Short answer: the Genelec 8320A for better sound quality, the Pioneer DJ VM-50 for the lower price. The Genelec 8320A ranks #9 of 60 powered bookshelf speakers at $850. The Pioneer DJ VM-50 ranks #44 at $169, $681 cheaper.
What the Pioneer DJ VM-50 offers: Compact active monitor with 96kHz DSP, 4mm aluminum front baffle, 5.25-inch aramid woofer and constant-directivity horn. Erin measured F3 at 61Hz, low distortion at 86 and 96dB, almost no long-term compression above 50Hz and only roughly quarter-decibel dynamic nonlinearity. Four-position low- and high-EQ controls yield 16 useful voicings, while balanced TRS/XLR and RCA inputs suit studio and consumer sources. Watch for: The default axial response is not reference-flat and the upper-mid/treble directivity behavior varies with angle; correct EQ-switch selection and listening geometry matter. Bass does not reach 50Hz at reference level despite its pleasing punch, making a subwoofer useful. Output is appropriate for nearfield use rather than home-theater distance. As an internally amplified monitor, passive impedance and sensitivity measurements are not applicable.
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.
