Floor Loudspeaker Reviews

I am puzzled. No, really. I know you find it hard to believe that we sacerdotes of the golden-eared persuasion could ever be perplexed, but I have been pondering the imponderables of ports. Ever since the classic work of Richard Small and Neville Thiele in the early '70s showed how the low-frequency response of any box loudspeaker can be modeled as an electrical high-pass filter of some kind, with the relevant equations and data made available to all, there would seem to be very little reason why all loudspeakers with the same extension should not sound alike (or at least very similar) below 100Hz. Yet after reviewing 20 dynamic loudspeakers (and using 24) in the same room over the last seven months, I am led to the conclusion that speakers vary as much in the quality of their mid-to-upper bass as they do in any other region. A few are dry, more are exaggerated in this region; some are detailed and "fast," most are blurred, with the upper bass "slow" (by which I mean that the weight of bass tone seems to lag behind the leading edges of the sound).

The made-in-Switzerland Stenheim Alumine Three floorstanding loudspeaker sells for $32,900/pair. It is not only the most expensive component I've reviewed for Stereophile; it costs more than 10 times (!) as much as my $3000/pair reference Falcon Acoustics Gold Badge LS3/5a speaker. So naturally I wondered: Will it sound 10 times better? And if it does sound 10 times better, what might the nature of the improvements be?

Stereophile has favorably reviewed three loudspeakers from Swiss manufacturer Stenheim. Art Dudley reviewed the Alumine standmount in April 2012 and the Alumine Five floorstander in March 2018. More recently, Herb Reichert reviewed Stenheim's three-and-a-half-way Alumine Three tower in October 2021. My assignment for this month's issue was to review the company's Alumine Two. Five floorstander, which, at $23,500/pair, fits neatly between the Alumine Two ($13,500/pair) and Three ($36,500/pair).

As a privileged reviewer-type person, I was sent the souped-up, all-rosewood, bi-wirable version that sells for $2905/pair. They're quite handsome and very solidly built, weighing in at a respectable 50 lbs each. At $2275–$2905/pair, the Baton is Swans' most affordable speaker, and reportedly employs many of the technical refinements of their larger, more costly models.

The Baton uses the tried-and-true two-way dynamic design, with a 7" coated-paper woofer and a 1" fabric-dome tweeter. The tweeter comes with a little Marigo dot stuck to its center to shape its response. It's not a physically easy task for a woofer to reproduce (well) all the frequencies from about 60Hz up to about 2 or 3kHz. One that succeeds is a nice find, though, because the sound has a nice coherence to it when most of the music is coming from the same driver. But don't take my word for it—just look how many zillions of two-way speakers there are out there.

Denmark has probably contributed more to loudspeaker technology than any other country in the world. Vifa, Dynaudio, ScanSpeak, and Peerless drivers—used in a huge variety of speakers—are all Danish. Products from companies such as JBL, Spendor, Linn, B&W, Celestion, KEF, Audio Physic, ProAc, and others are partially or wholly made in the little Scandinavian nation.

System Audio originated in 1984, when guitarist and electronics technician Ole Witthoft grew dissatisfied with the lack of realism he heard from most home audio systems and figured he could do better. He built some speakers for himself and for a few friends, with encouraging results. It's a familiar story: we all know competent hobbyist speaker builders. A few of them gain a bit of local notoriety, but most never venture further than making a few units for friends and relatives.

But Witthoft's reputation grew rapidly, and so did his business. Fourteen years later, his little startup has become a serious player in the loudspeaker market, with annual production in excess of 18,000 units.

I jumped at the chance to review T+A's $47,900/pair Solitaire S 530 loudspeaker for a few reasons. First, because T+A is a well-established company with an approach I like and respect: They make hi-fi equipment of the highest quality but with prices that, though substantial, are in line with their technology and execution. Their stuff is very handsome with impressive industrial design, but T+A doesn't do audio jewelry. What's more, though T+A is aggressive in R&D—their "Company" webpage says, "Actually, we're scientists ..."—but they are selective in the use of new technology. The third reason I was interested in reviewing a product from T+A is that their prices and technical level place them in a market segment I know well.

What I didn't know until recently is that T+A makes loudspeakers, and they're quite different from the loudspeakers other companies make. I only learned this when I started hearing about the S 530 and its larger sibling, the S 540, from friends—friends whose ears I trust.

I had been anticipating getting to audition a pair of TAD loudspeakers in my system since the introduction of the original TAD Model-1, in 2003. It was designed by Andrew Jones, who had recently assumed the mantle of chief designer at Technical Audio Devices Laboratories (TAD), at that time a subsidiary of Pioneer. Although TAD dates back to the mid-1970s, its research and development efforts had been focused on the professional sound market, something that continues. Jones came from a long line of speaker innovators at KEF and was assigned the goal of developing state-of-the-art speakers for the domestic market.
