Short answer: the Klipsch RP-600M II. It ranks #124 of 223 bookshelf speakers by sound quality, rated 3.7/5, at $449.99; the Philharmonic BMR Monitor ranks #135, rated 3.6/5, and costs $2,200, so there is little reason to consider the other one.
What the Klipsch RP-600M II does well: Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. Watch for: 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 Philharmonic BMR Monitor is the deeper-bass option. Three-way bookshelf speakers with premium drivers, a well-built cabinet and extremely wide dispersion for a broad soundstage. Its bass reaches about 47Hz before falling 3dB, against 70Hz for the Klipsch RP-600M II. The catch: A 1-2dB bump around 2-3kHz creates a “glare” on vocals, guitars, and strings that the reviewer noticed consistently across many tracks.
Buy the Klipsch RP-600M II. It is rated higher for sound quality than the Philharmonic BMR Monitor and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
