Impressively punchy performance

Experience the crisp treble, surprisingly deep bass, and extraordinary soundstage that Cambridge Audio's SX-50 speakers deliver. You'll be amazed that these compact bookshelf speakers have the power to make your favorite concerts, movies, and sports come to life. They're ideal for home theater or stereo setups in small-to-medium-sized rooms, or as hi-fi desktop computer speakers. Just add the matching SX-120 powered subwoofer and listen to these babies really sing!

Carefully engineered drivers for musical sound

Unlike some compact speakers which can sound shrill or fatiguing, each SX-50 uses a 1" silk soft dome tweeter for smooth, detailed highs. The tweeter's foam damper helps reduce reflections and increase soundstage depth for a truly spacious, room-filling experience. The 5-1/4" custom designed mid/woofer delivers accurate midrange and powerful, yet controlled bass with minimal distortion.

The SX-50's solidly braced MDF cabinets are computer-designed to help minimize standing waves and prevent unwanted resonance from coloring the sound. Heavy-duty, gold-plated binding posts make it easy to connect the high-quality speaker wire of your choice for top-notch performance.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Features

1" Silk Dome Tweeter: The Cambridge Audio SX-50 bookshelf loudspeakers feature a silk dome tweeter that combines a soft, smooth sound with high levels of detail. A dedicated foam damper behind the tweeter reduces reflections and increases sound stage depth for a truly spacious, room-filling experience where you can pick out every instrument.

5.25" Treated Paper Cone Woofer: The SX-50 bookshelf speakers employ a custom-designed 5.25" midbass driver with a treated paper cone for a smooth and even frequency response. High power, efficient woofer magnets deliver deep bass without putting stress on your amp.

Optimized Crossover Network: The SX-50 uses a precisely optimized crossover between the woofer and tweeter that gives the smoothest and most linear response.

Rigid Bass Reflex Enclosure: The Cambridge Audio SX-50 bookshelf speakers feature a rigid MDF cabinet, expert designed to minimize standing waves and deliver deeper, tighter bass response. The enclosure features rear-firing port for improved efficiency and bigger bass output.

Binding Posts: The Cambridge Audio SX-50 bookshelf loudspeakers are equipped with a set of binding post terminals. The binding post terminals will accept bare-wire (up to 10AWG), pin-connectors, spade-connectors, and banana-plugs (dual or single). The terminals are color-coded (black/red) to distinguish between positive and negative.

Applications: The Cambridge Audio SX-50 bookshelf loudspeakers are ideal for stereo and home theater applications in smaller rooms. You can even add a Cambridge Audio SX-series powered subwoofer (779SX120, sold separately).

Placement: Ideally the speakers and listening position should be located equal distances apart. The speakers should also be placed at ear level. In addition, the speaker should be positioned at least 2" away from the back wall. If the speakers are placed on a desk or close to a wall, the bass may become too strong. The included foam inserts will reduce the bass output when inserted into the speakers' ports.

Mounting Options: The Cambridge Audio SX-50 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. The foam feet add approximately 0.125" to the height of the speakers. The optional PinPoint heavy duty side-grip wall-mounting bracket (121AM40B, sold separately) can be used to wall mount the speakers.

Little box, BIG sound

Written By Klaus, Dallas, TX on Wednesday, November 12, 2014

Crutchfield Customer Review (What's this?)

My wife wanted small and unobtrusive, and I (being a musician as well as a typical dude) wanted a big, pure, and loud-capable sound. Well, I found the perfect speakers. These things create a wonderful, full soundscape, from Bartok's string quartets to AC/DC's rock. I actually hang my speakers (these included) in the upper corners of my living room facing down and towards the opposite wall, basically where the couch is. I'm not a sound engineer, but you don't really have to be if you listen to your ears and experiment a bit. We are both very happy.

Pros: Visually - small and aesthetically pleasing; Sound - big and aesthetically pleasing

Cons: none, for our application

Great speakers, good bass

Just as expected

Written By Michael, Glendale, CA on Thursday, August 07, 2014

Crutchfield Customer Review (What's this?)

I bought these speakers knowing they weren't top of line thousand dollar speakers but would definitely be an upgrade over my 2.5" L/R especially when it came to music and that is exactly what I got. Very few professional reviews out there for them since they are fairly new but read enough to know they would be worth every penny plus more! They sound great and can go down pretty low for the price. Good detail and sound and they stay composed at high volume. They have a very flat sound to them so music sounds beautiful but takes a bit getting used to for movies but in the end I am very satisfied and couldn't ask for much more.

Pros: Look beautiful. Very natural and flat. Good detail. Good bass detail. Good price.

Cons: No magnetic grill covers.

Good for the money

Written By Dave, Central NJ on Tuesday, July 29, 2014

Crutchfield Customer Review (What's this?)

Great sound in a small package. You can adjust the base response by fiddling with the placement and by using or removing the foam included foam baffles that go in the rear ports. Base can be loud and boomy if you want it, or more subtle, which is what I prefer. Vocals sound fantastic. Highs are a little lacking, but I'm comparing them to my KEF speakers that cost 5 times as much. I turned up the treble and they sound fine.

The speakers also come with small plastic feet you can put on them to protect the finish. Mine are placed on the floor.

Pros: Very nice sound for the money. Base can be adjusted by placement.

Cons: Sensitive to placement. I've deliberately listed this as both a pro and a con. High end isn't fantastic, but you get what you pay for.
