No subwoofer track?
Many people reported they could hear no sound coming from the subwoofer, and several argued this could be a 5.0 or a 4.0 mix.
However I had serious doubts it could be "the original 4-channel Quadraphonic mix" because I did get music on the center channel anyway.
So I looked for explanations and found an interesting article.
I understand from it there is actually no "subwoofer track" in DTS:
- DTS use a Low Frequency Effects "0.1" channel
- The subwoofer renders a calculated mix of the LFE channel and deep bass sounds from the 5 other channels
- LFE and bass in the cutoff range (set to 35-50Hz on my system) are not always needed in music
- DTS is still called a 5.1 format even when the subwoofer is not activated
This may partly explain the mismatch between the original tape box photograph in the liner notes and on the disc itself?
- The tape box 1970 writings seem to be anachronisms: "Left, Front/Center, Right & Rear" are only used by 80's Dolby Matrixed systems
- The disc mentions: "Front Left, Front Right, Rear Left & Rear Right" like were Quadraphonic systems
