Short answer: the SVS Ultra Evolution Tower. It ranks #112 of 226 floorstanding speakers by sound quality, rated 4.1/5, at $2,998; the MartinLogan Motion F20 ranks #144, rated 3.9/5, and costs $3,039.98, which makes this an easy call rather than a real tradeoff.
The case for the SVS Ultra Evolution Tower: Slim 3-way floorstanding tower with time-aligned curved baffle geometry, a 1-inch diamond-coated aluminum dome tweeter, dual 4.5-inch glass-fiber midranges, and quad force-balanced 5.25-inch woofers. Watch for: 87dB sensitivity is moderate, demanding solid amplification with at least 100W per channel to reach reference home theater volume levels.
What the MartinLogan Motion F20 does well: 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 SVS Ultra Evolution Tower. It is rated higher for sound quality than the MartinLogan Motion F20 and costs less, so only choose the other one for a particular feature it does better.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: SVS Ultra Evolution Tower 3.9 to 4.3; MartinLogan Motion F20 3.7 to 4.1). Treat this verdict as provisional.
