So I have some questions.

I will be going with a 9.2 set up, including Heights & wides. My questions right now deal with the subs. I know they are not independent of each other. I also understand there is no sub Eqing, for lessening some frequency peaks.

First question, what does the Mcacc programming offer up to the end user as part on the initial set up? Does it at least set distances? Does it try to phase them in? Or is this done manually using a spl meter along with adjusting the phase control on the amp plate? With the Mcacc room correction lacking sub Eqing, is there a work around for perhaps some benefit on this matter? Right now I have no interest in purchasing any separate component for sub Eq.

The problem with any subwoofer in an HT system is that we are all, to some extent, limited in where we can place that sub in the room, so generally, if space allows it, it is always better to have at least two to compensate for any deficiencies in room sound. Once you set the volume balance and the phase between them and the rest of the speakers it should be fine so, really, you don't even need an SPL meter for this part of the equation. You can do that by ear better, especially with phase and, most often in this case, it is just a matter of personal taste anyway.

I have a Velodyne SMS sub EQ that I have used now for a number of years and even after a number of calibrations, even though it was showing a pretty good balance on the screen graph, in the end, I really didn't care that much for the sound because the problem with human hearing and an SPL meter is neither registers properly with frequencies below 50HZ and I really wasn't hearing those really low tones. I used the EQ primarily to boost those frequencies below that 50HZ level to my taste and to me it sounds better. This is where theoretical accuracy and taste part ways.
