THE MODEL 2Ce Signature
TRUE TO SCIENCE AND MUSIC
Since 1977, Vandersteen Audio has designed and built innovative loudspeakers using advanced concepts such as minimum-area baffles for driver mountings that virtually eliminate cabinet edge and grille diffraction anomalies and mass alignment of driver elements to insure proper time arrival. Vandersteen Audio was the first loudspeaker manufacturer to use the Gen-Rad 2512 FFT (Fast Fourier Transform) Computer Analyzer originally developed for the aerospace industry, for in-house research and development and remains a leader in interfacing complex computerized analysis of loudspeaker parameters and performance with practical design and engineering.
The Model Two benefits from our years of experience designing and building loudspeakers of unparalleled value and performance. It couples proven technology with advanced materials, construction and design for a speaker system that is always true to both science and music.

SPECIFICATIONS
Even with advanced test equipment and complex computer analysis, loudspeaker design remains an incomplete science. No measurements currently available can fully convey the sound of a speaker or provide a meaningful comparison between differing designs.
The truth is in the listening.
IMPEDANCE:
7 ohms nominal 4 ohms minimum.
EFFICIENCY:
86dB with 2.83 volts of pink noise input at 1 meter on axis.
RECOMMENDED AMPLIFICATION:
40 to 160 watts per channel into 8 ohms.
FREQUENCY RESPONSE:
29Hz to 29kHz 3dB
32Hz to 21kHz 1.5dB
By FFT step function.
DISPERSION:
29Hz to 16kHz 3dB 30 degrees off axis.
CROSSOVER FREQUENCIES:
600Hz and 5kHz. First-order, 6dB per octave
Dual inputs allow bi-wiring with a single stereo amplifier or
passive vertical bi-amplification with two identical stereo amplifiers.
INPUT CONNECTIONS:
2 pair of female banana jacks.
CABINET FINISH:
Hand-matched and finished natural oiled wood veneers.
VIDEO APPLICATIONS:
Main or surround speakers
The Model Two is not magnetically shielded and should
be positioned at least 10 inches away from a direct view television set.
PHYSICAL SPECIFICATIONS:
39.75" high x 16" wide x 10.25" deep 70# gross, 60# net
