If you have not already done so, we recommend you read our Sage Series Overview before moving on to the specifics of the Sage model below.
The C38 is the Sage Series flagship center channel where horizontal placement of the loudspeaker is a requirement of the installation. In rooms where a large acoustically transparent screen is being used, the C150, L150, L100, or L75 line source models can be used as a center channel in its upright position (it is not possible to use the line sources horizontally).
The C38 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 C38 can be used in in-wall (C38i), on-wall (C38m) or freestanding (C38) 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 C38 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 C38i 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 C38 center channel is virtually identical to the P38. Though they look quite similar, the MTM tweeter is rotated 90 degrees for optimal dispersion (as is the case with the C20 compared to the P20). Four of the same proprietary high operating pressure woofers used throughout Sage Series models mate with a unique MTM Planar Magnetic Driver array for the midrange and treble. The MTM array provides the same level of transparency, detail, and instantaneous dynamics as the 24-inch Planar Magnetic driver used in the L150 (in multiples), but is a much smaller package optimized for the space requirements associated with the P38 and other more compact Sage Series models.
As with all Sage Series systems, the 7.3 channel SC-1 System Controller is the heart of the system. It provides the active crossover between bass and midrange/treble, system-specific EQ, as well as Audyssey™ MultEQ® XT room correction on all 17 output channels for consistent no-compromise performance in every installation.
The C38 center channel provides no compromise performance and mates seamlessly with other 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 C38 provides stunning, 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 C38 measures up to the requirements of a Sage Series based multichannel system. The C38i, C38m and C38 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.

Environmental Testing Data View»
Designing reliable audio products involves the exhaustive and thorough evaluation of every component part used in their construction. Every material type, adhesive, and finish coating must be chosen carefully.
In order to insure the highest degree of reliability of our products when exposed to the most extreme environmental conditions, Wisdom Audio has submitted all key components to severe environmental testing. As many of the transducers are new to a large part of the audio market, the question of reliability is raised from time to time, especially as it relates to marine applications.
The components were exposed to the following conditions in a variety of test chambers by Environmental Associates of Chatsworth, California.
- Exposure to 85 degrees Celsius at 85% relative humidity for a period of ten days.
- Temperature cycling from minus 40 degrees Celsius to plus 105 degrees Celsius with a two hour dwell time at each extreme for a period of five days.
- Salt fog exposure at 95 degrees F with a 5% mist of salt solution for 48 hours.
The test results were very interesting and useful, allowing us to make minor modifications to what otherwise endured these extremes beyond even our own expectations.
