You will never come close to a flat response in your listening room, nor would you want it. If you are looking for bass tracks to adjust your woofers on the Triton Ones, here are my recommendations on what I used on both my Triton Ones and Triton References for the tightest and cleanest bass and the proper level:
Dead Can Dance, "Spiritchaser" Listen to the first song
Kim Simmonds & Savoy Brown, "The Devil To Pay" first song Ain’t Got Nobody
Stanley Clark, "Journey To Love" First song, Silly Putty
Bob James & Earl Klugh, "Cool" First song
Grand Funk Railroad, "Closer To Home" Sins A Good Mans Brother
The Who, "Live At Leeds" Magic Bus
I'm sure others have their favorites as well.
