I found that THX 80hz stinx.I have an EAD Ovation-8 and use 65hz.It is the point where my minimonitors roll off anyway.I would rather my mini's reproduce 80hz than my subz.
You may want to check Harman's web site as there are a few technical articles by Floyd O'Tools team discussing the subject. I recall Richard Vandersteem talking about how a subwoofer needs crossing over an octave above the main speakers -6db lower limit, but I'm not sure about that. Hopefully this will get you started. Happy Hearing, Keith
