Short answer: the Monolith Encore T6. It ranks #38 of 54 floorstanding speakers by sound quality at $800; the Monolith THX-365T ranks #39 and costs $900, so there is not much of a tradeoff to weigh.
What the Monolith Encore T6 offers: Three 6.5-inch pulp-cone drivers provide more displacement and cleaner cinema output than the B6, with good compression behavior at normal levels. Watch for: Despite its size, Erin measured F3 around 68Hz, so the tower does not eliminate the need for a subwoofer.
What the Monolith THX-365T offers: 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. Watch for: Erin measured F3 at 84Hz (F10 roughly 40Hz), so it categorically needs a subwoofer.
Buy the Monolith Encore T6. It ranks higher for sound quality than the Monolith THX-365T and costs less, so there is no real case for the other one.

Monolith Encore T6: $800/pair Amazon Monoprice
Pros: Three 6.5-inch pulp-cone drivers provide more displacement and cleaner cinema output than the B6, with good compression behavior at normal levels. Erin found the revised waveguided tweeter’s horizontal radiation consistent enough for predictable EQ, while the gloss-capped, heavily braced 49lb cabinet feels far above its price. The tower can produce useful midbass impact when crossed to a subwoofer.
Cons: Despite its size, Erin measured F3 around 68Hz, so the tower does not eliminate the need for a subwoofer. The native response needs equalization: crossover-region unevenness and excess top-octave energy prevent a fully neutral presentation. The four-ohm load and low-frequency phase angle warrant a robust amplifier, and the tall multi-driver array creates a narrower vertical listening window than a compact two-way.

Monolith THX-365T: $900/pair Amazon Monoprice
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.
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.
