Here was the response in my last room when initially setup by Mark:
In my current room, these are the raw measurements (eerily similar to my last room).
The black line is the uncorrected response, no smoothing, and all 4 subs running off of a single output on my Integra, so no delay of the rear subs. The primary improvement of adding the delay (yellow line) is above the crossover point to the center/mains but in so doing, gave up some (uncorrected) response below 20hz.
To get this output, I had to have some serious therapy to work through my audio OCD. For the first time in all of my years in audio, the room is not perfectly symmetrical with respect to equipment placement because my two rear subs are not symmetrical to the MLP (they were in my last room but door placement made it not possible in this room). Prior to having Mark in my home 5 years ago, I had no clue how to do any of this. He is the main audio setup guru.
When you start off with incredibly well designed subs, placed in the room with the knowledge gained from the guy who designed the subs and then use the integration "tricks" passed on by the guy who designed the subs, this is what you get after room correction (No smoothing - MLP);
I only have one row of seating so, in one sense, we are in many ways, comparing Apples and Submarines!! If I had to get this kind of response in three rows (or even two), I would probably (just call Mark!).
Jeff: With 6 SubMersives in that room, optimized by Mark and then played through the Datasat, you should be in audio heaven.
I am very much looking forward to your impressions.
If I recall, the Datasat has the ability to have more than one set of Dirac filters stored. So when it is just you and your wife, you can correct for the sweet spot but when you have guests, you can use another set of filters. THAT should be very nice.
I am very excited for you. Should be amazing.
