Joel Posted September 29, 2011 Report Share Posted September 29, 2011 So I've got my AR90's refoamed and recapped. They sounded pretty good, but I thought they could be better. I looked around the web for advice on speaker placement, even found a site that had a formula to follow.I tried to follow the formula exactly. They sounded terrible. I tinkered with their placement, nothing helped. Finally, out of frustration, I pushed them back into the corners of the room. That was it! They sound fantastic! The imaging is wonderful- the bass is deep and strong. It was like a camera that was brought into focus. I have been listening to them for hours and hours- it's like I can't stop, they sound so good.Is there something about the AR90's design that makes it so that they don't follow the normal rules for speaker placement? Could it be the side firing woofers? Or is it something peculiar about my room?-Joel Link to comment Share on other sites More sharing options...

To close to a corner and you cancel out one of the bass drivers. In a nutshell, the these speakers do best when wall coupled. I'll make a dangerous assumption most speakers with side firing woofers were intended to be wall coupled. Link to comment Share on other sites More sharing options...
