My last blog post described a visit to KEF, however, I took a few more photographs on the day than I was able to include in the post, so I thought I’d put that right with a follow-up post majoring on, in no particular order, a few of the unused pictures. Click on each one […]

I’ve been measuring speaker performance ever since I washed-up at Mordant-Short in the early 1980s as a raw design graduate. One of the first things I learned was how to use a set of classic Brüel & Kjær acoustic measurement equipment comprising a measuring microphone, a combined oscillator/preamp/analyser (one of these) and a paper chart recorder (like this).
