At a glance the specifications are in the ball park of where we would suspect them to be at this price point, with the subwoofer receiving a healthy 116-watts RMS and the sats all receiving different amounts of power ranging from 38 to 42-watts.

Total peak power is rated at 630-watts but the RMS figure is the one to watch for, peak power or "peak music power" is just for show.

Logitech being the heavyweight that they are have said "I’ll show you!" and put the RMS and PMP figures directly next to each other on the front of the box. Top marks for detail like that!

Frequency response is about on par with what would be expected from a system not using a subwoofer driver of any considerable stance yet is still very respectable and well capable of providing an immersive experience.
