Stand Loudspeaker Reviews

The tale's been told many times: Back in the early 1970s, the British Broadcasting Corporation needed a small nearfield monitor for use in remote-broadcast trucks. A team led by T. Sommerville and D.E. Shorter, both of the BBC's Research Department, developed the two-way, sealed-box LS3/5, based on a small monitor they'd designed for experiments in acoustic scaling. The speaker showed much promise, but problems with the drive-units—a woofer with a doped Bextrene 5" cone and a 1" Mylar-dome tweeter—led to a detailed redesign, the LS3/5a, carried out by Dudley Harwood, also of the Research Department (and later to found Harbeth), and Maurice E. Whatton and R.W. Mills, of the BBC's Designs Department.

With all the affordable loudspeakers I've written about in recent years, I couldn't remember the last time I reviewed one from the revered British firm Bowers & Wilkins. When I searched www.stereophile.com, I learned that the last time a B&W speaker had graced my listening room's carpet was more than seven years ago: the DM603 S3, reviewed in the August 2005 issue. I thought it was time to revisit the brand, and as the DM603 S3 was a floorstanding speaker, this time a bookshelf model seemed in order.

Recently, I thought about all the audio shows I've attended over the last 27 years, looking for any pattern that all of them might have shared. I came up with a handful of audio manufacturers that have earned at shows a reputation for getting, year after year, consistently good sound—rooms in which I could reliably depend on being able to chill out and enjoy music in good, involving sound. Those companies include Audio Research, Music Hall (distributor of Creek and Epos), Vandersteen Audio—and Definitive Technology. Since their founding, in 1990, Maryland-based DefTech has been a major presence at shows, displaying an increasingly wide range of high-value speakers for two-channel and surround-sound systems. But I'd never reviewed one of their models. I thought it was about time.

When a reviewer specializes in seeking out innovation and value in affordable loudspeakers, certain manufacturers warrant revisiting again and again—companies that consistently deliver high-value products, but also steadily revamp their lines to trickle down design innovations to ever more affordable models.

The first loudspeaker I heard from the Canadian company PSB was the Stratus, an affordably priced ($1400/pair), two-way tower with a soft-dome tweeter and an 8" woofer. The Stratus had benefited from designer Paul Barton's being able to use the anechoic chamber at the Canadian government's National Research Center, in Ottawa. The Stratus was reviewed for Stereophile by J. Gordon Holt in our May 1988 issue; he described the speaker as "eminently listenable," though Gordon also felt that it was "a little lacking in guts and liveliness." I had sat in on some of his listening sessions and had been impressed by what I heard.

Back at home, I'd recently set up Polk Audio's RTi A3 loudspeakers ($399.95/pair), which, at 14.75" H by 8.58" W x 14" D, are by far the largest bookshelf models I've had in my listening room. Right out of the box, the RTi A3 impressed me with its fit and finish. In Polk's Damped Asymmetrical Hex Laminate Isolation (DAHLI) cabinet design, five layers of MDF are glued together to form a damping system, then topped by a real-wood veneer of black ash or, in the case of my review samples, an impeccable cherry. The gracefully curved cabinet narrows in width from 8.58" at the front to about 5" at the rear, and is said to create a stronger, more rigid, more acoustically inert enclosure. (Knocking on the speaker's side panels resulted in a hollow resonance.)

I thought I'd review the procedure I typically use to seek out affordable speakers for review as, in the case of the Denmark-designed DALI Zensor, made in the company's facility in China, there was a twist at the end.

In preparing to review affordable loudspeakers, I typically put together a list of potential candidates I've discovered at audio shows, or that have been recommended to me by other Stereophile writers. I add to that list products I've learned about from press promotions, usually from companies whose products have impressed me in the past. I boil this down to a short list, then run it by Stephen Mejias to make sure I'm not tripping over The Kid's own quest for budget sonic nirvana.
