LOUDSPEAKER CONE TECHNOLOGY: Ever wonder why loudspeaker designers get so excited about woofer cone materials like Kevlar, aluminum, paper, sandwich cones of carbon fiber, and other materials?

PS AUDIO / Paul McGowan Their excitement comes from understanding the challenge of making an air piston (which is what a speaker driver is) that can start and stop in perfect synch with the instructions from your power amplifier. To accomplish that feat one would prefer a cone (the piston part) that had zero mass […]

THE ILLUSION OF BEING RIGHT

PS AUDIO / Paul McGowan I would suggest that throughout time it’s rather commonplace to hear people discounting or dismissing the experiences of others when worldviews do not match. Sometimes that’s helpful. If I see the world as flat and declare it so, you can help me by explaining the well established facts. That’s a […]

ALPHASON: Titanium tubed arms – HR100S or a Xenon?

I’d always fancied one of Alphason’s titanium tubed arms like the HR100S or a Xenon. The HR100S tends to be quite expensive (too much for a punt anyway) and I can’t say I’ve ever really heard one at its best as they mostly tend to have been wired with the horrible vdH cable throughout. A […]

Pasadena nostalgia: Mr. van Halen, the Leslie speaker cabinet, Jackie Robinson, JBL, General Patton and … John Mayberry

Editor’s note: Earlier this week we asked Howard to invite John Mayberry to be a guest contributor here. He’s agreed. Unusually for us we didn’t set John a series of topics. Having read some of his material, all of which we found engaging; his writing being somewhat iconoclastic, we decided to let him write on […]

AUDIO CABLES: There are any number of ways to maximize the sound of cables.This multi-gauge method is but one.

PS AUDIO / Paul McGowan If you had a chance to read my post of several days ago titled The Bypass Cap you might have been thinking it was about headwear. Or, you might have gotten my analogy of using a super tweeter to augment a standard tweeter. Here’s another for you. If you were to take […]

CASTLE: Clyde speakers test review

Howard Popeck ….. In the early 1980s at Subjective Audio Ltd I took a pair of these in part exchange against a pair of Lentek Monitors, transmission line; a Bert Webb design. Those Lenteks, an overlooked ‘classic’ were exceptional and a substantial upgrade in both performance and cost (and size) to the Clyde’s. Those Clyde […]

There’s much to be said for the experiential experience

PS AUDIO / Paul McGowan Many of the products of science we take for granted were discovered by accident: penicillin, Viagra, anesthesia, the microwave oven, chewing gum, brandy, and even silly putty. The key to those discoveries lies in the inventor’s openness to observations unrelated to the original experiment. Take for example, when in 1879, […]

WE’VE EARNED OUR EARS!

PS AUDIO / Paul McGowan As a lifelong photographer, I have, over many decades, developed a practiced eye. What’s that mean? Simply that my eye/brain connections are wired to see through the camera’s viewfinder in such a way that good composition feels natural. (If you’re interested, you can see my photo gallery here). In the same way, we, as […]
