The perfect complement to a full SX-series surround sound speaker set, the Cambridge Audio SX70 is the natural choice.
CRISP AND CLEAR SOUND FOR ARTICULATE VOCALS
Featuring a silk dome tweeter, the Cambridge Audio SX70 offers a smooth response that\'s essential for clear, accurate dialogue. Even during intense scenes in action movies, the dialogue can still clearly be heard.
TWIN WOOFERS FOR BROAD STAGING
Using two woofers, placed either side of the tweeter, gives the SX70 a wide soundstage, meaning that it connects up with your front speakers seamlessly. Now, when a jet aircraft rushes across the screen, the sound will follow from left to centre to right without a break.
TOP QUALITY CONSTRUCTION FOR LASTING APPEAL
Made from dense, MDF (Medium Density Fibreboard) rather than flimsy chipboard, the SX70s are built to last. That solid construction also has a knock-on effect in helping to improve the sound quality through higher cabinet rigidity. Other neat design features that we love include the recessed drive units with hidden fixing bolts, making sure the front the panel looks every bit as smooth as the sound.
PART OF THE SX-SERIES AND SO IDEAL FOR SURROUND SOUND SYSTEMS
With floorstanding and standmount sound speakers available, the Cambridge Audio SX70 is ideal as part of a surround sound speaker system. With a similar sonic balance to the other SX-series speakers you get a smooth, uniform sound right the way around your room for a totally enveloping sound.
| Magnetically Shielded |
Are they magnetically shielded? Allows speaker to be placed near a CRT TV/Monitor or sensitive magnetically stored data without the risk of damage. |

| Sensitivity (dB) |
The higher this figure is the easier the speaker is to drive and, hence, requires a less powerful amplifier |
85 |
| Impedance (ohms) |
Resistance. A standard figure is 8ohms |

| Bi-wireable |
Is it bi-wirable? Separate earthing cables for tweeter and woofer units - gives a more precise sound when used with bi-wire cable |

| Speaker Enclosure Type |
Type of speaker enclosure. Infinite baffle cabinets are sealed and so are often less fussy about placement. Usually they do require a little more power to drive, though. Bass reflex speakers are usually more efficient than infinite baffle designs but may require more care in terms of placement. Rear port designs, in particular, usually need at least 15-30cm (6 - 12 inches) between them and the wall behind, for a balanced bass response. ABR = Auxcillary Bass Radiator (looks like a standard bass cone but without power) |
