Sorry, Däfosis THE standard, used by Paul himself (and many others) at audio shows to demo equipment.
I was particularly impressed by the way the Pioneers handled themselves on challenging bass material. One torture test I’ve used for years is Dafos (Reference Recordings RR-12CD, out of print). “The Gates of Dafos” is particularly revealing. At the end of this track, a large drumset falls to the floor, with much subterranean rumbling and shaking. I have overloaded some otherwise very good subwoofers with this cut. But at a reasonable yet still impressive volume level in my large home theater, the TZ-F700s sailed right on through. They also produced a most impressive deep-bass shudder, the sort of sound produced by this material only on very good subwoofers.
Background by Keith Johnson of Reference Recordings:
Holt: On your recording of Däfos , what kind of instrument produced those awesome bass thuds?
Johnson: Well, it isn’t entirely one instrument, but a big, circular grouping of percussion instruments that was used for Grateful Dead concerts. They call it “The Beast.” A lot of drums are hung from a big circular pipe, and Mickey Hart stands inside the circle to play them. But a bass drum wasn’t really what was making those bass thuds. A lot of that bass was from reverberation in the hall. Then during the setup of the The Beast, Mickey Hart lifted the entire structure and let it drop to the stage, which made a terrible noise. He was fooling around, really, but when we heard the result on the tape we decided it had to go onto the record. This particular passage caused great grief to Doug Sax (who mastered Däfos ), forcing him to dig into his bag of tricks to keep the cutting stylus on the lacquer.
