Short answer: the Perlisten R5m for better sound quality, the Klipsch RP-600M II for the lower price. The Perlisten R5m ranks #42 of 222 bookshelf speakers, rated 4.3/5, at $6,590. The Klipsch RP-600M II ranks #123, rated 3.7/5, at $449.99, $6,140.01 cheaper.
The case for the Klipsch RP-600M II: Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. The tradeoff: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
The Perlisten R5m is the better-sounding, deeper-bass choice. A large three way bookshelf speaker with dual 6.5 inch woofers, consistent dispersion, and fuller bass than most standmounts. Its bass reaches about 61.7Hz before falling 3dB, against 70Hz for the Klipsch RP-600M II. Watch for: On-axis deviation of 0.264dB and sound-power smoothness of 0.511 are middling, with a fairly pronounced -0.29dB per octave downward tonal tilt and a bass-alignment Q of 2.40 pointing to a somewhat resonant low end.
