Stand Loudspeaker Reviews

The most exciting development in audio today isn't multichannel surround, single-ended triodes, or $10,000 phono cartridges. It's "trickle down." I get buzzed when an audio designer known for cutting-edge multikilobuck designs claims to have a product that can produce 80% of the sonic realism of his flagship design at 50% of the cost. I get even more excited when he does it again—that is, produces a product that produces 64% of his flagship's performance at 25% of the cost. Designers who have successfully trickled-down their flagship technologies abound in all quarters of audiophilia, from electronics (eg, Audio Research, Conrad-Johnson) to speakers (Alón, ProAc) to cables (MIT).

I approached this loudspeaker much as some of today's political candidates might approach sex: as a means of reproduction, not pleasure.

I brought it on myself. I asked to review Joseph Audio's stand-mounted, two-way Pulsar because I felt an obligation to step down from the rarified air of some of the absurdly priced gear I've been reviewing lately and sample something more "affordable." The Pulsar costs $7000/pair.

Jeff Joseph always causes a stir at Stereophile's annual Home Entertainment Shows. No matter which speakers he exhibits, he invariably gets wonderful sound in his room. He's fooled more than one Stereophile writer who thought he was listening to Joseph's flagship Pearls when, behind a curtain, it was actually two of his in-wall models that were playing. And his competitors seem to envy his hi-fi show sound more each year.

The tale's been told many times: Back in the early 1970s, the British Broadcasting Corporation needed a small nearfield monitor for use in remote-broadcast trucks. A team led by T. Sommerville and D.E. Shorter, both of the BBC's Research Department, developed the two-way, sealed-box LS3/5, based on a small monitor they'd designed for experiments in acoustic scaling. The speaker showed much promise, but problems with the drive-units—a woofer with a doped Bextrene 5" cone and a 1" Mylar-dome tweeter—led to a detailed redesign, the LS3/5a, carried out by Dudley Harwood, also of the Research Department (and later to found Harbeth), and Maurice E. Whatton and R.W. Mills, of the BBC's Designs Department.

I keep getting older. By the time you read this, I will be genuinely old. When I was genuinely young, I bellyached, "Wires are the worst part of hi-fi—there's gotta be a way to get rid of them." I first made that statement when audio electronics and loudspeakers both still nestled inconspicuously in proper bookcases. Back then, people sitting on the sofa weren't forced to stare at diverse audio boxes and ungainly wires.

Stereophile is, in one sense, like a family—us younguns have to make do sometimes because the house is straining at the seams. When I first arrived in Santa Fe, for instance, I was told not to come to the office for a few days—the good news, John Atkinson informed me, was that I had a desk; the bad news was that nobody had a clue where to put it. The dilemma was solved in Solomon-like fashion by shoehorning my desk into the "listening room," which was already serving double-duty as audition space and speaker-measurement lab. If manufacturers visited, we'd sweep up all the acoustic damping from the floor and stash it in JA's office; and if JA needed to take measurements, I would be asked to work at home. It was a manifestly fair solution: inconvenient for everyone involved.

At the risk of offending nearly every designer and manufacturer of loudspeakers, I think we have not seen anything really new in a long time. Casting a gimlet eye at Stereophile's "Recommended Components" reveals some electrostatic and planar-magnetic models, a few horns, and lots and lots of cones and domes in boxes. Those cones and domes have voice-coils inductively driven by permanent magnets, and overwhelmingly use passive crossovers. Innovation in speakers mostly takes the form of advancements in materials science and, to a much lesser degree, cabinet shape. All helpful, but not revolutionary.
