Critical Mass Systems Center Stage Ultra LS-2.25 Audio Feet Product Description: 

The Ultimate Enhancement

The Center Stage "LS" Series loudspeaker foot represents a breakthrough in mitigating loudspeaker resonance, born from years of experimentation and built upon our innovative Center Stage footer technology. With utmost confidence, I affirm that regardless of your system's quality, the Center Stage "LS" Series loudspeaker foot will elevate your listening experience to new heights. For systems already benefiting from Center Stage, the inclusion of Center Stage "LS" Series feet yields remarkable enhancements. Center Stage has the transformative power to enrich every aspect of audio reproduction, and the addition of Center Stage "LS" Series loudspeaker feet can be truly awe-inspiring. The rewards amplify with the caliber of the system, promising unparalleled results.

The development of the Center Stage "LS" was driven by several key objectives. Foremost among these was Critical Mass Systems' determination to pioneer an innovative solution to combat the degradation caused by excessive energy buildup resulting from vibration within loudspeaker cabinets. It's crucial to recognize that loudspeakers inherently produce vibrations, prompting manufacturers to devote significant time and resources to meticulous cabinet design and resonance management. While manufacturers meticulously address various factors such as loudspeaker weight, volume, driver array, leveling, and design advancements, the looming challenge remains daunting. Crafting a state-of-the-art loudspeaker foot presented a distinctive challenge, one which Critical Mass Systems triumphantly met.

The round design of the Center Stage "LS" Series loudspeaker foot is purposeful and strategic. Its rounded bottom ensures precise alignment with the floor and the bottom of the loudspeaker, maintaining contact even as the foot's height is adjusted to achieve either a level orientation or a raked-rear configuration—a feat unattainable with traditional spikes.

At the core of this design is the massive height-adjustable spike comprising the entire lower ball structure. By rotating the ball clockwise, the loudspeaker is raised, while counterclockwise rotation lowers it, offering approximately 0.25 inches (mm) of adjustment range. The ingenious 3-to-1 turning ratio minimizes the torque required for adjustment, while a built-in safeguard prevents overextension and detachment of the internal mechanism under load.

During operation, the black outer shell effectively isolates vibration from passing upward through the foot, ensuring it is directed through predetermined channels within the foot structure, where it can be effectively minimized. Simultaneously, the upper shell is engineered to dissipate resonance and heat from the loudspeaker, contributing to reduced entropy and achieving remarkably low distortion and a flat frequency response.

Aligned with the objectives of the Center Stage system, the Center Stage "LS" Series loudspeaker foot aims to unveil the exceptional engineering inherent in your loudspeakers. For existing Center Stage users, incorporating the "LS" Series under their loudspeakers promises a level of performance that surpasses imagination.
