Illustrations[edit]

I believe it might be beneficial to this article to include some diagrams and/or schematics to visualize this circuit and its basic function. Gutten på Hemsen (talk) 21:32, 21 June 2021 (UTC)[reply]

Is the decoding matrix correct?[edit]

In the circuit diagram given in the article, the rear loudspeakers are connected in series, so each of them only gets the half voltage. Thus I think the matrix should be

Hafler decoding matrix	Left Front	Right Front	Left Back	Right Back
Left Total	1.0	0.0	0.5	-0.5
Right Total	0.0	1.0	-0.5	0.5

The article currently shows the following matrix:

Hafler decoding matrix	Left Front	Right Front	Left Back	Right Back
Left Total	1.0	0.0	1.0	-1.0
Right Total	0.0	1.0	-1.0	1.0

In order to achieve this, the rear speaker would not be connected in series but in parallel as in the drawing on the right.

If the rear speakers are wired in series, the sound coming from the rear can never be louder than that coming from the front, which would be a flaw imho. But then again, maybe this is the difference between the Hafler circuit and the Dynaquad.

Could somebody please check this issue? -- Sloyment (talk) 22:56, 27 June 2024 (UTC)[reply]
