The "Bass Management Boot Camp" article about subwoofer setup that I wrote for the November S+V inspired an in-turn inspiring e-mail from reader Bruce Erwin. Bruce recalled his days setting up sound systems when he'd use a 1.5-volt battery to test subwoofer phase. If the sub and main speakers were in phase, he'd hear a single thump when he connected the battery to the wires leading to the sub's terminals. If they were out of phase, he'd hear a double thump.

That's with passive subwoofers, though. Almost all of today's subs have built-in amps, so this method wouldn't quite work with them. Still, it got me wondering if I could come up with a simpler phase check than the ones I suggested in the article, which required either measurement or careful listening. My e-mail convo with Bruce gave me some ideas and, ultimately, a method that's simpler than my original. And all you need to do it is a piece of free software and a meter you've either already got or can get for nothing.

Light is one of those intangible things that is stuff and whatnot. Wait, no it isn't. It's light. As in, "Aziz, LIGHT!"

On the one hand, it's either on or it's off. On the other hand, it's half-on, half-off, and you've programmed it to go half-off and half-on again at the touch of a button.

If you don't have kids to turn lights on for you (or maybe you have kids, and they don't turn them back off), Lutron has a host of products to make life a little easier. How much easier is best explained by experience. Which brings us to the aptly named Lutron Experence Center.

I like writing about tablets about as much as I like getting kicked in the privates, but when big companies announce big dumb things, I feel obliged to cover it. Last week it was Microsoft, with their could-be-awesome-but-probably-won't-be Surface tablet. This week it's Google and the Nexus 7 (and the Q streamer). As usual, the lazy tech writers made hyperbolic comparisons, claiming it a Kindle Fire "killer" and... oh WTF IT'S THE CONTENT.

There’s something your phone can do (probably) that can not only save you money, but make vacations more enjoyable (maybe).

They’re called SIM cards, and they’re not much discussed in the States, but are commonplace pretty much everywhere else.

To find out why you should care (potentially), read on.

Whenever I'm in the Pacific Northwest, I like to stop by Vancouver's Innovative Audio and visit my friend Gordon Sauck, one of the true gurus of vintage audio gear.

I recently completed a review of the TC-P55VT50 from Panasonic, look for it in an upcoming issue. Performance wise, it was damn near incredible: One of the best contrast ratios I’ve ever measured, accurate color, and deep blacks.

However, there was one “feature” that really pissed me off.

Advertising.

If I had been sitting across from someone I'd never heard of who was starting yet another headphone company, I'd have probably steered the conversation to the weather or Lady Gaga's latest outfit.

I watch one sporting event each year (OK, two if you count the sportball game between the commercials of the "Superbowl"). This one event takes place in a tiny village in western France. An epic battle of men and machines, of endurance and stamina, of danger and skill, fought against weather, distance, and time.

I of course speak of le mythique, le légendaire, le grand Circuit de la Sarthe et les Vingt-Quatre Heures du Mans.

Or simply,

Le Mans

I use my iPod to deal with crowds. If you’re like me, sometimes you just like cranking up some tunes to push the world out to more acceptable distance. This is especially true trying to shop during the holiday season.

So for the always-hectic Black Friday weekend, I figured I’d put together a few songs that are, shall we say, not sticky-sweet holiday shopping tunes. Drown out that Bing, Nat, and Perry, and power through the season with these.

In the late 1990s, a product manager from Zenith brought me the company's first HDTV set for review. After an afternoon spent checking out the TV - an engineering marvel for its time - I told him how impressed I was with it. "Yeah, we'd sell a ton of them if it said 'Sony' on the front," he wisecracked.

Many audio manufacturers have addressed the changes that room acoustics afflict on our sound systems. But until a week ago, I knew of no audio manufacturers who’ve addressed the changes that our hearing causes on sound.

Like every other Sound+Vision writer, I’ve seen a lot of 3D TV. But I never saw so much 3D TV as I did last night, when I walked into South, Los Angeles’ first 3D sports bar. Everywhere I looked, I could see a Vizio flat-panel TV showing 3D programming—sports mostly, of course, but also games and a couple of Blu-ray Discs.

"It's great, I never have to pay for music again!" Such was the exclamation from someone I know in regards to Spotify.

I was baffled at first, but the more I thought about it, the more it annoyed me. Because my acquaintance isn't alone in this thought. It's prevalent among many, and it extends beyond music.

What they're really saying is: "I want you to entertain me, but screw you for trying to make a living at it."

What the what?

A few weeks ago I laid out all the reasons why I thought the "free" music streaming services Spotify and MOG were ghastly, malicious succubi suckling at the teat of artistic talent.

Since that post, I've been presented countering opinions by musicians and music producers alike, and I've come away with a slightly different opinion. Perhaps I went too far.

Perhaps they're not ghastly.
