No, total waste of time. Why not just move the speaker into the middle of the room?Can i do a makeshift anechoic chamber using a cardboard box stuffed with either dacron or fibreglass and make the measurement ?
Depends on what you want to measure. If you are only interested in the response of one drive unit then you can measure very close up. If you want to see how the drive units integrate in a multiway speaker you usually need to be at least 1m away (sometimes further, depending on the separation of the drive units and how the designer has set up the crossover). For more detailed info and tips on measuring speakers you are probably best to post in the DIY Speakers forum.While searching i came across 2 methods of placing the mic. One is near the speaker driver almost touching and the other is 1m away from the speaker. Which would be better ?
