Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Sonus Faber Lumina III ranks #118 of 139 floorstanding speakers by sound quality at $2,399; the Sonus Faber Lumina I ranks #69 of 122 bookshelf speakers by sound quality at $900.
Why pick the Sonus Faber Lumina III: Slim 3-way floorstanding tower with dedicated 4.7-inch midrange and dual 4.7-inch bass drivers extending reach to 40Hz. Watch for: Small 4.7-inch bass drivers limit maximum deep-bass slam and high-SPL output compared to larger-woofer floorstanders.
Why pick the Sonus Faber Lumina I: Handcrafted Italian cabinet with multilayer real-wood front baffle and leather-wrapped enclosure. The tradeoff: Low sensitivity of 84dB demands substantial amplifier power to reach moderate volumes.
Buy the Sonus Faber Lumina III at $2,399 if you want a floorstanding speaker. Buy the Sonus Faber Lumina I at $900 if you want a bookshelf speaker instead.

Sonus Faber Lumina III: $2,399.00 per pair Estimated Crutchfield eBay
Smaller models: the Sonus Faber Lumina II (rated 3.4/5) and the Sonus Faber Lumina I (estimated 3.3/5).
Larger model: the Sonus Faber Lumina V (ranked higher, estimated 3.6/5).
Pros: Slim 3-way floorstanding tower with dedicated 4.7-inch midrange and dual 4.7-inch bass drivers extending reach to 40Hz. Sensitivity improves to 89dB, making it considerably easier to drive than the standmount Lumina models.
Cons: Small 4.7-inch bass drivers limit maximum deep-bass slam and high-SPL output compared to larger-woofer floorstanders. 4-ohm nominal impedance requires an amplifier comfortable with lower loads.

Sonus Faber Lumina I: $900.00 per pair Estimated Crutchfield eBay
Larger models: the Sonus Faber Lumina II (rated 3.4/5), the Sonus Faber Lumina III (estimated 3.5/5) and the Sonus Faber Lumina V (estimated 3.6/5).
Pros: Handcrafted Italian cabinet with multilayer real-wood front baffle and leather-wrapped enclosure. Front stealth reflex port built into the plinth allows placement close to back walls or on bookshelves without port obstruction.
Cons: Low sensitivity of 84dB demands substantial amplifier power to reach moderate volumes. Limited low-end extension (65Hz) and modest dynamic headroom restrict use to smaller rooms.
