OMA Ironic

Cast from the same hypoeutectic iron used to create silicon chips, the 400-pound behemoth filters sound through a cluster of studio-grade quadratic diffusers.

$95,000 per pair, oswaldsmillaudio.com.

Devialet Phantom

The brainchild of 40 engineers and scientists, the single-unit, room-filling Phantom receives music via WiFi and uses revolutionary new acoustic architecture, including what it calls “Heart Bass Implosion,” to generate the kind of dense, distortion-free audio you’d expect from speakers 20 times the size.

$1,990, devialet.com.

OMA Mini

This two-way speaker’s compact profile—just 14" x 14" x 57"—can be deceptive: the highly efficient setup produces rich, powerful playback with its proprietary conical horn and neodymium compression driver.

$28,750 per pair, oswaldsmillaudio.com

Bang & Olufsen Beolit 15

The mobile speaker’s omnidirectional sound field is enhanced by elements typically found in much larger, multi-unit systems—a full-range driver, three tweeters for heightened clarity, large bass radiators and separate amplifiers.
