It is time for the ultimate TTD correction solution with Audiolense. For this I do not need to be concerned with latency, I will be playing content from my hard drive or blu-ray disk, not streaming from the internet. To avoid having to change signal routing in my MOTU 16a when I switch from Min Delay to TTD, I will reuse some of the previous full range set-up.
Here's the speaker setup window. My sub array will act as a single bass driver for each of the three front speakers.
Here's the input signal routing. I drop all the channels except LFE by 10 dB and then combine the LFE channel with the center (this is discussed in my subwoofer array thread). I do not use the 10 dB amplification of LFE in this case.
Here is the crossover setup. With the linear XO filters and TTD I have selected narrower filters than when using minimum phase XO. I have also set all bass XO at 100 Hz. I don't want my sub array to be -6db at the typical 80 Hz XO. 100 Hz gets me a better chest thump from the subwoofers.
I do not re-route bass from the surround channels. I let the surrounds run full range (mine are good to 40 - 50 Hz which is fine). I do not want to blur the sound from my front main sub array with those signals. The surround signals are intended to create ambience in the room, not compete with drums and bass guitar up front.
Here is the MOTU signal routing matrix. Input channels from the Audiolense convolver across the top, analog outs to my amps on the left. Three separate bass signals are mixed and sent to three subwoofers. To the mixer loop at the bottom and back on Main L at the top.
