[QUOTE="Don Boomer, post: 82686, member: 633"] Re: Loudspeaker Sensitivity Hey Michael I'm not clear ... are you wanting to measure a "driver" or "speaker system"? If the latter then mic position can make a big difference. Manufacturers don't often specify the mic placement. Unless specified the mic is usually placed on-axis and in front of the HF driver. But sometimes it's taken on the "design axis", typically half way between the woofer and tweeter. In this case the distance of 1 meter is likely a lot closer than anyone is actually gonna listen to the box and there can be big differences (peaks and dips) with only a small change in the vertical position of the mic.
