The conventional wisdom in publishing is that magazines are dependent on scoops—that getting the news out to the readers first is of primary importance. Yes, being timely with what it has to say is important for any publication. But soon after I joined Stereophile in 1986, a series of negative experiences with review samples that were little better than prototypes led me to rethink the need for scoops. As a result, I decided to impose restrictions on what we chose to review; this would allow us to focus the magazine's review resources on products that were out of beta testing and were ready for prime time, and, most important, would be representative of what our readers could audition for themselves at specialty retailers, confident in the knowledge that what they heard would be what we had reviewed.
On the occasion of a recent major birthday, my significant other, Bonnie, gave herself a "mid-life crisis" present—a beautifully restored, bright yellow Porsche 911. She'd spent the previous several weeks wading through reference books to figure out exactly which year and model she wanted, and each night we'd discuss the pros and cons of various models, options, and points in the 911's +30-year evolution. Bonnie explained to me that, throughout its production run, the 911 maintained the same basic design and a consistent set of engineering goals, but was continually updated and refined. In her mind, the 1973 Targa was the one to have, the last and fastest of the lightweight 2.4-liter models.
Bonnie and I decided to avoid the crowds last weekend, and instead settled in at home to watch the recent remake of Great Expectations, with Ethan Hawke and Gwyneth Paltrow. It seemed like a pretty good movie, but before long I found my thoughts drifting to the review I had in progress: my audition and analysis of the Magnepan Magneplanar MG3.6/R. True, Great Expectations is a little slow, and a few explosions or car chases might have better held my attention, but if ever there was an audio product to which the phrase "great expectations" applied, it's the Magnepan 3.6/R.
I must confess to a certain sentimental affection for Magnepan products. An early version of the Tympani did more to rekindle my interest in audio than any other speaker I can think of. In a world which seemed doomed to finding out just how small and dull it could make acoustic suspension boxes, the Magnepans reminded me that speakers could produce a large open soundstage, real dynamics, and musical life.
The Magnep1anar Tympani I that is the subject of this report is already an obsolete model, having been superseded by the Tympanis IA, II, and III that were unveiled at the CE Show in Chicago this past June. Since many of our readers already own Tympani Is, and dealer stocks of them are being sold at a substantial price reduction, the report should still be of interest. We will publish follow-up reports on the newer models as soon as they become available for testing.
If it's rare to go to an audio show and hear most of a company's products set up properly in multiple rooms, it's rarer still to hear those products also sounding terrific in each and every room. Such was my introduction to Marten's loudspeakers at the 2010 Consumer Electronics Show. In each of the systems in which the Swedish company's speakers were set up, and no matter what gear was upstream of them, I heard distinctly neutral, open, musical sound. After having the very same experience with Marten's speakers at the 2011 CES, I concluded that they must know what they're doing, and that their speakers are the real deal. I wanted to review some.
Combine an electrostatic panel to reproduce music's midrange and treble with a moving-coil woofer for the bass foundation. For decades, this has seemed the ideal way of designing a loudspeaker: Each type of drive-unit is used in the frequency region for which its performance is optimized. The resulting hybrid should sing like an angel.
The quest for a full-range electrostatic loudspeaker has occupied many engineers' minds for many years. The problems are manifold: large physical size (which can lead to room placement problems and poor dispersion), the difficulty of achieving high sound pressure levels, the need for a potentially sound-degrading step-up transformer, and the unsuitability for production-line manufacture. Even so, the potential rewards are so great that one can understand why loudspeaker designers keep on attempting the apparently impossible. Epoch-making models do appear at infrequent intervals, keeping the flame burning since the appearance of the original Quad in 1955: Acoustat, Sound Lab, and Beveridge in the US, Stax in Japan, Audiostatic in Holland, Quad, of course, in England, and now MartinLogan.
Most Stereophile readers are aware by now of why the full-range electrostatic should, in theory, be the ideal transducer. (If you aren't aware, see the accompanying sidebar.) Acoustat was the first manufacturer to design a full-range electrostatic that was so indestructible it came with a lifetime warranty. (MartinLogan is now offering a three-year warranty on their speakers, and is considering going to a lifetime warranty). But Acoustat was never able to solve another problem that has plagued all flat-panel speakers: treble beaming.
This lapsed fan of electrostatic speakers finds it curious that, while MartinLogan is the predominant representative of this technology in the US, I had never auditioned an ML design in my home. I've enjoyed many Janszen tweeters, a KLH 9, an AcousTech X, Stax ELS-F81s, and I've dallied with Quad ESL-63s. But as dumb luck would have it, the first MartinLogan speaker to reach me, the new Montage, is a hybrid model.
One of my formative audiophile experiences was the first time I heard electrostatic speakers. I walked into an audio store and heard music played by a live jazz combo. But where were the musicians? I saw none, though I did notice a couple of room-divider panels in the part of the store where the music seemed to be coming from. Eventually, it dawned on me that these must be loudspeakersbut they sounded like no other speakers I'd ever heard, and nothing like the Advents I had at home.
Electrostatic speakers are my passion. Why else have I put up with their high prices, unreliability, low power handling, tendency to arc, high-frequency beaming, limited bass response, and widely fluctuating impedances?
MartinLogan's Gayle Sanders has almost single-handedly raised the electrostatic/dynamic hybrid loudspeaker to a position of prominence in the High End. First, there was the MartinLogan Monolith (reviewed in Vol.8 No.3 and Vol.9 No.3), followed by the much more affordable Sequel (reviewed in Vol.11 No.12, Vol.12 Nos.8, 9, and 12, and Vol.14 No.2). Then came the subject of this review, the Quest, and most recently the diminutive Aerius, reviewed by JA elsewhere in this issue.
Loudspeaker designers are dreamers. Something takes hold of a manthe fact that loudspeaker designers are all men must be significantand he wrestles with recalcitrant wood, arcane drive-units, and sundry coils, capacitors, and cables, to produce something which will be individual in its sound quality yet inherently more true to the original sound. An impossible task. Yet if there were to be an aristocratic subset of those dreamers, it would be those who have taken upon themselves the burden of producing electrostatic loudspeakers. For these farsighted engineers, there is no standing on the shoulders of others, there is no recourse to tried and tested combinations of other manufacturers' drive-units. Every aspect of the design, no matter how apparently insignificant, has to be created afresh from first principles. For a new electrostatic design to produce a sound at all represents a great triumph for its progenitor, let alone having it sound musical. And to produce an electrostatic loudspeaker that is also possessed of great visual beauty is indeed a bonus.
