Wilson Audio Alida CSC Surround Speaker

Ultimate Emersion: Captivating multi-channel audio and cinematic experiences await those who choose surround systems. Alida CSC is ready.

Wilson Audio’s first wall-mount loudspeaker was designed as part of the W.A.T.C.H. (Wilson Audio Theater Comes Home) system. This foundational creation’s sole purpose was to serve as the surround sound component of a 5.1 installation while nonetheless offering the measure of frequency response and dynamic contrast that would complement Wilson Audio’s large floorstanding main speakers.

Over time, however, it became apparent that the performance of the W.A.T.C.H. Surround speaker was so good that people were using it as a wall-mounted speaker in two-channel music systems. Now found in bedrooms, offices, or other locations where space or architecture precluded the use of floorstanding loudspeakers, this need was recognized and the original Alida was born. Designed for main channel system playback while still maintaining its ability to excel in multi-channel surround applications.


Ultimate Emersion
Captivating multi-channel audio and cinematic experiences await those who choose surround systems. Alida CSC is ready. Surround sound content has come a long way from its infancy in the early 1980’s. Dolby Atmos systems allow for configurations like 5.1.2 or 7.2.4 (the last number refers to the number of ceiling-mounted speakers).
Because Alida CSC remains the uncompromising choice for state-of-the-art multi-channel audio and surround sound, we naturally developed and offer the Alida Ceiling Mount option to accommodate the most ambitious Atmos configurations.

Premium Ingredients
Found strategically nested between the critical interface of the X-Material enclosure and Mounting Bracket is another one of Wilson Audio's proprietary damping materials, V-Material. The utilization of these mixed materials ensures unmatched vibration control. By isolating the enclosure from the mounting surface, we've drastically reduced sympathetic resonances, ushering in a new level of system clarity. Novel in its properties, V-Material provides uncommon vibration control and module isolation, similar to the design philosophy found in the prestigious Chronosonic XVX and Alexx V.

CSC Tweeter
The CSC tweeter rear wave chamber is intricately printed in-house using an advanced carbon fiber composite on one of our many 3D printers. This bespoke tweeter was designed initially for the Alexx V and subsequently incorporated into the design of Alexia V and Sasha V and promises industry-leading high- frequency extension and ambient detail. Experience the profound silence between notes and immerse yourself in heightened harmonic richness.

Wilson Audio continues investing in the future and has done so again by having two customized, state-of-the-art capacitor winding machines built for our in-house capacitor manufacturing. These one-of-a-kind machines meticulously produce the most accurate, consistent, and best-sounding capacitors Reliable Capacitors (a division of Wilson Audio) has ever crafted. This is a testament to the dedication and passion we pour into every Wilson Audio product, in every step of manufacturing, and in every element of our creations.
With our newly designed AudioCapX-WA-Cu (copper) capacitors, built to industry-leading tolerances, the Alida CSC adds unprecedented resolution to your audio journey. This special copper version of the AudioCapX-WA capacitor, integrated into the tweeter crossover, unlocks a new level of high-frequency micro-detail and an open sense of air to your system's sound.

The greatest challenge for any surface-mount loudspeaker is accounting for the adverse interaction with the wall and ceiling, as well as degradation caused by the mount itself. This causes frequency nonlinearities—accentuating some frequencies and effectively masking others. Alida CSC minimizes wall/ceiling resonant interactions through a new thoroughly re-engineered mounting system.
Alida CSC’s new Mounting Bracket can be more fully optimized for both the time-domain and driver dispersion and provides up to 30 degrees of rotation. This adjustability allows for extreme adaptability especially in the most challenging installations.
