PSB Stratus loudspeaker
PSB is a small, Toronto-based manufacturer that has been collaborating with Canada's National Research Council to try and take some of the guesswork, some would say magic, out of loudspeaker design.
The NRC, financed by the Canadian government, does basic research in many technological areas and makes its findings available to any firm wishing to use them. (Most other countries provide or encourage this kind of government/business cooperation. It is against the law in the US, to our great disadvantage.) The NRC's audio division, headed by physicist Dr. Floyd E. Toole, has devoted the last several years to the rather formidable task of defining, and assigning numbers to, the various aspects of loudspeaker performance that affect listeners' subjective assessments of their sound.

"Something's wrong. It sounds confused."
PSB Synchrony T600 loudspeaker
Exactly five years ago as I write these words, I reviewed an elegant-looking and elegant-sounding tower loudspeaker from Canadian manufacturer PSB: the Imagine T3. Priced at $7498/pair before it was discontinued, the T3 combined three woofers, each housed in its own vented subenclosure, with a 5.25" midrange unit mounted above a 1" tweeter.
Q Acoustics 5040 loudspeaker
When I reviewed the Concept 50 loudspeaker from the UK's Q Acoustics in August 2022, I concluded that the Concept 50 lowers the sweet price spot for affordable tower speakers to $3000/pair. Now I have another pair of Q Acoustics loudspeakers in the house for review. Like the earlier speaker, the 5040 is a slim, elegant-looking tower with a vertical D'Appolito drive-unit array comprising a 0.9" fabric-dome tweeter positioned between the two 5" plastic-cone woofers. But the price is half that of the Concept 50: $1499/pair. Will this be a new sweet spot? We shall see.
Q Acoustics Concept 50 loudspeaker
Given how crowded the loudspeaker manufacturing space has always been, I am always surprised when a new brand not only springs into being but does so with new speakers that sound and measure well. Take the UK's Q Acoustics, for example. The company didn't exist before 2006 and didn't have a presence in the US until 2018.
Q Acoustics Concept 500 loudspeaker
Q Acoustics was founded in the UK in 2006, but has appeared on the radar of US buyers only in the last few years. Until recently, Q has aimed its efforts at the budget sector, earning enthusiastic reviews and commercial success.
But during that time the company also been quietly working on a product considerably more upscale, though still affordable in a marketplace now glutted with products at if-you-have-to-ask prices. The result is the Concept 500 ($5999.99/pair), first seen in the UK in 2017 and recently made available here. But you won't find it at your local audio shop (if you still have one); in the US it's currently sold only online, through Q Acoustics' US website, with a 30-day, money-back guarantee that includes shipping costsboth ways.
Quad ESL loudspeaker
High fidelity took a giant step forward in 1956 with Peter Walker's introduction of the Quad ESL. Walker's research efforts had been motivated by his firm belief in the superiority of the electrostatic dipole over the box loudspeaker, but actually to take the economic plunge and market such a speaker was surely an act of bravery. After all, those were the pre-stereo, pre-audiophile days of the mid '50s, and the public's tastes and expectations were relatively unsophisticated. The average front end was abominable by today's standards, so that making definitive assessments of loudspeaker quality was a difficult task at best.

If Stereophile gave an award for Loudspeaker We've Most Frequently Reviewed, the hands-down winner would have to be the Quad ESL. The list of past and present Stereophile contributors who've written about the ESL's various incarnations includes John Atkinson, Martin Colloms, Anthony H. Cordesman, Art Dudley, Larry Greenhill, J. Gordon Holt, Ken Kessler, Dick Olsher, Herb Reichert, William Sommerwerck, Steven Stone, and Sam Tellig. The ESL-63 was John Atkinson's personal "Editor's Choice" in 1992, and the ESL-989, a successor to the ESL-63, was Stereophile's 2003 Loudspeaker of the Year and Product of the Year.
Quad ESL-63 loudspeaker
Warning to Purists: Despite certain qualities about the ESL-63 speakers which you will probably like, Quad equipment is not designed primarily for audiophiles, but for serious-music (call that "classical") listeners who play records more for musical enjoyment than for the sound. Quad's loudspeakers do not reproduce very deep bass and will not play at aurally traumatizing volume levels, and Quad's preamplifier is compromised through the addition of tone controls and filters, all for the purpose of making old, mediocre, and/or worn recordings sound as listenable as possible.
Quad ESL-989 electrostatic loudspeaker
I first heard Eugene Gigout's pipe-organ masterpiece, the Grand Chorus in Dialogue, in the Smetana Concert Hall of Prague's Municipal House (Obecnim Dome) on a Saturday evening before the 2002 flood. I recall seeing the delicate, youthful Michele Hradecka sway from side to side to reach the pedals. In response, a massive wall of deep organ chords shook the hall, the magical acoustic blending the delicate, extended highs with the thunderous bass. But this memory mixed the music with the beauty of Prague's soaring church spires, brilliant red terracotta roofs, and lavish palaces.
