Sub best at high crossover?

If you're asking what would explain your observation:

Your sub is providing smoother response up to 200hz than your mains are. IME, that will usually be the case for a well set-up subwoofer. No mystery there

You're no longer using it as a, "SUB." 200Hz is close to a piano's Middle C(264Hz). BUT- As long as it makes you happy..... You may find this of interest: (http://greenboy.us/fEARful/frequencytables.htm)

What is your preamp source? If its a home theater processor then have you may have selected a crossover point in the setup menu in the processor. Taking the sub's crossover out makes sense because two crossovers in series can interact which causes problems in most cases. My Velodyne has a toggle switch which can completely remove it when fed via a HT preamp/processor.

If you are using a stereo preamp then taking the crossover out in the subwoofer would typically result in too much bass from my experience with my Velodyne 18" subwoofer. But if you like it that way enjoy.

I believe that you need to take measurements to setup a subwoofer correctly and then fine tune via listening. Just my two cents worth.

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!
