Short different question inside here:

If you don't use SLICE rears with ArcTan but the "native" ones, is there any possibility to wrap the rears?

Yes. With SPEC 4.2.1, ArcTan has an "Adjacent Speaker Control" option where you can set "Wrap Rears" to On. I normally use a value around 0.30 for "Adjacent Speaker Level".

I believe this feature was also available with SPEC 4.0, but you should really upgrade to SPEC 4.2.1 with ZAG.

I am using 4.2.1 but I have adjacent speakers set to bypass as I am only using the blend controls which only have a wrap option if you chose the slice rears. Understand?

why are you bypassing "adjacent speaker," though? i still think it can be extremely useful for filling out the sound when using blended rears. i've never bypassed them on any conversion.

If you've got a good reason to bypass them, though, then the only way you're going to use WRAP is through the Slice settings. you're correct.

In ArcTan the rears are "wrapped" if you have the "image width" set to 360. The are not wrapped in you have the image width set to twice the angle from center to your left surround speaker.

You can test this by setting the image width to 360 and then disconnecting one channel from the the audio file player to SPEC. If you then listen to each rear speaker you will find some audio in both. Lower the image width and the sound will shift from both rears to one only.

I'll test this but I'd like to add another question. If the rears are fully wrapped I thought there is the same sound in both rear speakers. Testing this I found that there are still different parts in each speaker, e.g., backing vocals stronger in sl, weaker in sr and the guitar vice versa.

That suggests the the sound weren't panned completely left and right in the original stereo (hard panning).

Yep, then it really seems to be because of the panning in the source. If I want to have the same (or very similar) content in both rears, is there an easy possibility to do so, e.g. because even with wrapped rears that crappy lead guitar is overpresent in the left rear speaker? If I just reduce the sl volume the balance is gone, so . . . ?
I could fumble around with some gains in the layout but maybe there is a more decent way of doing that.

Have you tried the different "modes" in ArcTan (Sum, Across, Diagonal)?

Hard to know without listening to your source but I guess you could use ZPan to move the rears closer to each other.

Also in extreme cases, I have re-wired the outputs of SPEC (or you could do it with the ZPan controls) to swap SR with C, etc.
