cross them over to sub fairly high, but maybe I don't need to.
Crossover is 3rd order Butterworth @ 4000, fwiw.
