There was once an Englishman named H.A. Hartley, who was a contemporary of H.G. Baerwald, P.G. Voigt, P.K. Turner, and other men whose first two names are lost to us. Hartley was a capable designer and audio theorist, not to mention a gifted lecturer and writer—his literary achievements include a book on astrology (footnote 1), of all things—and he's often credited with coining the expression high fidelity. Most important of all, in 1928 H.A. Hartley teamed up with the aforementioned P.K. Turner to create an audio manufacturing company known as Hartley Products, Ltd. The Hartley company made electronics and loudspeakers, the latter of which included full-range coaxial drivers using energized field coils and, later on, quite powerful permanent magnets—just like their countrymen at Lowther Loudspeakers, Ltd.
The Hartleys I wrote about last month may be the loudspeaker drivers that time forgot, but the venerable Lowthers of Sidcup, England, reign supreme as the horseshoe crabs of the loudspeaker world: strange, ungainly things that have scarcely changed since the days when Franz Schmidt and Robert Johnson walked the earth. Literally.
We were having trouble with the power in our home—the wall current, I mean, not the dynamics of our marriage—so I called the local utility. While the technician was here, he let me watch what he was doing. I had a chance to look inside our meter box, which is the junction between the utility's power lines and the circuit-breaker box in the cellar.
Not only is it possible for a thinking person to now and then drastically change his point of view, if for no other reason than the sake of change—if one wishes to prevent self-seriousness and various other forms of mental decay, it's probably an outright must. So it was that I recently began to wonder if everything I know about record players might be wrong.
Going from being an audio hobbyist to a professional reviewer is like passing kidney stones in an emergency room staffed with Playboy bunnies: Not only can you not have what you want, but you don't even want it anymore. In fact, you begin to consciously associate desire with a blinding pain in your crotch.
In his June, 2006 "Listening" column, Art Dudley discussed the original Quad ESL loudspeaker, and started to describe the task of refurbishing a 47-year-old pair of them; this month, Art fries a pair of transformers and nearly ruins his new wall oven—but finishes the job nevertheless. Please remember that sharp tools, solder flux fumes, and the high voltages typically present inside an electrostatic loudspeaker can sicken or kill you if you don't proceed with caution, and neither Stereophile nor its parent company, Primedia, can be responsible for the suffering or loss that may befall readers who follow Art's advice. Thank you.
