The sixth annual California Audio Show kicks off this Friday, August 14, 10am, at the Westin Hotel in Millbrae. In a lovely location facing the water and within walking distance of several restaurants, audiophiles and the equally curious will enjoy sound in 29 active exhibit rooms, a "Headmasters" room with 7 exhibits, and 5 more exhibits in the hallway...

Ever since 2013, when Alon Wolf's California-based Magico loudspeaker company consolidated its original 5000 sq. ft. Berkeley headquarters and 5000 sq. ft. San Jose warehouse into a single 20,000 ft. facility in Hayward, people have been telling me that I had to experience the company's "incredible" listening room. Ironically, it was only after I had relocated from the Bay Area to Port Townsend, WA, that the opportunity arose to take Alon Wolf up on his long-standing invitation to visit.

Call me a hopeless romantic but I could not get “Penny Lane” out of my head as I sat in the back of a black cab whizzing across a remarkably deserted London early one morning a couple weeks ago. “On the corner is a banker with a motorcar…” I was on a pilgrimage. More like THE pilgrimage. The one every serious fan of twentieth century music needs to make at least once. Out to St. John’s Wood and Abbey Road Studios.

I believe in historical consensus. I believe in hi-fi gear that reveals its quality slowly and holds it value over time, irrespective of technology. I have never bought into the superiority of one technology over another. The art of audio engineering lies in the wisdom and vital energy of the designer's viewpoint within whatever technology he or she has chosen to work with. I call this the designer's qi or chi. Every audio product's most important specification is who created it, followed by the spirit in which it was fostered—and, of course, how it was made and what it is made of. These are the determining factors for long-term audio relevance.

If anyone can be said to be the guru of the transmission line, that would have to be Irving M. "Bud" Fried. He has been promoting the design for years now, first with the made-in-England IMF designs, later with the designs of Fried Products, made right here in the US of A. He has long been convinced of the basic superiority of the design, and still uses it in his top-of-the-line systems. But true transmission lines are invariably big, heavy, hard to build, and, for all of those reasons, expensive. Essentially, they involve a long, convoluted, heavily damped tunnel behind the bass driver which channels the back wave to the outside world. The length and cross-sectional area of the tunnel are of some importance, although the technical basis for the transmission line, as applied to a loudspeaker enclosure, has never been firmly nailed down. Certainly there is no mathematical model for the transmission line as complete as that developed over the past two decades for the sealed or ported box (footnote 1).

But Bud Fried has clung to the transmission line, for all of its complexities. In order to bring at least some of its touted advantages to a lower price point, he had to come up with a variation which would work in a smaller enclosure. That variation was the "line tunnel," which, according to Fried, originated in an early-1970s Ferrograph (a British company specializing in tape recorders) monitor which was later adapted by IMF. Basically it consists of a short (compared with a transmission line) duct from the inside to the outside of the heavily damped enclosure. The duct is designed with approximately the same cross-sectional area as the loudspeaker cone.
