Floor Loudspeaker Reviews

TDL is part of ELAC, one of the most successful OEM drive-unit manufacturers in the UK, particularly renowned for the 1" aluminum-dome tweeter that they make for Monitor Audio, Acoustic Energy, and British Fidelity. Perhaps of even more interest to readers of Stereophile is that the TDL system designer is one John Wright, who designed the classic series of IMF loudspeakers and who also was one of the leading equipment reviewers in the UK back in the 1960s. (For a while John was also a contributor to this magazine, his comprehensive reviews of tonearms appearing in Vol.2 Nos.10 & 12.)

John Ötvös, the father of Waveform Research Inc. and The Waveform Loudspeaker, hesitates not at inviting ultracritical examination: "The Waveform is the most accurate, the best, forward-firing loudspeaker in the world." Period. Reviewers, of course, welcome such statements, and I'll be examining that one, but I'll also try to answer the inherent reviewing question of whether the Waveform is a good place for you to park $9800 on your way to "the highest of high-end sound" (that was our slogan for the first Santa Monica High End Hi-Fi Show).

Loudspeaker designers are dreamers. Something takes hold of a man—the fact that loudspeaker designers are all men must be significant—and 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.

When it comes to loudspeaker drivers, Dynaudio has earned an enviable reputation for quality and reliability. To use an automotive analogy, they are the Mercedes Benz of the driver universe. If you're a speaker builder, the odds are that you have already experimented with these drivers. And even if you're not a speaker builder, it's quite possible that your speakers use Dynaudio drivers. After all, some of the finest speaker systems in the world do. A case in point is the Duntech Sovereign, which single-handedly embodies almost the entire Dynaudio catalog.

Mirage /ma-'räzh/ n [F, fr mirer to look at. fr. L mirari] 1: an optical effect that is sometimes seen at sea, in the desert, or over a hot pavement, that may have the appearance of a pool of water or a mirror... 2: something illusory and unattainable, like a mirage.

One of the joys of reviewing loudspeakers is that there are always intriguing aspects of any particular design. The problems involved in producing a speaker that has an even tonal balance, well-controlled directivity, good bass extension, and a smooth integration of the outputs from often widely disparate drive-units have what appears to be an infinite number of solutions. The result is often a speaker so different from the norm that it just cries out to be auditioned.

Such was the case with the Delaware Acoustics DELAC S10, which costs $629/pair. Only sold factory-direct, this would therefore have been low on Stereophile's priority list for review if it weren't for two things: first, the fact that the S10 was designed by one Ralph Gonzalez, a name that should be familiar to readers of Speaker Builder magazine for having written a very useful speaker design and analysis program; second, as implied in the first paragraph, the S10 is one of the weirdest speakers I have ever laid ears on.

Thiel Audio, headed up by Jim Thiel (President and chief designer) and Kathy Gornik (Marketing Director), sets itself apart from other speaker manufacturers not only by making what I feel to be almost uniformly excellent products, but also by serving as a kind of hallmark for the good dealer: Although not all good dealers sell Thiel, just about every Thiel dealer is a good one. This comes about because, in spite of just about uniformly positive reviews and excellent customer relations, Thiel (primarily in the person of Ms. Gornik) has insisted on limited distribution through retailers they know will give their product a good demonstration. There are a few other such companies performing this hallmark function, though only Mark Levinson Audio Systems readily comes to mind. Most other successful companies prefer as wide a geographical distribution as possible, in spite of the occasional necessary compromises in dealer quality.
