There will be displays, demos, auction and raffle items, and freebies, plus lectures at the Firehouse, given by three prominent figures in audio engineering design: Nelson Pass…

London Phase 4 SPC-21005 (LP). Recorded September 22, 1964. Kingsway Hall, London. Marty Wargo, prod., Tony D'Amato, recording dir., Arthur Lilley, eng.
This is infuriating. Along comes the performance of Scheherazade that we've been waiting for, and the powers that be at London Records decide, God knows why, to bestow upon it the dubious blessing of Phase 4 recording. The sound is positively vast and cavernous, the bass booms, the highs scream, the harp sounds like…
Coolidge recorded her first single under her own name in 1969, when she was 24; this year sees the release of her latest album, Safe in the Arms of Time (Blue Elan BER1074). Do the…
"No, its a floor wax!"
"Dessert topping!"
"Floor wax!"
"Kids, don't argue—it's a dessert topping and a floor wax!"
Twenty years later, this Saturday Night Live routine still rings true. Experience has taught me that very few products can do two things equally well. Remember those jaunty amphibicars that sported propellers on their rear decks, letting you drive them straight into the lake after a bracing spin along the back roads? Unfortunately, they could neither corner well nor handle even the slightest chop. As for Swiss Army Knives, well, I…
In theory, the surrounds don't have to be equal to the front three channels—although this will probably change when five discrete digital channels become more…

Thiel loudspeakers are traditionally quite difficult loads for an amplifier to drive. The SCS2 is no exception, its impedance magnitude (the solid trace in fig.1) remaining below 5 ohms over almost the entire audio band. In addition, while the electrical phase angle (dotted trace) is low at almost all frequencies, it does become quite capacitive below 200Hz, which, combined with the low magnitude between 80Hz and 200Hz, will make high current demands on the partnering amplifier. The B-weighted voltage sensitivity is also only moderate at 85dB/2.83V/m, meaning that…
