The Vandersteen Model One
A precisely aligned dynamic design, blending common-sense innovations with proven technology, gives the Vandersteen Model One many advantages:
Computer-optimized driver placement and cabinet design virtually eliminate the interference patterns usually associated with multi-way speakers
Lack of out-of-phase rear wave cancellations and interpanel interference allows many placement options in the listening room
Basic design concepts produce exceptional efficiency, extended dynamic range, and a point-source wave front for correct sound-stage replication
Overall polar response pattern resembles the studio microphone pick-up pattern for better imaging and a broader listening area.
High efficiency and smooth impedance curves provide unlimited amplifier compatibility
Driver design eliminates "edge clamping" distortions present in all planar diaphragm loudspeakers
By correcting for "real-world) conditions - such as cabinet losses, thermodynamic losses, and active/passive transfer anomalies - the Vandersteen Model One function more like an ideal speaker than do conventional designs. Such performance is possible because computer analysis guided the driver selection process, and each speaker was tested for minimal cone break-up, internal diffraction, and out-of-band phase irregularities. An innovative circuit design permits these drivers to operate in absolute phase with each other, preserving the dimensions of live music. The result; a level of sonic purity and listening enjoyment that far exceeds the modest cost.
The Active Components
Custom manufactured drivers (an 8" die-cast basket with curvilinear polycone woofer and 1" dual chamber polymer dome tweeter) ensure linear operation well beyond the cutoff frequency for near seamless blending. The woofer system, including rear slot loading, comprises a fourth-order filter. The tweeter incorporates low moving mass for excellent transient response and extended bandwidth.
The Crossover
The transient perfect first-order dividing network uses air core inductors with polypropylene and polycarbonate capacitors in the signal path. Phase compensating networks allow ideal transient response, impedance-compensating networks avoid the frequency response irregularities associated with typical crossovers.
The Construction
The Vandersteen Model One is constructed entirely from a wood product far denser than particle board to minimize induced resonances. FFT (Fast Fourier Transform)analysis during all stages of assembly guarantees that each speaker matches its mate within .5 dB for precise imaging.
