Our recommendation
Buy the Klipsch RP-600M II if dynamics, punch, and high volume matter most, and your room can handle a forward treble. Buy the Polk ES20 if versatility matters most: a pair that serves films and music equally, mounts on a wall, and expands into a surround system with ease. Both suit home theatre; the Klipsch thrills, the Polk accommodates.
Dynamics against balance
The Klipsch horn delivers explosive dynamics and a direct, present sound that makes action films feel large. The Polk delivers a more even, balanced presentation that suits dialogue, music, and long sessions without fatigue. The Klipsch wins the loud moments, the Polk wins the long evening.
Efficiency and amplifier needs
The Klipsch plays loud from a modest receiver, thanks to horn efficiency, which frees budget for a subwoofer or centre speaker. The Polk needs a little more amplifier to reach the same volume, but remains easy to drive by normal receiver standards. Neither pair demands an exotic amplifier.
Placement and expansion
The Polk offers keyhole wall mounting and a natural place inside a Polk surround family, which simplifies building a full system. The Klipsch needs stands or a deep shelf, and its larger cabinets demand more room. For a wall-mounted surround setup, the Polk is the practical choice.
Choose Klipsch RP-600M II if…

- You love an energetic, forward presentation
Choose Polk Audio Signature Elite ES20 if…
- You want one pair for films and music equally
- You plan wall mounting or a full surround system

Strengths and limitations
Klipsch RP-600M II
Strengths
- The hybrid Tractrix horn makes the tweeter highly efficient, so even a modest amplifier drives these speakers to room-filling volume with headroom to spare.
- The Cerametallic woofer delivers punchy, articulate bass that suits drums, explosions, and action soundtracks without needing a subwoofer for every scene.
- Dynamics are the headline: quiet passages stay quiet and loud passages hit hard, which is exactly what film soundtracks and live recordings need.
Limitations
- The forward, energetic treble can feel too bright in a hard, reflective room, and it shows up harsh recordings rather than smoothing them over.
- The cabinets are larger and heavier than they look in photos, so check shelf depth and stand capacity before ordering.
- The ebony vinyl finish is smart but plain, and buyers wanting furniture-grade wood will find the look more functional than decorative.
Polk Audio Signature Elite ES20
Strengths
- The Power Port design smooths airflow from the rear port, which keeps bass deeper and cleaner than a plain ported cabinet at the same size.
- The Terylene tweeter reaches into hi-res territory, giving cymbals and dialogue air without the harsh edge cheaper tweeters add.
- Keyhole slots and a magnetic grille make wall mounting and living room placement straightforward, and the pair slots neatly into a Polk surround setup.
Limitations
- The cabinet is deeper than average, so a shallow bookshelf may leave the rear port too close to the wall for best bass.
- Voices and midrange are clear rather than lush, which suits films and pop but may leave some acoustic recordings feeling a touch lean.
- The styling is modern and understated, which some buyers will call clean and others will call plain next to walnut rivals.

Questions, answered
Which is better for dialogue?
Both handle dialogue well, in different ways. The Klipsch horn makes voices direct and present, cutting through a busy room, while the Polk presents dialogue clearly within a balanced mix. In a quiet room the difference is small; in a noisy living room the Klipsch edge shows.
Which needs a subwoofer more?
Both benefit from a subwoofer for films, but the Klipsch bass punch reduces the urgency, while the Polk deeper Power Port bass also holds up well alone. For action films at high volume, add a subwoofer to either pair.
Can either pair work for music too?
Yes. The Klipsch suits rock and pop with energy to spare, while the Polk suits a wider range of genres with its balanced presentation. Music-first buyers who also watch films should lean Polk; film-first buyers should lean Klipsch.
