Hi all, I recently completed work on both a subwoofer and front speakers: Mains: http://www.avforums.com/forums/showthread.php?s=&threadid=125302 Sub: http://www.avforums.com/forums/showthread.php?s=&threadid=122804 However I cannot get them to integrate properly. The fronts are astonishingly good speakers for the money they cost to create and therefore place greater demands on the subwoofer to integrate - or at least thats my view at this point. The sub on its own sounds pretty heavywieght and is certainly not subtle, definitely more HT muscle than hifi finesse. You see whats happening is that the sub completely ruins the sound from the mains, how? Well the treble detail disappears even when the sub is set to a conservative level. If I turn the sub on during playback its as if a mask has been applied. What I don't understand is why is this happening?!? The sub is crossed over far lower than any treble frequencies. Aside from the mains and sub my setup is as follows: Lexicon MC1 Chord SPM 1900 5ch power amp Settings are: Fronts: 40hz (controlled by the MC1) Sub: 40hz (controlled by the MC1) I've tried various crossover setting from 120hz all the way down to 40hz which currently gives the best sound but still dissappointing. How can this be fixed or is the sub design at fault?
