The bass always have been sloppy and laconic, but he pressure in the room sinks the middle of the room like in a time delay fashion, if you notice the target base line was hitting 200 and then he slid it back to like the 155-160 region, this fixed what all along even the top acousticians thought was a condition of the 90 year old wooden mansion. Well Mike tighten that bass and time aligned it dead on where it sounds like a top room.
Also tightly packing the mics around one seat made a huge difference not only in that seat but the general mlp area, when those of you upgrade to dirac 2 I recommend setting a memory for just one seat.

At that time I was focusing on DCI Projection but apparently I had the skils to do great acoustics and select/site great speakers to where:
