[QUOTE="Shonver, post: 94428, member: 34"] Are your drivers in a sealed enclosure? Ported would give you a second peak. Ported would extend the low frequency response of the Super8. You can try making an average of x measurements to get rid of the noise. If the noise is random, the average of x plot will reduce the noise. But if it is periodic it won't go away (I'd guess that sample rate conversion error would be periodic). It has been a while since I used SW, but I'm almost certain that you can get an average of multiple measurements. Also try measuring to sine wave sweep (as opposed to MLS), as it has a higher signal-to-noise ratio (again, I hope I'm remembering correctly that SW can do this). [/QUOTE]
