I did this test on my recent ScanSpeak build and the pink noise raising 71db, there was a jump from 84 to 88db at 35hz. Madisound had said Bass Box 6 Pro predicted an F3 of 35.5hz. I guess the ScanSpeak specs are fairly accurate. Interestingly (it can only be environmental) the speakers gained a db/hz from 10-17hz (83db to 89db) and then retreated back to 84db at 24hz where it stayed until 35hz. p -- pski real stereo doesn't just wake the neighbors, it -enrages- them..
