Bookshelf Speaker Reviews

Danish manufacturer Jamo's been making a splash with the spherical speakers we saw back at the 2012 CES, and this week they've announced a pair of 5.0 setups in the appropriately named 360 Series, based around their unique architecture: the S 25 HCS ($649.99), including five of the company's S 25 speakers, and the S 35 HCS ($999.99), which groups four of the larger S 35 units with a C 35 center channel.

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.

The Marimba ($349/pr) is the first speaker ever offered under the Music Hall brand, known for affordable turntables and audiophile electronics. Clearly, the sound was the focus; the Marimba's black ash vinyl wrap finish won't win any design awards. The 1-inch silk-dome tweeter and 5.25-inch, polypropylene-cone woofer are mounted in a rear-ported, 11-inch-high cabinet.
