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 #4 in Best Desktop Computer Speakers

Logitech Z906

4.1

3 sources1 derived$410.99as of Aug 1

The Logitech Z906 is a THX-certified 5.1 surround system with five satellites and a powered subwoofer, putting out 500W RMS. It decodes Dolby Digital and DTS for genuine cinematic surround and fills large rooms with deep bass. Reviewers praise its power and immersion for games and movies, while noting weaker music playback and the lack of HDMI.

Strengths

— True 5.1 surround with five satellites and a powered subwoofer
— THX certified plus Dolby Digital and DTS decoding for cinematic immersion
— 500W RMS (1000W peak) fills large rooms with powerful, room-shaking bass

Watch-outs

— No HDMI inputs, awkward with modern 4K TVs
— No HD-audio (Dolby TrueHD / DTS-HD MA) decoding
— Musical performance is weaker than its cinematic strength

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 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.
