Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Morel Avyra 622 ranks #60 of 214 bookshelf speakers by sound quality; the Morel Avyra 633 ranks #48 of 226 floorstanding speakers by sound quality at $2,000.
Why pick the Morel Avyra 622: The standmount in the Morel Avyra 633 family, a 28mm soft dome tweeter and a 160mm woofer rated from 35Hz. Watch for: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers.
Why pick the Morel Avyra 633: A 2.5-way floorstanding tower with two 6” mid-woofers (each with an unusually large 3” voice coil for better power handling) and a dome tweeter; the bottom woofer only covers up to about 250Hz while the top woofer runs all the way to the 2.2kHz crossover point. The tradeoff: 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 Morel Avyra 622 if you want a bookshelf speaker. Buy the Morel Avyra 633 if you want a floorstanding speaker instead.
About the ratings: the Morel Avyra 622’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 3.9 to 4.5, so this verdict could change once it is measured.

The Two Speakers In Full
Morel Avyra 622 Estimated eBay
Same family: the Morel Avyra 633 (floorstanding, rated 4.4/5) and the Morel Avyra C5 (center, estimated 4/5).
Pros: The standmount in the Morel Avyra 633 family, a 28mm soft dome tweeter and a 160mm woofer rated from 35Hz. The Ear found clean tonal balance, detailed treble, a strong midrange and convincing bass for its size.
Cons: No independent measurements yet, so its tonal balance and directivity can’t be compared with ranked speakers. It is sold through dealers with no listed US retailer, and it needs good stands.

Morel Avyra 633: $2,000 per pair eBay
Same family: the Morel Avyra 622 (bookshelf, estimated 4.2/5) and the Morel Avyra C5 (center, estimated 4/5).
Pros: A 2.5-way floorstanding tower with two 6” mid-woofers (each with an unusually large 3” voice coil for better power handling) and a dome tweeter; the bottom woofer only covers up to about 250Hz while the top woofer runs all the way to the 2.2kHz crossover point. Easy to drive at a nominal 4 ohms (minimum 3.8 ohms). On-axis linearity measures within about ±2.25dB: genuinely impressive for a tower in this class, enough that the reviewer said he’d have guessed a $4,000-5,000 per pair price just from the look and the data alone. F3 of about 50Hz and F10 of about 32Hz give reasonable kick-drum-level bass without a subwoofer. Wide horizontal radiation around ±70° with good continuity outside the treble region. Harmonic distortion stays under 1% THD to about 100Hz at both 86dB and 96dB, and using an 80Hz subwoofer crossover barely changes midrange distortion: a sign the drive units themselves are good quality rather than excursion-limited. About 20dB of usable dynamic range. No through-holes for spikes, so no risk of dropped hardware during setup. Measured bass extension of 50Hz (-3dB), with a measured sensitivity of 86.5dB.
Cons: 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. Best aimed directly at the listener rather than toed out, since the top end already rolls off a little at wider angles. Imaging loses a bit of precision specifically in that lower-treble region. Multitone distortion exceeds the reviewer’s 3% comfort threshold at higher output. Real bass extension below 50Hz still needs a subwoofer. Not the same speaker as the Parts Express “Solstice” DIY kit despite surface similarities: different tweeter, different (ported vs. transmission line) enclosure, and measurably different woofers.
