Vandersteen 1Ci Loudspeakers



The Model 1Ci is living proof that designing and building a great entry-level speaker doesn’t require as much ingenuity and skill as a cost-no-object flagship- it requires even more! The Model 1Ci is a time- and phase-correct speaker constructed in such a way that the alignment and positioning of the drivers allow a point-source wave front and maximize the phase coherence of the loudspeaker at the listening position. Dimensional Purity in a shockingly affordable full-range speaker.

The active components used in the Model 1Ci combine classic strength and durability with innovative design and construction. The woofer uses the same type of cast-metal basket used in costly esoteric loudspeakers. The cast-metal basket’s inherent rigidity and superior vibration resistance increase cone movement accuracy and reduce sympathetic resonances for cleaner and more natural sound. A filled polycone is used to insure high stiffness, superior internal dampening and greater neutrality than metal alloy, woven plastic or treated paper cones. The stiff, low-weight polycone resists flexing under all drive conditions for lower distortion and increased detail. The Model 1Ci’s transmission-line port extends bass response while operating much closer to the ideal than any of the more conventional ported or passive designs.

The metal alloy dome tweeter is a dual chamber design to improve range and linearity. It is critically damped to extend the high frequencies past audibility without the excessive ringing associated with open or underdamped metal dome tweeters. The specific alloy used for the dome was chosen for its superior strength and resistance to break-up compared to common fabric and plastic domes. The quality materials and advanced features of the Model 1Ci’s tweeter result in smooth and accurate response throughout the audible range.

The crossover of the Model 1Ci is a transient-perfect, first-order network designed to preserve the phase integrity of the original sound. It is compensated to allow the drivers to operate in absolute phase with each other while maintaining flat amplitude response. This gives the Model 1Ci more precise imaging and a more stable soundstage than conventional two-way speakers using out-of-phase drivers. The crossover’s computer grade components, including film capacitors in the signal path, are hand soldered on a double-sided, plated-through PC board for enhanced consistency and reliability.

The baffles holding the drivers on the Model 1Ci are as small as possible to eliminate virtually all of the early reflections that affect dynamic speakers with conventional flat or low diffraction baffles. Reducing both early reflections and edge diffraction improves imaging and enhances the openness and transparency of the speaker. The enclosure of the Model 1Ci is constructed of MDF, a pressure-formed material that effectively resists vibration and controls cabinet resonances. Broad spectrum, low-Q resonances are controlled so as to cancel rather than become additive.

To insure consistency, each speaker is FFT analyzed for correct response and performance compared to a model reference prior to leaving the factory. The Model 1Ci combines superior components, innovative engineering and quality construction for exemplary performance and unparalleled value.
