Starts at 19 mins. Look at this mic'ing setup.
They pointed the right mics to the passenger speakers.
Very interesting to see how JL position all those mics for spatial averaging. They also mention that not all those mics are weighed the same either. The video doesn't disclose all their secrets though.
This video just confirms why the system sounds like shit during all the times I've tuned using single mic location. The response changes drastically when you move the mic, especially higher freqs range. If you make drastic EQ changes to the higher freqs, they don't translate to what you actually hear in the car while your head shifts around the seat position.
The sub and mid bass won't change too much if you move the mic a couple inches but ~400hz-20khz will change. The higher the freq, the more it'll change due to reflections and beaming.
If you watched the entire video they also mention that they did some rear fill processing to remove the mono info from the rear speakers. I didn't even know that the TWK88 could do rear fill processing.
Interesting video. Just thought I'd share.
