Wide soundstage and crisp, clear dialogue

Cambridge Audio's S50 center channel speaker is more than capable of handling the sonic demands of home theater dialogue. Hear your favorite Hollywood star whisper sweet nothings as if she's addressing only you, or pick out the plunk of each rain drop before the ninjas attack. It's hard to beat this speaker's wide soundstage, smooth highs, and detailed midrange — which come with a surprisingly affordable price tag. The S50 is perfectly matched with the rest of Cambridge's S-series speaker line, and works best when used in a home theater system with the S70 floor-standing speakers or S30 bookshelf speakers. Just add the matching S90 powered subwoofer to get the full punch behind those crazy drum solos and explosions in your favorite songs and movies.

Designed and engineered with passion

All of Cambridge Audio's S-series speakers are carefully designed and tested at their London facility by a team of engineers fueled by a passion for incredible sound. The S50 uses a 1" soft dome tweeter for silky smooth highs. It features a state-of-the-art motor system with a neodymium magnet and critically selected voice coil assembly. Dual 4" composite woven mid/woofers deliver accurate midrange and powerful, yet controlled bass with minimal distortion.

A rigid phase plug at the center of each woofer cone improves the S50s' off-axis response, so you can enjoy seamless audio even if you're not sitting directly in front of your TV or sound system. The custom-designed second order crossover sends the right frequencies to the right drivers to keep your music and movie soundtracks sounding faithful to the studio original. And the solidly braced MDF cabinets help prevent unwanted resonance from coloring the sound.

Your home theater's most important speaker

The center channel speaker is the workhorse in a home theater system. It has to reproduce clear dialogue and special effects that keep your eyes and ears glued to the movie action. A high-quality center speaker is a great investment for any surround sound setup. Try to choose one that's as closely matched as possible to your front right and left speakers, so that as sound moves across the front stage, it stays seamlessly realistic.

Driver Technology

1" Soft-Dome Tweeter: The S50 center-channel loudspeaker features a 1" soft-dome tweeter for smooth, accurate highs. The tweeters use high flux density, self shielding neodymium magnet assemblies for improved sensitivity and better dynamics.

Dual 4" Mid-Bass Woofer: The S50 center-channel loudspeaker utilizes dual 4" woven polyfiber cone mid-bass woofers for dynamic mid & bass response. Each mid-bass woofer uses a rigid phase plug for improved off-axis integration. The 4" mid-bass woofers also feature a high-quality rubber surround edge for reliable cone termination. In addition, an optimized magnet motor-assembly is used for extended lower frequencies.

Two-Way Crossover: The S50 center-channel loudspeakers utilize a 2nd order, 2-way crossover to deliver high-frequencies to the tweeters and mid-/low-frequencies to the mid-bass drivers. High-quality laminate core inductors give cleaner bass with improved dynamics, while polypropylene film capacitors in critical path areas give a high-resolution high frequency response.

Frequency Response: The S50 center-channel loudspeaker has a frequency response rating of 80 to 20,000 Hz.

Power Handling: The Cambridge Audio S50 center-channel loudspeaker can handle between 15 to 80 watts (RMS).

Enclosure Design

Bass Reflex: The Cambridge Audio S50 center-channel loudspeaker employs a bass reflex (ported) enclosure with two rear-firing ports for greater efficiency and bigger bass response.

MDF Cabinet: The S50 center-channel loudspeaker features a rigid MDF cabinet with internal cross-bracing to prevent any unwanted distortion caused by vibration and resonance.

Wood Veneer Finish: The S50 center-channel loudspeaker are available in a black or dark oak wood veneer finish.
