Five Subwoofer Masters Explain How They Work Their Magic
Subwoofer design has undergone a revolution. No, the physics of woofers, amplifiers, and enclosures haven’t changed. But new technologies have made it possible to push the bass-ic laws of nature to their limits, such that the best of today’s inexpensive
subwoofers can outperform many of the top models from 15 or 20 years ago.
Affordable digital audio processing lets designers tune subwoofers in ways the engineers of the 1990s could only have imagined. High-efficiency amplifiers pound out powerful bass from boxes hardly bigger than a basketball. New speaker drivers use high-tech materials to produce sound levels that would have pushed older models way past the breaking point.
Since things are so different now, we thought this would be a great time to revisit some of the fundamentals of subwoofer design and examine how the old rules might have changed in the digital age.
Life is good. Having just moved into a house with a room for a dedicated home theater, it was time to get set up. More to the point, time for shopping. Usually, the last thing I want to do is to buy furniture, but the search for the perfect chairs for my home theater became my quest. Seeking perfection, I pored over furniture catalogs, websites and scoured any furniture in my path. A woman’s home theater is her castle, right? I already had furnished my girl-cave, I mean home office, and the A/V room, although last on the decorating list, was in my mind, the most crucial.
Showtime Anytime lets you stream Showtime TV shows and movies to many devices and now includes Roku. DISH subscribers are left out. Here's a review of the CBS and DISH feuds over the years and why DISH subscribers probably won't be able to stream Showtime anytime soon.

THE VERDICT
A small, or at least smaller, subwoofer that goes truly low, loud, and clean—and looks sharp doing it.
What can you say about a subwoofer? It goes this low, that loud. It has these jacks, knobs, and features and is yea big and costs yon dollars. And really, that’s about it; almost all other discussion is so much verbiage.
Response “flatness” from a speaker covering barely two octaves is of little consideration unless a sub is horribly peaky (a few are), especially since room effects invariably dwarf such variations anyway.
There’s not much gained by the contemporary setting to offset the oddness of having Shakespeare’s characters seem like a bunch of Wall Street stockbrokers speaking strange in the Hamptons as if in a Woody Allen comedy, but otherwise the Bard’s words flow well enough from the pretty mouths of the cast.
There’s been a lot of talk lately about premium streaming music services, especially now that Dr. Dre, (creator of Beats headphones) has thrown his hat into the ring. It’s a compelling proposition Dre makes, especially considering that he single handedly re-invented and reinvigorated the headphone industry. But as an observer, I find myself exceptionally torn about the idea of a streaming service both as a consumer and creator of media.

THE VERDICT
These full-size headphones are comfortable, sweet sounding, and suitable for portable signal sources.
Some companies jump into the now-trendy headphone category on a wing and a prayer. Sony, on the other hand, is the steward of Sony Music and the master of numerous audio product categories, including a long history in headphones. So a set of midpriced ’phones from Sony raises high hopes. With the MDR-1R, they are largely fulfilled. I like these headphones, not because they’re perfect, but because they feel right.
It’s the summer of 1964 and Guy Patterson is back from the Army and working in his parents’ appliance store in downtown Erie, Pennsylvania. When the shop closes down for the night, Guy puts on his favorite jazz album and plays the drums to his heart’s content. Some old friends have started a band, and when their regular drummer breaks his arm, they come looking to Guy to fill in for a college talent show—which they win thanks to Guy’s decision to pick up the tempo in their breakout song. They end up getting a gig at a local pizza parlor and eventually catch the eye of a roving talent scout. Before they know it, their song is on the radio, they’re signed by Play-Tone records, and they’re off to California.
Q I recently learned that my television’s 120 Hz feature is global—when I turn it on, it remains on for all sources. I'm not a fan of this because I don't like seeing the “Soap Opera Effect” on TV and movie sources, though I do like it when playing videogames because the higher frame rate gives them a silky-smooth look. Here’s my question: Do you know of any TVs with a 120 Hz feature that can be turned on or off for specific inputs? —Ricky Meadows / via email
Pete Townshend was on a spiritual mission, determined to produce a rock opera that would reflect his own path to enlightenment. His band mates in The Who were initially wary, but once they understood the multifaceted story of a deaf, dumb, and blind kid who sure played a mean pinball, there was no turning back from climbing the mountain. The epic sprawl of 1969’s Tommy catapulted The Who forever into the rock ’n’ roll stratosphere. And now Tommy gets a fuller archival due on this four-disc 45th anniversary Super Deluxe box set, achieving yet another new-vibration milestone on Blu-ray. (More on that disc’s groundbreaking surround mix in a moment.)
