Short answer: the Dynaudio Emit 20 for better sound quality, the XTZ Spirit 4 for the lower price. The Dynaudio Emit 20 ranks #133 of 222 bookshelf speakers, rated 3.6/5, at $1,049. The XTZ Spirit 4 ranks #159, rated 3.4/5, at $477, $572 cheaper.
Why pick the XTZ Spirit 4: Stand-mount speakers with a waveguide tweeter, adjustable treble and port tuning, wide coverage and fairly deep bass. The tradeoff: The third-party measurement is low confidence.
The Dynaudio Emit 20 is the deeper-bass option. Bookshelf speakers with unusually deep, low distortion bass for a two-way design and wide, consistent dispersion. Its bass reaches about 33Hz before falling 10dB, against 40Hz for the XTZ Spirit 4. The tradeoff: A resonance around 600-800Hz gives snares and similar percussion a muffled, flat quality lacking impact: confirmed as originating in the woofer itself (isolated via measurements of the raw driver out of the cabinet), and attempts at constrained-layer damping didn’t resolve it.
Buy the XTZ Spirit 4 if the price matters more than sound quality. Buy the Dynaudio Emit 20 if sound quality matters more than the price.
