[QUOTE="Ivan Beaver, post: 24341, member: 30"] Re: Why Do TEF Systems read 3-5 dB high ? I wonder how they window out the floor? In order to use windowing down to a low freq, the window has to be large. This means you have to be in a LARGE room. . Anyway-I would love get a sub with a know measurement condition (whole or half space) and a published response chart (that has dB levels-not a 0 and then +-), to do some side by side testing. For what it is worth, Pat Brown (Synaducon) has pretty much the same SPL results when he measures our full range products as we do. I am not sure what system he is using. He has pretty much all of them [/QUOTE]
