Looking for a great sounding set of home theater speakers but on a tight budget? Read on and find out why Pioneer's newest speakers might be just what the doctor ordered and learn how gifted designer Andrew Jones met the challenge of building a high-performance speaker ensemble that can be had for only $500. Even he can't believe it.

Like so many British (and, for that matter, American) ür-audio brands, KEF — originally Kent Engineering & Foundry — had its roots in the post- WWII technology boom. In KEF’s case, it grew inside a Quonset hut on the grounds of the aforementioned foundry. A half-century down the road the Kentish maker is still there (in Kent, not in the metal shed!), still focused on its core competency (loudspeakers), and still producing wholly excellent designs.

As athletes such as Michael Vick, Kobe Bryant, and the whole New Orleans Saints defense have learned the hard way, even when you’re the best, it helps to be friendly. Big surround sound systems aren’t friendly to your décor or your pocketbook. Fortunately, in the last 2 years, we’ve seen major speaker companies put serious effort into designing compact 5.1 systems that deliver no-compromise performance. The Mini Theatre line from Bowers & Wilkins is the latest to make its way through my listening room.

When I’m looking for speakers to review, I gravitate toward two types: ones that have the potential to sound great, and ones with weird designs. The former offer the potential for hours of joyous listening. The latter offer the potential for either a previously unimagined sonic nirvana or an audio train wreck, both of which are fun to write about.

Definitive Technology’s $899-per-pair StudioMonitor SM65 fits both descriptions.

Kent, in the south of England, was best known for hop farming when Raymond Cooke left Wharfedale and founded KEF in 1961. The company was named after the industrial site on which it was founded: Kent Engineering & Foundry. KEF’s numerous distinguished alumni include Laurie Fincham, who now develops next-generation audio technologies for THX, and Andrew Jones, who designs world-beating loudspeakers at a variety of price points for Pioneer and TAD. KEF has earned a reputation for making both great speaker systems and great speaker drivers, some of which were instrumental in the legendary BBC-designed LS3/5A, which KEF and other manufacturers have marketed in various forms. Roving through a New York cocktail party celebrating KEF’s 50th anniversary last year, hobnobbing with the audio elite, I found that the drive units inspired as much nostalgia as the speakers in which they were used. (To read about KEF’s history in more detail—and in a handsome coffee-table book, no less—see KEF: 50 Years of Innovation in Sound by Ken Kessler and Dr. Andrew Watson.)

Spherical loudspeakers are perhaps too easily dismissed: “Oh look, it’s round. Cute gimmick. Next…” That box speakers are easy to build certainly doesn’t guarantee sound quality. In fact, designers of quality speakers are constantly rebelling against the limitations of rectangular enclosures. To curb cabinet resonance, designers build bracing into the box and stuff the interior with damping material. They curve the sides to stop standing waves from developing between parallel walls. But rather than tweak boxes, some do away with them altogether. So if you think the spherical steel shells of Orb Audio’s People’s Choice satellite speakers are mere gimmicks, think again.

If there’s any speaker spec that’s routinely bogus, it’s bass response. You see a lot of little speakers rated to deliver bass below 40 Hz, but that measurement is almost always taken at -10 dB, instead of the industry standard of -3 dB. Even if the little speaker does hit, say, 36 Hz at some level, it almost certainly can’t deliver any usable volume at that frequency.

There are ways, though, to get legit sub-40 Hz response from a little speaker. One is H-PAS, or Hybrid Pressure Acceleration System, invented by Solus-Clements and now used and licensed by Atlantic Technology.
