Interviews

Last spring while in San Francisco to speak to the S.F. Audio Society, AnalogPlanet editor Michael Fremer had the opportunity to speak on camera with Siegfried Linkwitz, whose name will be familiar to many audio enthusiasts as the co-inventor of the Linkwitz-Riley crossover network.

Mr. Linkwitz's designs are available as DIY (do it yourself) kits that you can read about on the Linkwitz Labs website. The LX521.4 shown in the video can be built DIY from a kit for around $3300, including a miniDSP 4x10HD equalizer/crossover. The sound in Mr. Linkwitz's untreated living room was full bandwidth, detailed, 3 dimensional and smooth.

Yes, you can great, full range sound without breaking the bank. This is somewhat off-topic for analogPlanet but you'll find it worth watching.

Mr. Linkwitz's listening room. Note the lack of acoustical treatment yet the staging and imaging were outstanding.

Despite being a science/measurement oriented innovator one thing that Mr. Linkwitz said during the interview is something everyone reading this should keep in mind when reading measurements:

"What is important to the eye is not necessarily important to the ear. Why should it be? Nature makes sure each does its job and does its job perfectly. You get cues from the eye but some things that look gross in the frequency response, the ear says 'I don’t care'."

Please enjoy this conversation with Mr. Linkwitz. Incidentally the electronics driving the system was a PowerBox 6 pro, which includes a preamp. A/D converter, DSP, 6 DACs/ and 6 Hypex NCore power amplifiers. Probably not an analog enthusiast's cup of swill but it too is reasonably priced at around $3000 for all of that and you can read all about it here.
