Thanks for response.
Wolf_garcia - I usually do trust my ears, thanks, but sometimes I am not quite sure, especially when the case is not so clear, plus it goes against the accepted rules...so thats why I am asking.
Tonyangel - agree, directionality and too wide range may be problems, but I don´t hear much of them at 199hz in my room. Instead the music has more dimensionality, depth especially, and sounds a bit more relaxed.
Emailists - yes there is a mid-room suckout, which is part of why I use the sub. I have measured, this is not a case of upper bass hump that I like. I run it at 199hz but turn it down, ok? The effect is mainly what it does to the rest of the spectrum.
Imhififan - yes, the sub´s equalizing is the suspect. A slight tension and flatness to the music. Subtle, though.
Martykl - I have the same result with different pairs of speakers. I had Dynaudio Consequence, some of the best there is regarding bass. So I don´t think it is because the sub does 200hz and below better than the main speakers (ok, from 30 or so, but this is not the main thing).
Bob_reynolds - yes, logically 35 or 45 or so would sound best with the speakers I´ve used. Only it doesn´t. At 199 the music feels "freer", more "here". Note, I never cut the low end from the main speakers, never liked that type of connection.
Rodman99999 - interesting link, but according to the table an 18 inch driver only becomes "undeniably directional" above 903hz. I am not quite there! It is perhaps slightly more directional, but that is less of a problem than the electronic glaze when I use the crossover.
Dms1 - too loud if taking out the crossover, yes, simple remedy, turn it down! I have it on 4 or 5 or so! (The preamp is the Aesthetix Io Eclipse).
So thanks all, although I remain a bit curious why other owners haven´t discovered this - if you have the chance, try it out!
