Short answer: the Arendal 1961 Tower. Both are rated 4.4/5 for sound quality (#47 and #48 of 228 floorstanding speakers), and the Arendal 1961 Tower costs $1,900 against $2,000 for the Morel Avyra 633, so with nothing between them on sound quality, price settles it.
Why pick the Arendal 1961 Tower: Slim sealed towers with accurate sound and exceptionally clean output at high volume, a great home theater front pair with a subwoofer. The tradeoff: Erin measured F3 at 62Hz and F10 at 43Hz, so the four woofers prioritize clean output over deep extension; a subwoofer remains necessary.
The Morel Avyra 633 is the more accurate, deeper-bass choice. Floorstanding speakers with impressively even, accurate sound, wide dispersion, kick drum bass without a subwoofer and an easy load to drive. Its measured preference score, a predictor of how neutral it sounds, is 5.43 against 4.83 for the Arendal 1961 Tower. Its bass reaches about 50Hz before falling 3dB, against 62Hz for the Arendal 1961 Tower. Watch for: A bit bright out of the box: extra tweeter energy in the 4-7kHz region (which also shows up as nonlinearity in the early-reflections directivity data, making it harder to fully correct with EQ) reflects off nearby sidewalls and can sound tipped-up or edgy; a single EQ band (about 4.4kHz, -2dB, Q of 1) or absorption panels placed 60-80° off-axis on the sidewalls resolves it.
Buy the Arendal 1961 Tower. Both are rated the same for sound quality, and it costs $100 less than the Morel Avyra 633.
