All of which makes, The Wonderful Sounds of Christmas, Acoustic Sounds fabulous new Christmas music double LP set—pressed on separate red and green 180 gram vinyl LPs—such a pleasure to listen to. I have never heard Nat King Cole’s “The Christmas…
Driving the E11s with a sinewave oscillator revealed minor cabinet resonances at 30Hz and 90Hz. At 200Hz, the cabinet started to vibrate and take on a buzzing sound. At 220Hz, the buzzing produced by the cabinet was louder than the tone produced by the woofer. This will certainly be audible as an inability to distinguish the pitch of notes near this area. Another lower-amplitude resonance was heard at 380Hz.
Fig.1 shows the E11's impedance magnitude and phase angle. The impedance is quite high, dropping to 6 ohms in the lower treble only over a narrow…
It should be realized that no DAC is perfect. The conversion process from the digital to the analog domain…
Description: Two-way, stand-mounted loudspeaker with 6½" woofer and 25mm aluminum-dome tweeter. Bass alignment: reflex (rear-firing port). Crossover frequency: 3kHz.

Price: $349/pair (1990); no longer available (2015). Approximate…
The Accuphase DC-91 had a maximum output level of 2.64V from the balanced outputs, 2.54V from the single-ended outputs. The output impedance measured a low 49 ohms (balanced) and 52 ohms (unbalanced) at any audio frequency. These low output impedances suggest that the DC-91 will drive any preamplifier and cable with ease, and will not be loaded down by low input impedances. The DC-91 doesn't invert absolute polarity from the single-ended outputs, but the XLR connectors are wired with pin 3 hot—contrary to the AES standard of pin 2 hot. This will cause the DC-91 to…
