gonk,I read in the 2 links you gave me(thanks!)that the xover in my tech 2000's are set at 80hz.Is this true,not very low. I read the manual...it doesnt say. Also, I think I'll try both ways as far as either using the 15" woofers as stereo subs or setting front speakers to small and setting the 950's xover at 40 for the fronts.Getting back to my question.... if I hook up to my 2000's via low level LFE "in" does that by-pass the xover that is in the tower? In turn,which would make the front speakers have the 40 hz xover per the 950?
