Audio Physic Rhea powered subwoofer
"You can't get deep bass in your room," a reviewer from another magazine who'd never visited my room insisted recently on the phone. "Do you know how long a 20Hz bass wave is? It's 40 feet long, and your room is tiny."
Bowers & Wilkins DB1 subwoofer
Although many high-end audio products are described as revolutionary and as breakthroughs in design when new, most audiophile components now on the market have not changed our way of relating to such products in the way the iPad has done. Once in a while, a new audio product does move in that direction by enabling the audiophile to do install a product and optimize its performance in a different way.
Genelec HTS4B subwoofer
Home theater has dramatically influenced the design of aftermarket subwoofers. Multichannel processors automatically provide a properly filtered low-frequency signal to drive a subwoofer, relieving the need for the sub to be shipped with a passive crossover network or an active electronic crossover. When Genelec offered one of their subwoofers for review, I decided it was important to try to evaluate such a product, even if it meant I'd have to scramble around to find a quality external electronic crossover.
Gradient SW-57 subwoofer
There are two kinds of audiophiles: those who own original Quad ESL speakers and those who don't (footnote 1). This review is for the former, although the latter may find it of some interest. The Gradient SW-57 subwoofer attempts to do for the original Quad (footnote 2) what Gradient's SW-63 (footnote 3) does for the Quad ESL-63: supply the bottom octave while relieving the ESLs of the strain of reproducing low bass.
James Loudspeaker EMB-1200 subwoofer
Harry Partch (1901-1974), composer and inventor of musical instruments, delighted in generating deep bass. Finding most standard orchestral instruments wanting in that department, he built the huge Marimba Eroica, which he described on his A Glimpse into the World of Harry Partch: 27 Unique Instruments (LP, Columbia MS-20576):
JL Audio Fathom f110v2 powered subwoofer
Some contentious issues will not be resolved in my lifetime: vinyl vs digital, tubes vs solid state, subjective vs objective, streaming vs physical media.
Also, subwoofers vs no subwoofers in a stereo music system.
JL Audio Fathom f113 powered subwoofer
Carl Kennedy, director of JL Audio's Home and Professional Sales division, leaned forward and quietly asked, "Would you like to review our Fathom f113 subwoofer?"
JL Audio Fathom f212 powered subwoofer
It's been over two years since I reviewedhttp://www.stereophile.com/subwoofers/907jl">reviewed; a pair of JL Audio's Fathom f113 subwoofers. Kalman">http://www.stereophile.com/musicintheround/1106mitr">Kalman Rubinson and I both gave the f113 top marks for delivering clean, powerful bass in a wide variety of full-range systems. At the end of the review period, JL Audio's Carl Kennedy told me that they wouldn't send me another subwoofer for review until they had developed one that outperformed the Fathom f113 (footnote 1). To this day, the Fathom f113 tops the subwoofer category in Stereophile's "Recommended Components."
JL Audio Fathom f212v2 powered subwoofer & CR-1 crossover
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.
KEF KC92 powered subwoofer
I was fascinated by Herb Reichert's adventures with the KEF KC62 subwoofer, so I borrowed one. Beautifully engineered, contoured, and finished and chock-full of cutting-edge technology, it would be welcome in any room and easily integrated into any system. However, it struck me as not just small but miniaturized, like the meticulously functional samples made for the traveling salesmen of a century past. Since its two force-canceling 6.5" radiators were the same size as or smaller than the midrange drivers in my main speakers at the time, I had low expectations and returned it without comment. That was in 2021.
I asked for a pair of KEF KC92s in early 2024 in the hope that these two relatively small subs would improve my system. Like the KC62, the gloss white cube with radiused edges and white diaphragms is an aesthetic match to our redesigned room, and the KC92 ($1999.99) is chock-full of the same cutting-edge technology.
