Optimus Pro CS-5 Subwoofer
A Deep Foundation for Your Sound
$29.00
In the era when home stereo was more than background music—it was a statement—the Optimus Pro CS-5 delivered the essential bottom octave that transformed listening rooms into live performance spaces. Designed by Radio Shack’s Optimus line, the CS-5 was crafted to partner seamlessly with bookshelf or floor speakers of the day, extending bass response with authority and clarity.
Design & Build
Housed in a sturdy acoustic suspension enclosure, the CS-5 combined compact dimensions with a weighty, substantial feel. Its cabinet, finished in rich walnut veneer with a classic woven grille, reflected the understated styling that blended effortlessly with 1970s living room décor.
Performance
At the heart of the CS-5 was a long-throw woofer engineered to reproduce low frequencies down into the 30Hz range—a depth not easily achieved by most standard speakers of its era. The sealed design controlled resonance for smooth, accurate bass, while the carefully matched crossover ensured natural integration with the listener’s existing speaker system.
Features
Acoustic Suspension Cabinet: Tight, controlled bass free from boominess.
Extended Low-Frequency Response: Adds foundation and impact to music and movies alike.

Seamless Integration: Designed to enrich Optimus bookshelf and floorstanding speakers, while remaining flexible enough for other brands.
The 70’s Promise
In an age when hi-fi was about presence and realism, the Optimus Pro CS-5 stood as a compact powerhouse. It offered listeners the depth of a live kick drum, the rumble of orchestral bass, and the warmth of jazz double-bass—all in their own homes.
Optimus—bringing the concert hall closer.
