I just posted this reply in the video section, but it really belongs here:


Less than $100 will buy a real nice audio generator that can reveal and POINT DIRECTLY TO (otherwise almost impossible to locate) all types of distortion causing stuff in your listening room. Room rattles, loose wall panels, junk bouncing around on shelves, loose window panes ;), etc etc etc. Paintings and framed posters on the wall are almost always a culprit; some make a terrible racket! Mine all have pieces of foam on the back now.

Some parts on speaker cabinets themselves work loose, not to mention the drivers themselves.

There are tons and tons of these things on ebay. Try a search for:

"(audio,tone,function,wave) (generator,oscillator)"
