Short answer: the Dynaudio Emit 30. Both are rated 3.9/5 for sound quality (#139 and #144 of 226 floorstanding speakers), and the Dynaudio Emit 30 costs $1,274.25 against $3,039.98 for the MartinLogan Motion F20, so with nothing between them on sound quality, price settles it.
The case for the Dynaudio Emit 30: A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. Watch for: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven (sometimes soft, sometimes forward) depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result.
The case for 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 Dynaudio Emit 30. Both are rated the same for sound quality, and it costs $1,765.73 less than the MartinLogan Motion F20.
About the ratings: the MartinLogan Motion F20’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.7 to 4.1, so this verdict could change once it is measured.

The Two Speakers In Full
Dynaudio Emit 30: $1,274.25 per pair Amazon eBay
Same family: the Dynaudio Emit 10 (smaller bookshelf, estimated 3.2/5), the Dynaudio Emit 20 (larger bookshelf, rated 3.6/5), the Dynaudio Emit 50 (larger floorstanding, ranked higher, estimated 4.2/5) and the Dynaudio Emit 25C (center, estimated 3.7/5). See every Dynaudio Emit generation.
Pros: A 2.5-way floorstander: two 5.25” mid-woofers paired with a roughly 1” dome tweeter, driven through dual rear bass-reflex ports. The two woofers hand off at staggered crossover points (around 1kHz and 3.5kHz) rather than sharing one, which avoids the acoustic lobing a shared crossover point would cause between the tweeter and the lower woofer, and adds a few dB of sensitivity in the process. Genuinely deep bass for a speaker around this price: measured F3 near 44Hz and extends audibly down to about 40Hz in-room without much difficulty. Harmonic distortion measures clean and low at both 86dB and 96dB SPL/1m. Good CTA-2034 sound power and uniform directivity mean the speaker takes EQ correction well if a listener wants to dial in its one tonal weak point. Dynamic range and compression performance are strong overall, with only a minor, high-Q compression artifact tied to a cone-edge resonance that’s unlikely to be audible. Wide, consistent horizontal dispersion around ±70° with just a small ~10° narrowing between 1-3kHz, and a reasonably forgiving ±20° vertical window centered on the tweeter axis. Measured bass extension of 44Hz (-3dB).
Cons: A dip and inconsistency in the lower-treble presence region (roughly 2-5kHz) makes the top end sound uneven (sometimes soft, sometimes forward) depending on the specific instrument or frequency being reproduced; male vocals can lack presence and cymbals can lack sizzle as a result. A cone-edge surround resonance shows up around 1-1.3kHz in burst-decay measurements (a trait the reviewer has also seen on other Dynaudio models) and lines up with elevated multitone distortion across roughly 600Hz-1.5kHz. An enclosure resonance appears around 350Hz in the impedance curve. Placed too close to a rear wall, the dual ports make the bass noticeably boomy: pulling the speaker out is needed to keep the low end from overloading the room. Fully resolving the top-end inconsistency needs a modest EQ correction (roughly +2dB with a Q of about 1, centered 3-6kHz), so out-of-the-box tonal accuracy in that band isn’t quite class-leading despite otherwise strong measured performance.

MartinLogan Motion F20: $3,039.98 per pair Estimated Audio Advice eBay
Same family: the MartinLogan Motion B10 (bookshelf, rated 3.6/5), the MartinLogan Motion F10 (smaller floorstanding, ranked lower, estimated 3.8/5), the MartinLogan Motion C10 (center, estimated 3.7/5) and the MartinLogan Motion MP10 (surround, estimated 3.5/5).
Pros: Larger 6.5-inch dual aluminum woofers provide greater bass depth down to 35Hz and increased dynamic headroom for larger rooms. Wide horizontal dispersion and crisp transient response from the Gen2 Folded Motion tweeter.
Cons: Noticeable treble energy elevation requires careful acoustic matching or gentle toe-in. Substantial physical footprint and height.
