Re: 12" OS zvukovody
BTW, this is my last measurement of the raw WG (DE250), 5ms window, no additional smoothing (Holm can't do gated smoothing. Xover now can, but I'm lazy):
(blue = Abbey's, red = mine, ~30deg)
12LW1400, cca 4ms window (need more free space, maybe at our local gym soon):
I was a bit surprised by the amount of woofer's energy up to 4-5kHz. 12TBX100 falls like a stone above 1kHz or so, which is probably a good thing. Anyway, my aim is 24dB/oct crossover so that is quickly inaudible.
Woofer and "tweeter" sensitivity comparsion (with plug installed, which is about -2dB):
