[QUOTE="Ampdog, post: 38969, member: 144"] Carefully here from me; I have little experience with this sort of thing and am likely to learn more than giving advice. But the above point is valid. In rooms with pronounced dips/peaks low frequencies need a finite time to build up. Thus the response with music might not be as bad as a frequency response graph indicates. But then, where was your sensor (meter) situated? The bad news is that all 'enclosures' have standing waves (as you might know) - no matter where you stand, something will be augmented and something cancelled. Have you tried 'recording'/measuring at different places? At all: To what degree does a bass trap improve matters generally? To what degree is it largely moving the peak/dip pattern around? I will have this problem soon; my loudspeakers will be situated in a fireplace of sufficient volume. Good news: No cabinet vibration; solid brick. Bad news: I cannot move it around. (In my case no sub; the l.f. radiators have fr at <20Hz; huge 30cm long-throw devices.) Not trying to put a foot in your door, Robert E, but as said advice will also be vauable to me. [/QUOTE]
