Powerful, massive, and expensive, Revel's Ultima Rhythm2 subwoofer ($10,000) swept me off my feet when I first saw it in Harman International's suite at the 2013 Consumer Electronics Show. It outsizes, by 49 lbs and 2.6 cubic feet, Revel's previous flagship model, the Ultima Sub30, which I reviewed in the November 2004 issue. Its specs read like no other sub's: 196 lbs; 18" cast-frame woofer; dual 4" voice-coils; 4kW peak power from twin internal amplifiers that generate 1kW RMS; 115dB peak acoustic output; a fully configurable, high-resolution, 10-band parametric equalizer (PEQ); an internal crossover with high- and low-pass outputs; and PC-based setup via USB. The Rhythm2's patent-pending design is said to let just enough air move in and out of the cabinet to prevent any distortion-inducing pressure due to heating of the voice-coils. And its veneer, shape, beveled top edges, and bottom plinth exude the quality found in Revel's top-of-the-line floorstanding speaker, the Ultima Salon2, with which I was familiar.

Lamm Audio used two ML3 Signature amplifiers ($139,490) and two ML2.2 amplifiers ($37,290) to power a pair of Verity Audio Lohengrin IIS loudspeakers ($120,000) in one of the Venetian's largest exhibit rooms.

Abbey Masciarotte, Tannoy's representative at CES 2015, showed me the company's floorstanding Canterbury loudspeaker. The Canterbury has a striking retro look and uses a dual-concentric 15" drive unit that mounts a high-frequency compression driver inside the throat of a 15" woofer.

Wilson Audio’s Peter McGrath and John Giolas walked me through the design of the new $15,000/pair Sabrina. The loudspeaker has same general form factor and is slightly taller than their original WATT-Puppy, which was also a $15,000/pair speaker when it was first produced more than 20 years ago.
