How they stack up

Creative Pebble Plus

The Pebble Plus is far smaller, cheaper and quieter than the Klipsch ProMedia 2.1 THX, Logitech Z623 and Logitech Z906, and lower-powered than the Logitech Z407, but its USB-powered convenience and dedicated subwoofer make it the best ultra-budget 2.1 pick here.

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.
