Speakers on the long wall


My Vandersteen 2Ci speakers are now on the long wall of a 13' x 20' room with a 7' 7" ceiling, roughly centered on the wall and about 10" from the front wall, with a TV between them. The listening position is about 9–10 feet away, on the opposite side of the room in front of three windows, and one of the short walls has a 6' opening into the kitchen.​

In a previous setup the speakers were on the 13' wall and sounded excellent, but returning to that arrangement is no longer possible. With the current long‑wall placement, the sound is shallow, a bit lifeless, and the soundstage is poor. This seems to point strongly to room interaction.

This seems like the kind of room many have successfully tamed with careful placement and treatment, so practical advice on how to proceed with room treatments and positioning would be very welcome.

By chance, are there any plans on how to design or make diffusers or absorbers?  Although when reality sinks in the other half will want something "not ugly".

I thought these diffusers were attractive and from a reputable company and not hideously expensive…

My room is 21x12 with a similar height ceiling with the same sort of listening distance from the long wall.The listening seat is a large leather sofa. Only one door to the left of the listening position. The ceiling is coved which improves the room accoustics

Speakers 12" from the wall and about 6.5' apart and TV in the middle.

The speakers are YG Hailey 2.2 and Vitus SIA 030.

It all sounds great and my suppliers have commented very favourably on the sound quality. One who is not a YG supplier tells me mine is the only system he has heard with YGs that impress him. He couldn't put his finger on it precisely but suspected it was the combination of the room and the Vitus amp

Hope that helps

My upstairs living room is approx 28 x 16. I’ve never really had good luck with the speakers on the long wall in this room. Doesn’t sound bad by any means just way less good than the short wall. I’ve tried with multiple speakers big and small. Finally gave up and put the system back down in the basement since the short wall is not feasible long term. Never really had the chance to play with room treatments too much but that might have made a difference.
