Bookshelf Speaker Reviews

It seemed that audio companies had surrendered the home-theater-in-a-box concept to the TV manufacturers.

When the economy tanked in 2007, a funny thing happened in high-end audio: Many manufacturers prospered by creating even higher-priced products. As a speaker reviewer, I lack the economics chops to explain this turn of events, but I can tell you it has spawned some fascinating audio gear.

Take, for example, Steinway Lyngdorf ’s S-Series, built to be the Bugatti Veyron of compact home theater systems.

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.

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.

Everybody loves small speakers, and why not? Smaller is — often — easier to afford, easier to schlep home, easier to place, and easier to live with. Smaller also has certain acoustical advantages in achieving smooth response and in yielding the broad, even spread of sound that favors good imaging and an open, believable tone color.

But how small is too small? Some say there’s no limit, and at least one manufacturer (Bose) has had success with subwoofer/satellite designs whose sats are smaller than a pepper mill, let alone a breadbox. But as the front satellites of a speaker system become smaller, their ability to reproduce bass low enough to bridge effectively with the practical upper limits of a single subwoofer, at around 150 Hz (and ideally lower), becomes questionable.

Klipsch thinks it has found the sweet spot with its HD Theater 600 system

Hsu Research ranks high on home theater enthusiasts' "most favored brands" list, largely because of its high-performance, low-priced subwoofers. Indeed, the HB-1 MK2 ($318/pr) seems to be designed primarily as a home theater bruiser: At 15.4 inches high, it's the largest speaker in this roundup, and its 6.5-inch, polypropylene-cone woofer gives it more bass real estate than any but the Axiom M3v3.

Usually, a sub-$400/pair minispeaker is part of a manufacturer's entry-level line, but the RB-41 II ($299/pr) is part of Klipsch's Reference line. It uses the horn-loaded tweeter that has been a Klipsch hallmark since the 1940s - in this case, a 1-inch titanium-dome model - and a ceramic/metallic-cone 4-inch woofer in a rear-ported enclosure.
