Short answer: the Klipsch ProMedia 2.1 THX. It ranks #2 of 8 powered subwoofer and satellite combo speakers by sound quality, rated 3.4/5, at $167.49; the Harman Kardon SoundSticks 4 ranks #3, rated 3.3/5, and costs $229.95, so there is not much of a tradeoff to weigh.
What the Klipsch ProMedia 2.1 THX does well: The long-standing benchmark in high-output 2.1 multimedia audio, delivering 200W continuous / 260W peak power across a 6.5-inch side-firing ported subwoofer and dual two-way horn-loaded satellites. The catch: The tonal signature exhibits Klipsch’s characteristic forward treble elevation that can sound bright on poorly recorded material without EQ.
The case for the Harman Kardon SoundSticks 4: An iconic sculptural design featuring clear transparent domes that showcase the inner acoustic architecture and subtle LED lighting. The catch: The transparent acrylic surfaces readily show dust, fingerprints, and micro-scratches requiring regular care.
Buy the Klipsch ProMedia 2.1 THX. It is rated higher for sound quality than the Harman Kardon SoundSticks 4 and costs less, so only choose the other one for a particular feature it does better.

The Two Speakers In Full
Klipsch ProMedia 2.1 THX: $167.49 Amazon eBay
Pros: The long-standing benchmark in high-output 2.1 multimedia audio, delivering 200W continuous / 260W peak power across a 6.5-inch side-firing ported subwoofer and dual two-way horn-loaded satellites. Klipsch’s 90 x 40 MicroTractrix horns deliver energetic, dynamic highs and exceptional dialogue clarity, while the dedicated subwoofer delivers authoritative desktop bass punch down to approximately 40Hz with THX certification headroom. Simple plug-and-play 3.5mm analog connection makes it universally compatible with PCs, monitors, gaming consoles, and DACs.
Cons: The tonal signature exhibits Klipsch’s characteristic forward treble elevation that can sound bright on poorly recorded material without EQ. The proprietary control pod cable and hardwired satellite wiring can be vulnerable to wear over long-term use. No digital optical or USB inputs.

Harman Kardon SoundSticks 4: $229.95 Amazon eBay
Pros: An iconic sculptural design featuring clear transparent domes that showcase the inner acoustic architecture and subtle LED lighting. Powered by a robust 140W RMS total amplifier, the system pairs a 5.25-inch down-firing subwoofer with dual vertical satellite columns housing four 1.4-inch full-range transducers each. The vertical transducer array produces a focused, wide stereo soundstage with clear vocal projection and tight, musical bass reaching down to 40Hz. Supports Bluetooth 4.2 wireless streaming alongside standard 3.5mm aux input.
Cons: The transparent acrylic surfaces readily show dust, fingerprints, and micro-scratches requiring regular care. There is no USB audio or optical input, and tone controls are minimal with no separate treble adjustment on the unit. Satellite cables are permanently attached to the sub.
