Short answer: the Dynaudio LYD 5. It ranks #6 of 108 powered bookshelf speakers by sound quality (rated 4.5/5) at $998 and is still sold new; the Devialet Phantom II 98 dB ranks #11 (rated 4.4/5) and is discontinued, so it is only an option used. The Devialet Phantom II 98 dB’s replacement, the Devialet Phantom Ultimate 98dB, is rated 4.4/5 at $3,998.
The Devialet Phantom II 98 dB is the deeper-bass choice. A compact wireless streaming speaker with startlingly deep bass for its size and an even, well balanced sound. Its bass reaches about 30Hz before falling 3dB, against 68Hz for the Dynaudio LYD 5. Watch for: Small-enclosure bass extension at the measurement level does not guarantee the same response at high volume.
Why pick the Dynaudio LYD 5: An affordable studio monitor with highly accurate, uncolored midrange, especially strong when paired with a subwoofer. The tradeoff: Bass reaches -3dB around 72Hz, so it gives up low-frequency weight to deeper-reaching monitors.
Buy the Dynaudio LYD 5. It is rated higher for sound quality; the Devialet Phantom II 98 dB is no longer sold new.
