Fine Tunes #48

In his first e-mail to "Fine Tunes," Rafael Teodoro (RBT@wolfenet.com) addressed a subject that Mark Gdovin, that faithful frequenter of the Stereophile soapbox, had already brought up. Mark had gone so far as to give readers sage advice from his brother, a materials engineer, regarding the dangers of applying Armor All to speaker cones and surrounds.

Sometimes tweaks take on a life of their own. Take the one of using Armor All to keep speaker surrounds from drying out, which you can read all about in the November 2001 "Fine Tunes No.41" I recently got another e-mail on the subject from Dan Mazza at Arizona Hi-Fi, who agrees with Mark Gdovin's objections to using Armor All. (Read Mark's comments on the entire issue in the readers' letters linked to "Fine Tunes No.41.").)

Fine Tunes #39

Last month I wrote about lasers of various pedigrees, so useful in marking walls to the sides and behind the listening position to ensure that your loudspeakers are toed-in, level, and equidistant from the sweet spot for best soundstage, imaging and focus. Using small Avery stick-'em labels makes this a snap. I've converged the tweeter axes of my JMlab Utopias somewhere about a foot into the wall behind the rearmost of our two listening chairs, and use two Studio Traps and a single Argent RoomLens between the speakers to cancel and damp the near-rear-wall reflections. With just a jiggle of the chair back or forward, suddenly I'm there.
