Short answer: the Devialet Phantom Ultimate 98dB, if you are buying new. The Devialet Phantom II 98 dB ranks higher than the IK Multimedia iLoud MTM MKII (#10 vs #22 of 100 powered bookshelf speakers) but is discontinued; its replacement, the Devialet Phantom Ultimate 98dB, is rated 4.4/5 at $3,998 and is still sold new.
Why pick the IK Multimedia iLoud MTM MKII: Erin’s MKII measurements give a 2.2dB midrange span, a -3dB point around 53Hz, and preference scores of 5.22 standalone and 7.44 with an ideal subwoofer. The tradeoff: Some excess treble remains in the native tuning.
The Devialet Phantom II 98 dB is the more accurate, deeper-bass option. The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Its measured preference score, a predictor of how neutral it sounds, is 6.87 against 5.22 for the IK Multimedia iLoud MTM MKII. Its bass reaches about 30Hz before falling 3dB, against 52.7Hz for the IK Multimedia iLoud MTM MKII. The tradeoff: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.

IK Multimedia iLoud MTM MKII: $699.99 per pair Amazon eBay
Older model: the IK Multimedia iLoud MTM (ranked lower, rated 4.1/5).
Same family: the IK Multimedia iLoud Micro Monitor Pro (smaller bookshelf, estimated 4.3/5).
Pros: Erin’s MKII measurements give a 2.2dB midrange span, a -3dB point around 53Hz, and preference scores of 5.22 standalone and 7.44 with an ideal subwoofer. The compact layout and included calibration microphone suit a close desktop setup. Existing tests show useful room-peak correction and good harmonic-distortion behavior at moderate levels. Measured bass extension of 52.7Hz (-3dB).
Cons: Some excess treble remains in the native tuning. The two-woofer MTM arrangement narrows the vertical listening window, so ear height and orientation matter. Multitone distortion rises strongly when pushed toward 96dB/1m; the review favors moderate listening levels, and a subwoofer does not eliminate all midrange output limits. These are MKII results, not measurements of the original MTM. Treble runs about 3dB hot on-axis; the rear -3dB treble switch overcorrects, and about -1.5dB of external EQ works better.

Devialet Phantom II 98 dB: $2,998 per pair Discontinued Devialet eBay
Newer model: the Devialet Phantom Ultimate 98dB, ranked lower, estimated 4.4/5.
Pros: The manufacturer-supplied measurement shows unusually deep bass for the enclosure size: -3dB at 30Hz. Scores of 6.87 standalone and 7.95 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. Measured bass extension of 30Hz (-3dB).
Cons: 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. Discontinued.
