Audiofly is a cool new brand with a retro look. Its website is filled with pix of recent-vintage tattooed hipsters, but its IEMs have molded-plastic perf grilles reminiscent of the 1960s portable radios I grew up with.

They’re still at it. A recent issue of Stereophile featured a sidebar on “13 Products Julian Hirsch Got Right” — implying, of course, that Hirsch got most products wrong. Poke around audio websites and you’ll probably see his name mentioned, often with scorn. But the man retired as technical editor of Stereo Review (Sound+Vision’s forebear) way back in 1998, and passed away five years later. What did he say so long ago that continues to attract attacks?

When pro audio technology invades home theaters, it’s usually in the form of a recording monitor repurposed for consumer use. Pro Audio Technology comes at it from another direction: It’s bringing P.A. system technology into the home.

For subwoofer designers, the laws of physics boil down to: Small box, low cost, high output — pick any two. You can always shrink the enclosure, but to get decent output from it, you’ll need a high-powered amp and a beefy driver. And if you shrink the box way down, as Sunfire did with its new Atmos subwoofer, you’ll need to go even more extreme.
