How they stack up

Klipsch ProMedia 2.1 THX

The ProMedia 2.1 THX offers cleaner, more detailed highs than the Logitech Z623 thanks to its horn tweeters and MDF cabinets, and far stronger sound quality than the budget Creative Pebble Plus, though it lacks the Bluetooth of the Logitech Z407 and the surround channels of the Logitech Z906.

Logitech Z623

The Z623 puts out more raw RMS power (200W) than the Klipsch ProMedia 2.1 THX and has more inputs, but its plastic satellites lack the detail of the Klipsch horn tweeters, and it has no Bluetooth like the Logitech Z407 or surround channels like the Logitech Z906.
