Conditions

* 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.
