Home Speaker Asylum

General speaker questions for audio and home theater.

Sean: The width and depth of the felt ring makes...

quite a difference. Sometimes just a little thin ring (like 1/8", or less, wide is all that it takes. I found any ring @ all to be too drastic a change on a pair of Castle Isis speakers and instead ended up placing tiny dots of "wool" felt over the two woofer mounting screws which were adjacent to the tweeter (this cleared up a hard artifact that I was hearing @ louder volumes).

It can also work with recessed tweeters as you are trying to dampen the edge surrounding/blocking the tweeter (such as I did with a pair of Minimus 7's). I used a 1/16" strip on the inner edge (formed into a circle) and a 1/2" flat ring on the front of the baffle.

Another easy tweak used by a guy (THOR) on his single driver speakers was to drape a piece of single ply tissue (TP) in front of the driver (which was a bit hot sounding).

My Twins have a 5/8" thin felt ring around the tweeters that I once covered with glossy paper. I kind of liked the brighter sound as our room is a little dead, but my wife did not care for it.

Anway, it's good cheap fun as squares of wool felt are available @ fabric stores for a buck or less. I also use this thin felt to adjust the VTA on my TT (slip in an extra disc of it for thinner LP's).
