I should explain how my pre/pro handles bass management. The HP filter is only applied to the mains, center, and surrounds (btw, I can set different frequencies separately for the mains, center, and surrounds). It dictates at what point to roll off bass to these speakers. The low pass filter is only applied to the sub; telling the sub when to start rolling off higher frequencies. If I were to turn the HPF off, the mains, center, and surrounds would be operating full range. As you can see my Anthem AVM20 offers some flexibility in tweaking the crossover region (slopes are not adjustable though).
Also, my pre/pro offers two independent speaker configuration modes; Music and Cinema. Within each mode you can set speaker configuration anywhere from 2.0 to 5.1. Also, bass management (HPF, LPF, distance, etc) settings can be different for Music speaker configuration and Cinema speaker configuration. Currently I have Music set up for 4.1 and Cinema for 5.1. Currently I have crossover (LPF and HPF) and distance settings set the same for each mode. Each input can be set to use either the Music configuration or the Cinema configuration. Of course inputs I'm using for video are using Cinema, and inputs for music only are using Music.
The Triax amp has no crossover filters, only gain and DSP program selection (button in rolls off steeper than button out; it's kind of a room gain compensation switch). The manual suggests button in for rooms <5000 ft3 and button out for rooms >5000 ft3. My space is about 5500 ft3, so I have the DSP button out.
The measurements I took are only mains + sub. Since my laptop doesn't have HDMI (I'm using the 3.5mm plug analog output to my pre/pro) I'm not sure how I could measure all 6 channels at once.
My mic is a UMIK 1 I bought directly from miniDSP. The calibration file shows offsets down to 10hz.
The reason I limited the graph at each end is that the response outside those limits converges. Different filter and distance settings don't seem to impact frequencies outside those limits. That said, I can either repost any of the above graphs (individually, or as a group) with an expanded frequency range, or I can take a new measurement when I get a chance with the current settings and an expanded frequency range.
Another clarification, I not interested in getting the best I can, given the limitations mentioned in my prior post, across several seats, just the prime LP.
PS - Just watched Star Trek Into Darkness. Freaking awesome! What a ride the Triax provided!
