[QUOTE="Loren Jones, post: 4442, member: 829"] Hi, Quick theoretical question. In a system with a traditional left and right sub, each driven off of a separate output of the DSP and therefore each with its own amp, what will be the effect in terms of acoustic output of decreasing the DSP output to each of the subs by 3 db? Will it be a 3 db reduction in the LF output in the room, 6 db reduction, somewhere in between, more than 6 db or less than 3 db? The subs are about 40 ft apart and LPF is at 80hz. I suspect the answer is that it depends on where you are in the room and what frequency you are measuring but I don't know enough acoustics to be sure. Obviously this question is more for theoretical understanding as the level of the subs will be adjusted by measuring and or listening, but I am just trying to understand. I recently decreased the outputs from the DSP 3 db as described above and it seemed like the LF output in the room went down more than 3db. I don't have very accurate measurement tools or skills so.... Thanks, Loren Jones [/QUOTE]
