Our recommendation
Buy the Logitech Z623 if maximum bass depth and power matter most, since its subwoofer is the stronger of the two. Buy the Klipsch ProMedia 2.1 if dialogue clarity and a desk control pod matter more, since its horn tweeters keep voices intelligible in busy scenes. Both are THX-certified 2.1 systems with long track records; the choice is about character, not quality.
Bass character
The Z623 subwoofer digs deeper and plays louder, which suits action films and bass-heavy games. The Klipsch subwoofer is tighter and more controlled, which suits music and dialogue-led films. Neither is boomy when set sensibly, but the Logitech system is the one to choose when bass impact is the priority.
Dialogue and detail
The Klipsch horn tweeters give voices and effects an edge in clarity that the Logitech satellites, good as they are, do not quite match. In a busy film scene, Klipsch dialogue stays forward and intelligible, while the Logitech presentation is warmer and slightly more blended. Treble-sensitive listeners may actually prefer the Logitech warmth.
Controls
The Klipsch control pod is the more convenient controller, with volume, subwoofer level, and a headphone jack in a small desk unit. The Logitech controls sit on the right satellite, which is nearly as convenient but ties control placement to speaker placement. Both beat rear-panel controls, and neither system offers a remote.
Choose Logitech Z623 if…
- You want the deepest, most powerful bass
- You play action games and watch blockbuster films
- You prefer a warmer, more blended sound
Choose Klipsch ProMedia 2.1 if…
- Dialogue clarity is your top priority
- You want a dedicated desk control pod
- You prefer a livelier, more detailed treble

Strengths and limitations
Logitech Z623
Strengths
- THX certification means the system is tuned to a recognised standard rather than boosted for showroom effect, so films sound balanced at both low and high volume.
- The subwoofer gives action scenes and game soundtracks a weight that no compact 2.0 pair can reproduce, while the satellites stay clear on dialogue.
- Volume, bass, and power sit on the right satellite, with a headphone jack beside them, so late-night listening needs no reach behind the desk.
Limitations
- Wired inputs only, so a phone connects by cable, and there is no Bluetooth for quick wireless listening.
- The subwoofer is large and heavy for a small room, and it needs floor space that a compact desk setup may not have.
- The styling is functional rather than handsome, and the satellites look like computer speakers rather than furniture.
Klipsch ProMedia 2.1
Strengths
- The horn-loaded tweeters give dialogue and effects unusual clarity for a desk system, so voices stay intelligible even during busy scenes.
- The subwoofer adds genuine weight to films and games without muddying the satellites, and its level is adjustable from the control pod.
- The control pod puts volume, subwoofer level, and a headphone jack on the desk, which is more convenient than rear-panel controls.
Limitations
- The lively tuning can sound bright on already bright recordings, and treble-sensitive listeners may prefer the warmer Edifier pairs here.
- There is no Bluetooth and no remote, so every adjustment means reaching for the control pod.
- The satellites and subwoofer need more desk and floor space than a compact 2.0 pair, which rules out the smallest setups.

Made your call?
Questions, answered
Which is better for music?
The Klipsch, slightly, for vocal and acoustic music, thanks to its horn clarity. The Logitech suits bass-heavy and electronic music better, where its deeper subwoofer carries the track. Both handle general music well, so genre tips the choice.
Do both need floor space for a subwoofer?
Yes, both are 2.1 systems with a separate subwoofer that belongs on the floor. Neither subwoofer should sit on the desk, and both need a little clearance from walls to avoid boomy bass.
Which is easier to set up?
Both are equally simple: connect the satellites and subwoofer, plug in power, and connect one cable to the computer. The Klipsch control pod adds one small desk unit to place, while the Logitech system keeps controls on the satellite.
