[QUOTE="Phil Graham, post: 42427, member: 430"] Re: SMAART Learning: Magnitude traces from room tuning - 2 Marsellus, I would take the subwoofer response of these plots with a grain of salt. First, there were two separate subwoofers spaced far apart, and these measurements were taken at multiple locations that were assuredly in and out of lobes. My summary report to the venue shows 2 out of band eqs cuts on the sub, 1 in band cut, a 4th order lowpass, a 1st order allpass, and a 4th order highpass. I would say that in these church environments where the levels are typically 90dBA or less, 6-12dB more sub than tops is typical. I have certainly tuned systems with more LF haystack than this, and with less. [/QUOTE]
