Short answer: the DALI Sonik 5. Both are rated 3.9/5 for sound quality (#148 and #144 of 226 floorstanding speakers), and the DALI Sonik 5 costs $1,800 against $3,039.98 for the MartinLogan Motion F20, so with nothing between them on sound quality, price settles it.
The case for the DALI Sonik 5: A slim tower with two 5.25” woofers and the 29mm tweeter of the DALI Sonik 1, rated from 39Hz. The tradeoff: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the MartinLogan Motion F20: Larger 6.5-inch dual aluminum woofers provide greater bass depth down to 35Hz and increased dynamic headroom for larger rooms. The catch: Noticeable treble energy elevation requires careful acoustic matching or gentle toe-in.
Buy the DALI Sonik 5. Both are rated the same for sound quality, and it costs $1,239.98 less than the MartinLogan Motion F20.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: DALI Sonik 5 3.6 to 4.2; MartinLogan Motion F20 3.7 to 4.1). Treat this verdict as provisional.
