What’s the benefit of placing speakers like this? (diagonally at the corner)

Hello,

I am curious about the speaker placement.
(I try to upload a picture.... not working well...)

Here’s the link to Positive-feedback website containing the photo of speakers.

Let’s say this is the corner of the square shape room.


——————————————-
| [amp]
|  
| (Empty) (Empty) [Sp2]
|  
| [Sp 1]
|
|


(Facing toward the other side of corner)

Amp is placed at the corner of the room. (Diagonally)

Then Speaker 1 (Sp1) and Speaker 2 (Sp2) are placed diagonally too.

Amp and speakers face toward the other corner of the room.


I think this this is V.Rossi’s Audio show room picture from 2019 with QLN prestige 3 speakers.

What is the benefit of this kind of placement?

Jeff Joseph has been using that set up for many years at shows.  He was well known to have achieved great sound in many challenging show conditions and it seems to me more manufacturers caught on and you started seeing that off-centre set up more and more for speakers at shows.

Diagonal placement geometrically eliminates early sidewall reflections, which imo is highly desirable.  And assuming the room isn't overdamped, the energy which normally would have been in those early reflections survives to become beneficial later reflections. 

In a square room, I'd suggest setting up not exactly along the diagonal, but rather rotated a few degrees.  This way the woofers will each be a different distance from the room boundaries in the horizontal plane, which should improve the in-room bass smoothness a bit.

Duke,
Your recommendation seems to make sense with my experience.  I've found my speakers can sound a bit better when off-set a bit, so one being a bit closer to the listening sofa, and my slightly adjusting toward the further one, where I sit to maintain equal distance from the speakers.

Sanders set up their ESL's at shows diagonally.
