| Could this be the best centre channel ever |
| |
The Polaris was formulated and engineered with a specific aim: a loudspeaker endowed with similar authority and dynamic range as Wilson’s reference floorstanding loudspeakers, but in a lowprofile package. When used as a center channel, Polaris seamlessly matches the acoustic signature of Wilson’s large loudspeakers – whether the main left/right speakers are Alexandrias or MAXXs.
The Polaris also provides an unprecedented level of musical accuracy in music systems and home theaters where its low-profile form solves architectural challenges, such as in those installations where a tall loudspeaker would block the view afforded by large windows, or would obstruct wide theater screens. Whether it is used as a center channel or as a main loudspeaker, Polaris matches the tonal beauty, dynamic speed, tonal sophistication, resolution, and sense of “thereness” of its taller Wilson brethren.
Among the technical innovations of the Polaris:
• New proprietary woofer. Working with an outside vendor, the Wilson engineering team designed a new ten-inch woofer. The design goal was to marry the high-speed, dynamic range, and low-frequency reach typical of
Wilson loudspeakers to a compact, low-profile cabinet. Transient speed and grand-scale weight and authority, typically mutually exclusive loudspeaker traits, are achieved by Polaris with effortlessness.
• An all-new upper-array geometry was designed to address the challenges of a low-profile design, with the two woofers mounted horizontally and flanking the midrange module. Two upper modules, one for
the two midrange drivers and the other for the tweeter, are each acoustically optimized in terms of volume, structural rigidity, and extremely low cabinet resonance contribution.
• Aspherical Propagation Delay. Achieving near perfect time-alignment at the listening position requires adjusting both the rotational angle of each module (for proper dispersion) and the time alignmentof the drivers (each module’s relative distance to the listener). Polaris joins the Alexandria and Maxx Series 3 as the only speakers with this feature. As in other Wilson loudspeakers, Wilson provides a nomograph with the necessary head adjustment data for any type of installation.
• Crossovers. When developing the crossovers for Polaris, the engineers applied new technology adapted from the Series 2 Alexandria, MAXX Series 3, and SashaW/P. The goal was to continue to reduce propagation delay jitter and to lower the noise floor. Polaris’s overall resolution, intertransient silence, dynamic speed and nuance rival MAXX and Alexandria.
• Front-firing port. Polaris’s bass port is located on the front of the cabinet. It can be placed near a wall, which is often needed when the center channel is located just beneath the movie screen, without compromising low-frequency linearity or transient speed.
• “S” Material midrange baffle. S-material, an epoxy resin laminate, is a new enclosure composite designed by Wilson in conjunction with the Sasha W/P project. When used in midrange and high-frequency baffles, S-material reduces measurable and audible noise and coloration in the critical midrange and lower treble. Wilson’s proprietary X-material is used in the balance of the enclosure walls, continuing Wilson’s practice of egineering utlra low resonant cabinets
