I am planning on adding a pair of subs to my room.(front/back walls axial modes) I will have them professionally calibrated/installed. Everything will be done inside Jriver and out an Lynx AES16 (crossover, delay etc.), then to multipe DACs with unified digital volume control inside all DACs.
I am told that so called "group delay" can be audible at lower frequencies; below 50hz. If that's really true, then it seems to me that one of the specs that would matter most would be lowest group delay (fastests subs; cringe Nyal Are there any valid measurements available that compare group delay? I am considering JL Audio, Velodyne and Procella. I am also interested to know how DSP on the sub affects group delay (eg. Low pass filter) and whether some subs allow the user to defeat said dsp so as to "speed" the sub up.
