Subwoofer Reviews

We have inherited an infinitely vast library of recorded musical art, the majority of which is well-recorded but has yet to be fully and completely reproduced. Countless times, I've played an album and thought, am I the first person ever to hear this recording sound this clear and microscopically detailed? Audiophiles understand that in order to be fully enjoyed, great recordings need the finest possible audio reproduction. Reciprocally, the finest audio systems are best enjoyed when playing great recordings. It's a horse and carriage thing.

SVS's recently introduced SB-3000 is a compact powered subwoofer that's $600 cheaper, a few cubic inches smaller, and 37lb lighter than the model it replaces, the SVS SB13-Ultra. Its amplifier is less powerful (800W vs 1000W), but its rated frequency response extends lower: a stygian 18Hz, compared to the SB13-Ultra's merely stentorian 20Hz.

In the late 1980s, when I began reviewing high-end subwoofers, they were big and heavy, difficult to move or find space for in a room. Their controls were always on an inconveniently positioned rear panel, and there were no built-in automatic room-optimization options or parametric equalizers. Velodyne's 105-lb, downfiring ULD-18 ($2570), ca 1989, was typical: Two people were needed to unpack and move it; it was powered by an outboard 400W amplifier, connected inconveniently with a speaker cable and an RCA-terminated interconnect for its servo control; and its controls were on the bottom of the cabinet. Changing its crossover frequency involved soldering new resistors onto a printed circuit board inside the amp.

It was all so familiar. In "Music in the Round" in the January 2016 issue, Kal Rubinson praised JL Audio's latest subwoofer, the Fathom f113v2. He raved about its amplifier's higher power over the original f113, its beefier 13" woofer, its improved, 18-band Digital Automatic Room Optimization (DARO), and its significantly improved deep-bass response in-room.

It was familiar because the same thing had happened when Kal reviewed the original Fathom f113 in his May 2007 column. As he would again nine years later, he'd extolled the sub's high power, small size, built-in single-band Automatic Room Optimization (ARO) software, and "remarkably powerful and clean" deep bass. Those were also my reactions to the Fathom f113.

Ten years ago, our family was joined by my son-in-law, who was raised in Dublin, and spent his university years in London. I was editing this review during a recent visit with our daughter and grandchildren, and Justin became interested in the fact that I was reviewing a subwoofer made by Tannoy. He reminded me that, in the UK and Ireland, Tannoy had long been a generic term for public-address systems, just as Hoover had come to describe any vacuum cleaner, regardless of manufacturer. Although Justin admitted that this usage was probably "old school," he teased me that I was reviewing a PA speaker for an audiophile magazine!

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.

I like big bass, but I cannot lie
Tubby thumpers need not apply
And when a speaker drops in with itty-bitty bass
It puts a frown upon my face
I get bummed . . .
—Sir BassaLot, first audiophile rapper, 1992

Some folks put a pair of bookshelf speakers on stands in their room and are happy as clams. I imagine that they imagine the missing bass and never give it another thought. Not me, and perhaps not you. Some of us want to hear it and feel it, just as we would real instruments. We want sex in the room.
