I'll be honest, I can think of few things less sexy to review than an antenna. This isn't because they're not useful, it's just without a lot of specialized equipment, there isn't much I can say about them.

I live in The Valley, with a direct line of sight to the HDTV transmitters that cover all of Los Angeles. On the clear day each year, I can see Mt. Wilson from my front door. TV reception is so good, I could stick my finger in a TV's antenna input and my dome could probably pull in a signal. Picture that for a second.

But The Leaf by Mohu is actually kinda cool, and looks very different from any antenna I've seen.

Hanging out at the recent Rocky Mountain Audio Fest, I listened in on a conversation that S+V writer Mike Trei was having with an audio manufacturer who’s getting into the headphone biz.

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.

I predict that 2011 will be for audio what 1962 was for the art world. In 1962, Andy Warhol’s first solo shows in Los Angeles and New York swept away the prevailing aesthetic ethos of the era, demonstrating to the world that a Brillo pad box could be a work of art.
