S&V: What’s the most important aspect of a subwoofer: the driver, the enclosure, or the amplifier?
AW: I don’t think there’s any one thing that makes a good subwoofer. A major determiner is that the design is balanced, so everything’s made to work together. To say the driver is most important, well, I can make a woofer that handles 1,000 watts all day long, but if I stick it in a cabinet that doesn’t load it properly, there’s no point in having that glorious woofer in the system.

I often worry that people get the wrong idea when I praise a speaker for sounding "flat." By this I mean its frequency response is flat, which is a good thing. But if you ask the man on the street, I bet he'd equate flat sound with lifeless sound.

It's high time I explained what frequency response is and why flat frequency response is desirable in audio products. Not only will I explain why non-flat response is bad, I'll demonstrate it to you with some audio files I cooked up just for this article.

My, how times have changed. Back when vinyl records were king and a 25-inch-diagonal TV screen was considered big, here's how you had a good time in the backyard: a keg of beer, burgers on a charcoal grill, and your roommate's big, ugly speakers (carted out from the living room) blasting Rush (Geddy Lee, et al) until the conservative neighbors call the cops. A decade or so goes by, and the fun gets more sophisticated: a cooler of imported beer (maybe a margarita machine), steaks on a gas grill, and a big, ugly boombox belting out Rush (Limbaugh) until the liberal neighbors call the cops. Today, it's likely to be takeout from a local BBQ joint, a mini-fridge full of hard lemonade, and steam from the hot tub mingling with big-band music from outdoor speakers hidden somewhere in the (twice-monthly manicured) foliage.
