Some of you may have run across the audio snake oil assertion that speaker cables are directional.
...There are speaker cable companies that claim to have "oriented the copper crystals so that it will sound better in one direction" than the other. They print an arrow on the cable. Utter bullshit. Audiophile snake oil.
Those dang electrons just CAN'T be convinced they have to go BOTH ways!
Don't know about them cables but I got some cans of Audiophile Compressed Air for blowing dust off tweeters before critical listening sessions. The negatively charged ions in the cans will neutralize the static charge built up on tweeters and restore the colorless high freqs to their natural pristine state. Twice a week is recommended for most users.
$29.98 per 12 oz can or $220 per case of 12.
It's my understanding that the directional characteristic of these fancy cables will allow you to actually hear the DC half on AC/DC records...Material that no one has ever heard until now.
Oddly enough, The photo in the original post is actually correct. I work for a place that manufactures heat exchange vessels. The heads on these vessels are held in place with large (3/4" to 1-1/4") bolting which employs washers. The washers are typically a "punched" product. One side has a flat (almost sharp) edge. The other has a slightly rounded edge. The nuts used are the same way. Flat on one end, rounded on the other. The rounded sides of the nut/washer always face each other when assembled. This prevents them from digging into each other when high torque is applied to them.
I have always put the stamped washers rounded side up against the nut. The edges on the other side have a tendency to dig into the surface and help prevent the nut from working loose. Kind of like a lock washer. Not as effective, of course.
No fiberglass flanges here. All CS or SS or some other exotic steel alloy. I Think they use a 90 degree star pattern. Usually raised face flanges, Durlon gaskets.Well, then you must know that the torquing sequence for a Fibercast flange is different than that for a carbon steel flange…and that you must use full-face gaskets on the former.
OK, you asked for it:

So you'd better be sure when you twist those direction cables onto the speaker terminals that you use the right amount of torque in your wrist and in the proper sequence.
