C20 Loudspeaker

The C20 center channel is the perfect complement to a pair of P20 left and right channels, or where a center channel with a small footprint is desired. The C20 is not a line source like some of our larger models, but is instead a point source loudspeaker. The vast majority of loudspeakers available in the world are point sources, meaning that they radiate their sonic energy outward in an expanding sphere, as though from a point in space.

The C20 can be used in in-wall (C20i), on-wall (C20m) or freestanding (C20) applications. Sharing the same driver technology, it is timbre matched and can be combined with other Sage Series in-wall, on-wall and freestanding models as desired for the specific installation. All versions are constructed entirely from aircraft grade aluminum. Slim and elegant in design, the freestanding and on-wall versions of the C20 blend nicely into a variety of décors where traditional loudspeakers might otherwise intrude excessively on the room’s appearance. Their clear anodized interlocking trim bezels and matte charcoal colored cabinet convey an exquisite balance of industrial design and build quality unique among consumer loudspeakers. The narrow aspect C20i in-wall design becomes one with the wall, via its paintable grill and bezel, while its all aluminum chassis and integral back box enclosure ensure optimal and consistent performance regardless of mounting environment.

As you would expect, the C20 center channel is identical to the performance of the P20. The C20 uses two of the same proprietary high operating pressure woofers found in its larger Sage Series siblings. A groundbreaking 2-inch planar magnetic tweeter is responsible for this series’ characteristic transparency, detail and instantaneous dynamics, handles the midrange and high frequencies, and extends all the way down to 650 Hz. The diaphragm is actually square, but the acoustic lens optimizes the dispersion at the highest frequencies while allowing the midrange frequencies to pass through without attenuation. The result is excellent, uniform horizontal dispersion throughout its operating range. This amazing PMD tweeter may not play as loudly as the larger ones in the other Sage models, but it will still outperform a conventional 1-inch dome tweeter, while handling almost two additional octaves of the midrange.

The C20 center channel provides outstanding performance and mates seamlessly with the P20 Sage Series speakers. The task of the center channel can be challenging depending on the source material, often resulting in compression, distortion and lack of intelligibility. Employing planar magnetic drivers for the majority of its output, it is incredibly detailed and dynamic, and does not suffer from the sonic compression that plagues many conventional loudspeaker designs. The C20 provides lifelike dynamic music and voice reproduction that belies its slim profile and compact design. Capable of the volume and dynamics normally associated with a live performance and accompanied by excellent horizontal dispersion, the C20 measures up to the requirements of a Sage Series P20 based multichannel system. The C20i, C20m and C20 architectural center channel loudspeakers deliver high definition sound that is a perfect complement to high definition video, while opening up new worlds of sonic performance for your musical enjoyment.
