The size of my LR is 20 by 12 Ft.Due to circumstances beyond my control,namely my better half,the speakers are placed 15 inches from the back of the long wall and approx 7-8 feet apart and at least 3 feet from either short walls.My "sweet"spot is on the opposite long wall equal distant from the speakers by 7 feet.The room is well upholstered by a couch and a love seat as well as carpeting and curtains.To tame the excess bass I was using a vintage computerized DBX 10/20 automatic equalizer harking from the "golden age" of stereo.Alas the DBX,which had done a fine job in normalizing the bass at my sweet spot, has gone on to meet "its maker" after long years of faithful service.There are no decent equalizers, parametric or graphic, being made now days so therefore my question about Audyssey for stereo.I am not in need of a HT receiver since I listen only in stereo.Is it possible to get the Audyessy system without having to purchase a HT receiver? Any help would be greatly appreciated.
