Short answer: the Genelec 8320A for better sound quality, the NHT Pro M-00 for the lower price. The Genelec 8320A ranks #9 of 64 powered bookshelf speakers at $850. The NHT Pro M-00 ranks #64 at $498, $352 cheaper.
What the Genelec 8320A offers: The Directivity Control Waveguide and die cast aluminum Minimum Diffraction Enclosure produce a listening window smoothness score of 0.53 and a low frequency alignment Q of just 0.227, the cleanest, least resonant bass rolloff of any speaker in this whole batch. It network calibrates through Genelec’s GLM software for automatic room correction, and Intelligent Signal Sensing drops standby power to under 0.5W. Watch for: On axis deviation measures 0.169dB average, decent but not class leading next to the AsciLab and Audio Smile entries in this batch. The compact 4.1 inch woofer limits low frequency extension to a measured 67.4Hz at -3dB, so a subwoofer is needed for full range use. The GLM calibration kit that unlocks its room correction features is sold separately from the speaker price, and max SPL tops out around 100dB, modest next to Genelec’s larger 8000 series monitors.
What the NHT Pro M-00 offers: Cast aluminum-zinc alloy enclosure doubles as a heatsink for the built-in discrete Class AB amplifier, and both RCA and XLR/TRS inputs are provided with a near-field/far-field voicing switch. Watch for: Amir identified a critical flaw: a sudden suck-out in the upper bass frequencies that affects many commonly-used notes. Treble peaks on-axis, and vertical-axis performance is particularly problematic. In-room response turns notably bright in rooms with absorptive surfaces. Comparing directly to the JBL 305P Mark II, Amir found the NHT sounded “dead and bright” while the JBL was “balanced” with “rich and warm detail,” concluding, “I would not remotely use the NHT M-00 relative to JBL 305P Mark ii. The difference in overall fidelity and pleasantness is immense.” Long discontinued; not recommended even on the used market.
Buy the Genelec 8320A if sound quality matters more than the price. Buy the NHT Pro M-00 if the price matters more than sound quality.
If sound quality matters at all to you, skip the NHT Pro M-00. It ranks near the bottom of the 64 powered bookshelf speakers, so look higher up the list instead.
