[QUOTE="Ivan Beaver, post: 24034, member: 30"] Re: Why Do TEF Systems read 3-5 dB high ? I don't have time to go over all the details of your post-but will hit a of them. The TEF is calibrated using a known good claibrator and then using an automatic level setting. Then that level is checked on the RTA display with the calibrator still attached to see if it matches the calibrator level. I brought up years ago that the calibration was off during at least one of the Tulsa shootouts. I don't knwo where BFM gets his measurements from, but others have brought up the fact that various other loudspeakers measurements look "off". The curves look as if they were hand drawn with a crayon. I think there have been a couple of different Growler versions that have shown up at the shootouts (I could be wrong on this). I believe the origional was a little louder, but a latter one was flatter. Of course you can change the calibration and make it whatever you want. [/QUOTE]
