Overview

Our take on the Cambridge Audio S20

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. Each S20 speaker 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. The 4" woven composite woofer delivers accurate midrange and powerful, yet controlled bass with minimal distortion.

Great sound and simple good looks for any room

Cambridge Audio's compact S20 bookshelf speakers are no strangers to sonic agility and power. Delivering a deliciously crisp treble and surprisingly deep bass, these monitors are ideal as part of a home theater setup, as a stereo music system, or as hi-fi desktop computer speakers in smaller rooms. With their good looks and versatility, the S20 speakers make a great budget speaker pair. Want even more bass? Just add a powered subwoofer and listen to these babies really come to life!

A rigid phase plug at the center of the woofer cone improves the S20's off-axis response, so you can enjoy seamless audio even if you're not sitting directly in front of your TV or sound system. And the custom-designed first order crossover sends the right frequencies to the right drivers to keep your music and movie soundtracks sounding faithful to the studio original.

The solidly braced MDF cabinets help prevent unwanted resonance from coloring the sound. Plus, the pair is video shielded for safe placement next to older tube TVs or computer monitors.

Driver Technology

Two-Way Drivers: The Cambridge Audio S20 bookshelf loudspeakers employ a two-way speaker design.

  • 1" Soft-Dome Tweeter: The S20 bookshelf loudspeakers feature 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.
  • 4" Mid-Bass Woofer: The S20 bookshelf loudspeakers utilize a 4" woven polyfiber cone mid-bass woofer 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 S20 bookshelf loudspeakers utilize a 1st 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 S20 bookshelf loudspeakers have a frequency response rating of 80 to 20,000 Hz.

Power Handling: The Cambridge Audio S20 bookshelf loudspeakers can handle between 15 to 80 watts (RMS).

Enclosure Design

Acoustic Suspension: The Cambridge Audio S20 bookshelf loudspeakers employ an acoustic suspension (sealed) enclosure for deeper, accurate bass.

MDF Cabinet: The S20 bookshelf loudspeakers feature a rigid MDF cabinet with internal cross-bracing to prevent any unwanted distortion caused by vibration and resonance.

Wood Veneer Finish: The S20 bookshelf loudspeakers are available in a black or dark oak wood veneer finish.

Removable Grille: The Cambridge Audio S20 bookshelf loudspeakers include removable black cloth grilles.

Magnetically Shielded: The enclosures have been magnetically shielded, so you can safely place the speakers next to your television or computer monitor.

Connections

Binding Posts: The Cambridge Audio S20 bookshelf loudspeakers are equipped with a set of binding post terminals. The binding post terminals will accept bare-wire, pin-connectors, spade-connectors, and banana-plugs (single only).

Color Coded: The terminals are color-coded (black/red) to distinguish between positive and negative.

Mounting Options

Applications: The Cambridge Audio S20 bookshelf loudspeakers are ideal for stereo and home theater applications. You can even add a Cambridge Audio S-series powered subwoofer (779S90B, sold separately).

Placement: Ideally, the bookshelf speakers and listening position should be positioned equal distances apart.

Table-Top Mounting: The Cambridge Audio S20 bookshelf loudspeakers include 8 self-adhesive foam-feet (4 each) to simply place the speakers securely on a desk, table, shelf, or speaker stand securely and safely.

Wall Mounting: The S20 bookshelf loudspeakers can be wall-mounted using the rear-mounted keyhole slot or dual threaded inserts (with optional bracket).

  • Keyhole Slot: The Cambridge Audio S20 bookshelf loudspeakers feature a rear-mounted keyhole slot for mounting the speakers to your walls (screws not included).
  • Dual Threaded Inserts: The S20 bookshelf loudspeakers feature dual rear-mounted M6 threaded inserts that will accommodate an optional articulating wall-mount bracket (sold separately). Two M6 machine screws have to be removed to access the threaded inserts on each speaker.

The Little Beasts

Written by Mike, Technical Support Advisor 4, on 10/10/2012 3:45:00 PM

Recently, I wanted to update my computer speakers. I've tried a few different cheapo 2.1 speaker systems over the past few years; I was ready to spend a little more and get a small, simple system with better dynamic range and frequency response.

The Cambridge S20 speakers are developing an underground reputation as "The Little Beast." They are fairly small bookshelf speakers, only 5 inches wide, 8 inches tall, and 8 inches deep. Despite their small stature, these speakers have impressive bass response. But their primary strength is the clarity and definition in the midrange and high frequencies. Thanks to these "Little Beasts," I can hear details in my music collection I never knew existed.

The only complication from upgrading my speakers if that I now have to re-import my CDs in FLAC format. Due to the increased detail in these S20s, I can really hear the improvement in lossless audio formats. It reminds me of when I bought a high definition television — only then did I appreciate high-resolution video content.I guess I have something to keep me busy this winter.

I highly recommend these speakers. They're a steal at this price.
