Home Speaker Asylum

General speaker questions for audio and home theater.

I measured my 626R...

and my 3 meter measurements, averaged over a 36 inch listening window, looked pretty similar in shape and magnitude to the on-axis response in these measurements from aout 300 hz. and up (except for the dip at 12K-I found no sign of that). These were third-octave, taken by RS meter, and corrected. I find these measurements to be quite adequately accurate. My Revel M20s are produced with a +-0.75 db tolerance, and while they might be "smoother", the VMPS are clearly more detailed and accurate. I don't know how the "in room" response curves taken by Dennis Murphy were done, but neither those curves nor the owner's description of the sound on the site bear any resemblance to how mine measure or sound. I suspect bass mistuning is an issue here, or possibly out of spec units.
