Short answer: the Devialet Phantom II 98 dB on measured sound quality, the Focal Alpha 50 EVO on price. The Devialet Phantom II 98 dB ranks #9 of 65 powered bookshelf speakers at $2998. The Focal Alpha 50 EVO ranks #36 at $329, $2669 cheaper.
What the Focal Alpha 50 EVO offers: Rear shelving controls and a conventional studio-monitor layout provide practical placement adjustment. Watch for: Basic shelving controls are less flexible than parametric room correction. Careful placement is still important, especially near walls or on a desk.
What the Devialet Phantom II 98 dB offers: The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Scores of 6.07 standalone and 7.15 with an ideal subwoofer suggest that its appeal is not limited to bass quantity. Integrated amplification and network playback can replace several components, and its 2.3dB midrange response span is reasonably even. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume. Stereo requires two units, and the integrated architecture offers less system flexibility than conventional monitors.
