I permanently use an Ambio box with my Beomaster 8000. I chose S45 speakers for that function.

It does bring a sense of atmosphere.

It’s fake but quite pleasant.

Ambiophonic is the same thing as what was called Hafler Dynaquad. I made one of these boxes about 40 years ago and also found an old Dynaco box later I played with. What this does is take connect the positive speaker level signals, Right + and Left + to a pair of rear speakers (usually attenuated some), which are then outputting the difference between the two channels, L - R. The original Dolby Surround was this for the rear channels with a 20 millisecond delay applied, which then evolved to this plus a L+R as a center channel.

As Cleviebaby points out, it generally works best with simple recordings, two mics, in a place that has real reverb and acoustic space, like a concert hall recording as opposed to a studio album or multi-mic'd recording, but it depends a lot on the recording. I've heard some pop/rock tracks that use a lot of phase manipulation produce interesting effects

Worth experimenting with to see if you like it, it's inexpensive and fun. I didn't wind up using it much at the time.

Sounds fun- not so much inexpensive. Is there a cheaper solution than buying the official B&O adapter?

I dont have any kind of adapter. Just two old Philips SQ5060 speakers connected together via - tabs and from + tabs to Rl+ and Lf+ on amp side.

Edit: Correction, I do have B&O adapter, but not in use because I too lazy to adapt my wiring to fit it :D

Is there any way you could send a diagram or some other visual aid? I’m somehow too stupid to decode what you mean here, ahah

Thanks so much! Just to be clear, if I wanted my ambio speakers to be wired to my speaker B terminals (so as to make the whole system toggleable) would I have to short the 2 negative terminals?
