Advice on acoustic room treatments for home hifi

[chych7]

Since this isn't a dedicated room with space for lots of acoustic panels, another (expensive) path to consider is Lyngdorf RoomPerfect. Supposedly you don't need room treatments with it (says their marketing dept.), but some of the REW spectrograms I've seen on it does show improvements to RT60/reverb, which DRCs like Audyssey/Dirac do not achieve.
