Short answer: the Epos ES14N on measured sound quality, the Klipsch RP-600M II on price. The Epos ES14N ranks #19 of 130 bookshelf speakers at $3750. The Klipsch RP-600M II ranks #74 at $449.99, $3300.01 cheaper.
What the Klipsch RP-600M II offers: Redesigned waveguide extends flush to the baffle edge, reducing diffraction compared to the original RP-600M. Roughly 10-20° wider horizontal radiation than the original, giving more soundstage envelopment while retaining precise imaging. A major step up in overall tonal neutrality compared to the original RP-600M, largely eliminating that model’s midrange resonance issues. Unusually, sounds better with the grille on - the grille smooths out the elevated treble rather than degrading the sound, a rare trait among speakers the reviewer has tested. More refined back-panel hardware, including anodized binding posts and jumper cables for optional bi-amping. Responds well to EQ correction (verified using measurement software and a miniDSP), letting the on-axis response be made genuinely linear. Watch for: On-axis, the treble runs notably hot - even hotter than the original RP-600M in some respects - and needs about 20° of toe-out or the grille installed to sound balanced. Horizontal dispersion is very slightly less linear across angles than the original RP-600M, a minor trade-off for the wider overall radiation pattern. Klipsch’s marketed sensitivity (about 94.5dB) is, like the original, a half-space rating roughly 9dB above the anechoic reality (closer to 85-86dB). In-room bass rolls off around 60Hz in practice, and a 120Hz boost paired with a midrange scoop gives kick drums their “tambour” without real low-end weight - a subwoofer is still recommended. Vertical listening tolerance is limited to about ±10° from the tweeter axis. Toeing the speaker out for better on-axis tonality (rather than using the grille) introduces slightly more diffuse imaging from added sidewall reflections.
What the Epos ES14N offers: A revival of Epos’s classic 1980s ES-14, re-engineered by Karl-Heinz Fink’s FinkTeam with a chamfered, backward sloping baffle to time align a 28mm ceramic coated dome tweeter with a 7 inch mica filled polypropylene woofer. On axis deviation measures a clean 0.216dB average and listening window smoothness reaches 0.53, both among the better figures in this batch, and the larger woofer reaches a measured 51.2Hz at -3dB with a low 0.2% THD at 1W. Watch for: The sound power directivity index has the widest standard deviation of any speaker added to this catalog from spinorama.org’s current measurement set, 5.18, meaning off axis energy tracks the on axis response less consistently than the rest of this batch as frequency rises. The bass alignment also measures a higher Q of 1.10, hinting at a mild bump near the port tuning frequency. At £3,750 to £4,400/pair depending on finish it is a serious investment, and dealer availability is limited outside the UK and Canada.
