Whether it’s mounted with the unique isolation options included or even used as a floorstander, with professional installation as part of a Cinergy system, you’ll have world-class cinema sound in your own home. Far superior to your local mainstream cinema, which is normally designed for larger groups to deliver the best median performance for everybody. Cinergy, on the other hand, is a cinema built around you and those closest to you.

* Calculated from a peak voltage, this is not a true power figure but useful for comparisons.

** When used in an In-Wall or On-Wall configuration it is recommended to use the fitted port bungs to control bass output. This will effectively make the product a sealed box.

*** Band limited with Low pass at 200 Hz, should only be used with IA800-2C and the correct speaker profile.

**** Tested with a music like noise signal with distortion and power compression remaining below audible limits.
