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 Z906

The Z906 is the only true surround system here, adding 5.1 channels the stereo Klipsch ProMedia 2.1 THX, Logitech Z623, Logitech Z407 and Creative Pebble Plus cannot match, with far more power, though it is overkill for a simple desktop setup and lacks the Z407's Bluetooth.
