Stand Loudspeaker Reviews

This is a speaker we've been fairly intimate with over quite a period of time. Designed by John Bau, the SC-50i started out three years ago as an inexpensive speaker system ($330/pair) not sold through dealers.

One of the factors allowing it to cost so little was the clever adaptation of cardboard tubes, normally used as forms for pouring concrete pillars, for use as speaker enclosures. They have a number of advantages, other than low cost: their circular form helps eliminate resonance of the back wave within the enclosure; the material is rigid because of its shape, and is non-resonant due to its construction.

The BBC-designed LS3/5a monitor loudspeaker has been in continuous BBC-licensed production in various forms since 1975. During those 45 years, its popularity has never abated. I bought my first pair of LS3/5a's as a Badger kit from an ad in the back of Speaker Builder magazine.

In the September 1988 issue of Stereophile, I wrote a rave review about the first speaker, the AE1, from what was to me a totally unknown English company, Acoustic Energy. Though tiny, and possessing an intrinsically limited low-frequency response, the $1500/pair AE1 was one of the most musical loudspeakers I have ever used, throwing a deep, beautifully defined soundstage, and possessed of a clean treble and a sweet, if rather forward-balanced, midband.

KEF's LS50 loudspeaker was introduced in 2012 to celebrate the English manufacturer's 50th anniversary. Usually, anniversary models are large, floorstanding "statement" designs with a price to match, but the LS50 was a minimonitor, priced at $1500/pair. I reviewed the Anniversary Edition LS50 in December 2012 (footnote 1), writing that it was rare to find a loudspeaker that offers this combination of clarity and neutrality and concluding that within its limits of dynamic range and bass extension, the KEF LS50 "will provide Class A sound for those with small rooms."

Three products are the subjects of lengthy followup reviews in the December issue of Stereophile: MBL's Noble Line N31 CD player-D/A processor, the GoldenEar BRX loudspeaker, and Alta Audio's Alyssa loudspeaker.

It was a "Wow!" audio moment I'll never forget. It happened just after Ladies Who Lunch, our regular Friday afternoon lunch-n-chat for audio poobahs at the Grand Sichuan restaurant in Chelsea. It was dark at 4 o'clock, and the first snow of winter looked enchanting under the 24th Street streetlamps. Audiophiliac Steve Guttenberg and I were accompanying our turntable setter–upper friend Michael Trei to Bob Visintainer's Rhapsody Music and Cinema, where Trei was scheduled to install a Lyra Etna SL cartridge on a TechDAS Air Force III turntable. I tagged along to chatter with Bob and listen with Steve to Alta Audio's tall, open-baffle Titanium Hestia loudspeakers. Rumor had it that this was a happening system.
