Here is something on fib ratios:
So I took the idea from the Trinnov guide you posted to move my top middle surround atmos speaker from above the MLP (where they doubled as VOG for auro 3d) to top rear (right above the surround speakers so they now double as auro 3D surround height channels). Since I moved the speakers I took the opportunity to get new speaker wire (audioquest G-2 in bulk for the long run) and change the amp ( from a parasound Z amp to a Carver AV505), I also installed a new single VOG channel above the MLP. Now my center height, VOG, and top rear speakers are all being driven by the same Carver 5 channel amp. So I fired it up after redoing my calibration and everything sounds smoother. Before I could slightly localize the top middle speakers and now in the new location they blend much better forming that nice immersive bubble. It was a bit of a pain running the speaker wires but it actually looks better to. I’ll need to rewire the new VOG channel next week, I ran out of cable. Well worth the effort and thanks for posting that guide 👍
you are welcome. great to read that the guide helped.
helped me too.
i had been all ready to use the Dolby Atmos ceiling pattern then Trinnov convinced me to switch and i'm very happy too.
