Cambridge SoundWorks offers multiple six-piece surround sound speaker packages. Their entry-level HT55 system is also their most compact, so if you've got very little space with which to set up a 5.1 home theater, you will appreciate the sound you get from the five MC55 satellite speakers which each feature just a single 3½ inch precision driver. Bass is supplied by the BassCube 105 downward-firing 10 inch 75 watt powered subwoofer.

The step-up HT105 package steps up to two-way MC105 satellites with ¾ inch anodized aluminum dome tweeter and 3½ inch midrange.

The HT305 system uses three-driver MC305 speakers with 1 inch aluminum dome tweeter and Neodymium magnet and dual 4 inch molded-composite diaphragm bass/midrange drivers for the front left, center channel, and front right speakers, and a pair of S205 switchable dipole/bipole rear surrounds with 4 inch and 2½ inch full-range drivers within a semi-circular enclosure. The HT305-SE jumps up to the P205 10 inch 200 watt powered sub for much more powerful deep bass response.

The MC630HD speakers each feature a 25mm aluminum dome tweeter and dual 4 inch injection molded copolymer midranges. The tall and slim P300HD 300 watt powered subwoofer uses six high-excursion 6½ inch drivers, three mounted on each side of the enclosure, virtually eliminating distortion from vibrations.

If you want to set up 7.1 surround sound, you will also want to go ahead and purchase two more of the matching satellite speakers.
