Short answer: the Philharmonic BMR Monitor for better sound quality, the KEF Q3 Meta for the lower price. The Philharmonic BMR (v1) ranks higher than the KEF Q3 Meta (#40 vs #156 of 222 bookshelf speakers) but is discontinued. Its replacement, the Philharmonic BMR Monitor, is rated 3.6/5 at $2,200; the KEF Q3 Meta is rated 3.4/5 at $764.97, $1,435.03 cheaper.
The KEF Q3 Meta is the deeper-bass option. Coaxial bookshelf speakers with very wide dispersion, punchy kick drums and bass tuning that works close to a wall. Its bass reaches about 52Hz before falling 3dB, against 62Hz for the Philharmonic BMR (v1). Watch for: Not well suited to high-output use: compression and strain in the 1-2kHz region emerge above about 90dB at 10 feet, so a high-output home theater setup isn’t the best application.
The Philharmonic BMR (v1) is the better-sounding pick. A large three way bookshelf speaker with a ribbon tweeter, flat response, broad coverage, and an unusually expansive midrange. The catch: The measured 83dB sensitivity and roughly 4-ohm load demand meaningful external amplification.
Buy the KEF Q3 Meta if price matters most. For better sound quality, the Philharmonic BMR Monitor, the replacement for the discontinued Philharmonic BMR (v1), is rated higher but costs $2,200.
