I thought I would put this question in this section since it is directed toward all current and previous Outlaw receivers and pre/pros, as well as most other manufacturers’ similar gear.

Would you say that in general, when the speakers are set to something other than large, the subwoofer signals are removed from the full-range of each channel and mixed to the sub output before the delay settings affect each individual channel‘s output?

In the case where surround sub frequencies are mixed back to L+R channels set to large, then, if the above paragraph is true, the sub frequencies' delay would match the fronts.

If the sub frequencies are removed and mixed after the delay settings, such as when one is using an Outlaw ICBM or similar device between pre/pro and amplification, then potentially marginally out-of-phase mixing of the sub signals may occur. The effect of this may be negligible if the difference in delay settings is small - the wavelengths below 80Hz get long - and room acoustical effects and/or standing waves would contribute much more to introducing irregularities in the lowest frequencies than a slight shift in signals prior to mixing for the subwoofer output.

Information and comments welcome.
