Diffuse Front Wall? Absorb rear wall?


I'll research existing threads, but quick basic question --- is it a basic tenet that I should use a diffusing approach for the front wall and an absorption for the rear wall behind my listening position? I bought a wall rug, put it on the front wall, and though it seemed to quiet the room down in some good ways, it seems to have sucked some of the energy and sparkle from the soundstage. thanks.

Diffuse the rear, absorb the front, as a general rule. Windows should always be absorbed.
LEDE rooms are the other way around. Even in relation with room acoustics, most folks here will opine that anything goes so long as you enjoy the sound and are "emotionally involved".

LEDE rooms are a bit passé as computer programs are now used to make a finer analysis of each room.
The front is a matter of taste but a live front end is often more pleasant sounding or lively. Generally it is best to absorb on the rear wall behind the listener...if you sit with your head near this wall then you need diffusion behind you for sure.( normally you should sit 38% of room length and at least 3 or 4 feet from a wall.... 8 feet or more is much better)
LEDE was out of the recording industry in the 60s. It was for control rooms, not listening rooms. Go to this page. Click on the article "on the soundstage" by Chris Huston on the right hand side. This will give some insight into the differences of a control room and listening room.

He is an amazing source of information--and a great person too.
Thank you for the input to all. Variety of opinions and experiences. Subjective hobby. Appreciate the insights. For what it's worth, the last couple nights I've been listening with the rug behind me (apprx 3 ft behind me in a 22ft room -- speakers are appx 8 ft off of the front wall --- and I now have a row of ASC Sound Panels and one Tube Trap in the middle across the front wall). Pretty pleased with the sound. Think I need some basic absorption stuff on side walls now, and may be close. Thanks again.
