Klipsch ProMedia 2.1 THX

4.3

3 sources2 derived$199.99as of Aug 1

The Klipsch ProMedia 2.1 THX is the best-sounding 2.1 desktop speaker system for the money, leading with big, room-filling bass and horn-loaded satellites that stay crisp and clear even at very high volume. THX certification and a measured 95 dB output with no distortion make it a powerhouse for gaming, movies and music. The trade-offs are its lack of Bluetooth and its dated, space-hungry design, but on pure sound-per-dollar it's a long-running classic.

Strengths

— Big, room-filling bass from a powerful 130W-rated subwoofer
— Gets extremely loud – around 95 dB measured – with no distortion
— THX certification and a wide, detailed soundstage from horn-loaded satellites

Watch-outs

— No Bluetooth or wireless connectivity, analog inputs only
— Dated design and no remote or app control
— The subwoofer needs floor space and the satellites are large

Ranked #5 in Best Desktop Computer Speakers

Logitech Z623

4.0

3 sources1 derived$184.99as of Aug 1

The Logitech Z623 is a THX-certified 2.1 system delivering 200W RMS with an immensely powerful side-ported subwoofer. Reviewers praise its deep, rich bass and value for games and movies, while noting the satellites lack high-end detail. With two 3.5mm inputs plus RCA, it connects three devices at once, making it a flexible, bass-forward desktop choice.

Strengths

— THX-certified 2.1 system with 200W RMS, one of few PC sets to earn THX
— Powerful side-ported subwoofer delivers deep, rich bass and real low-end rumble
— Multiple inputs (two 3.5mm plus RCA) connect three devices at once

Watch-outs

— Satellites lack high-end detail; treble can sound rolled off
— All-plastic construction is more resonance-prone than MDF rivals
— No Bluetooth connectivity

How they stack up

Klipsch ProMedia 2.1 THX

The Klipsch ProMedia 2.1 is the bass and volume king of this group, with a far more powerful subwoofer and higher output than the Logitech Z407, Creative Pebble X Plus or the sub-less Audioengine A2+ Wireless and Edifier R1280T. The trade-off is connectivity: where the Logitech Z407 and Audioengine A2+ Wireless add Bluetooth, the Klipsch is analog-only, betting everything on sound rather than convenience.

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.
