Bravo Erik on your common-sense post!
Funny, I did just that this weekend. Went to a thrift shop, bought $6 worth of clean, washed and bagged blankets.
(I have posted before about my Vandy 2Cs being hot in the treble).
Well, after hanging a blanket on the front wall, the side walls, and the rear wall covering up the first reflection points, I sat down for a listen...
Amazing, really amazing!
Bass, good, clean, deep bass.
No more treble bite.
Soundstage deeper, wider and taller.
Sounds like a different and much more expensive system.
Midrange clarity, actually top-to-bottom clarity massively improved.
Kudos! Excellent post!!!
