Chris Hagen is acoustic systems development engineer for Velodyne, a company that, despite its recent forays into headphones, has been primarily a subwoofer specialist since its founding in 1983. Chris has also worked as an engineer for the consumer division of JBL, and for M&K Sound. Excerpts from this interview appear in the feature story “Subwoofers: The Guts and the Glory.”
S&V: What’s the most important in a subwoofer: the driver, the enclosure, or the amplifier?
CH: Being a system engineer, I believe all of it’s important. A poor-quality part in just one of the areas can mess up the whole product. For instance, no sub with a leaky enclosure is going to sound good no matter what amp or driver you use. Or if you tune the sub in an environment [room] that’s not appropriate to tune in, it’s going to sound bad regardless of the components you use.
S&V: Do you have a preference for ported, sealed, or passive-radiator subwoofers? How do the design decisions differ among those three?
