Short answer: pick the Monolith THX-365T if you want sound quality that has been measured and ranked; the Emotiva Airmotiv XT2 is unmeasured so far, so its case rests on features and price.
What the Emotiva Airmotiv XT2 offers: A three-way tower with a 25mm x 32mm Airmotiv folded ribbon tweeter, a 5.25” woven fiber midrange in its own sub-enclosure, and three 6” long-throw woofers, crossed at 430Hz and 3.1kHz.
What the Monolith THX-365T brings: The coaxial midrange/tweeter produces coherent horizontal and vertical coverage through most of the vocal band, while twin 6.5-inch woofers deliver good 88.6dB measured sensitivity.
Price: the Emotiva Airmotiv XT2 lists at $999 and the Monolith THX-365T at $900.

Emotiva Airmotiv XT2: $999 per pair Discontinued Emotiva eBay
Older model: the Emotiva Airmotiv T2+ (rated 4.2/5).
Pros: A three-way tower with a 25mm x 32mm Airmotiv folded ribbon tweeter, a 5.25” woven fiber midrange in its own sub-enclosure, and three 6” long-throw woofers, crossed at 430Hz and 3.1kHz. Emotiva rates it at 40Hz to 27kHz (±3dB) and 90dB (2.83V/1m) efficiency. A 31mm braced baffle, rear port, bi-amp terminals, outrigger feet with spikes, magnetic grilles and a five year warranty.
Cons: No independent measurements have been published yet, so it can’t be compared with the Airmotiv T2+ it replaces, which Erin measured reaching about 32Hz (-10dB) from two 8” woofers. The XT2 swaps those for three 6” woofers. Its 4 ohm load calls for an amplifier of 100W or more that is comfortable with 4 ohms. It weighs 22kg per speaker, and it is sold mainly direct from Emotiva, where it currently shows sold out. Discontinued.

Monolith THX-365T: $900 per pair Amazon Monoprice eBay
Pros: The coaxial midrange/tweeter produces coherent horizontal and vertical coverage through most of the vocal band, while twin 6.5-inch woofers deliver good 88.6dB measured sensitivity. Erin found low distortion above the bass and useful dynamic capacity for home theater; the sealed enclosure also makes the intended 80Hz THX crossover predictable. An integrated up-firing Atmos module and THX Ultra certification make this a compact, unusually versatile LCR/tower. Measured bass extension of 84Hz (-3dB), with a measured sensitivity of 88.6dB.
Cons: Erin measured F3 at 84Hz (F10 roughly 40Hz), so it categorically needs a subwoofer. Native response has enough upper-mid/treble irregularity that Erin recommended it only with EQ. Although mostly above four ohms, impedance falls to nearly 3 ohms with an adverse phase angle, potentially stressing an AVR; a separate four-ohm-capable amplifier is prudent. The Atmos module adds cost and height but cannot substitute for properly placed ceiling speakers.
