Short answer: the Revel Concerta2 F35. It ranks #31 of 226 floorstanding speakers by sound quality (rated 4.5/5) at $900 and is still sold new; the Monolith Encore T6 ranks #127 (rated 4.0/5) and is discontinued, so it is only an option used.
The Revel Concerta2 F35 is the more accurate option. Two-and-a-half-way, four-driver design: a 1” aluminum dome tweeter on a waveguide, a 5.25” mid-range, and dual 5.25” mid-bass drivers in a rear-ported cabinet. Its measured preference score, a predictor of how neutral it sounds, is 5.35 against 4.57 for the Monolith Encore T6. Watch for: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension.
What the Monolith Encore T6 does well: Three 6.5-inch pulp-cone drivers provide more displacement and cleaner cinema output than the B6, with good compression behavior at normal levels. The catch: Despite its size, Erin measured F3 around 68Hz, so the tower does not eliminate the need for a subwoofer.

The Two Speakers In Full
Revel Concerta2 F35: $900 per pair Crutchfield eBay
Same family: the Revel Concerta2 M16 (bookshelf, rated 4.1/5), the Revel Concerta2 F36 (larger floorstanding, ranked higher, estimated 4.6/5) and the Revel Concerta2 C25 (center, rated 4.1/5).
Pros: Two-and-a-half-way, four-driver design: a 1” aluminum dome tweeter on a waveguide, a 5.25” mid-range, and dual 5.25” mid-bass drivers in a rear-ported cabinet. Measured sensitivity of 89.4dB closely matches the 90dB spec, and distortion looks good at both 86dB and 96dB, holding up well even with a high-pass filter applied. At its sale price of $900/pair, down from full retail, the reviewer calls it a “no-brainer,” undercutting comparable budget floorstanders like the ELAC Debut 3.0 DF63. Frequency response and directivity mismatches are largely EQ-able, since most of what shows up in measurements traces to physical tweeter/mid-range separation rather than a fundamental flaw. Compression is fairly well controlled for the price: about 1dB of loss around 100Hz under long-term compression, described as “par for the course” at this cost. Measured bass extension of 70Hz (-3dB), with a measured sensitivity of 89.4dB.
Cons: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension. A dip in the lower midrange/2-3kHz region reduces attack and detail, and a peak around 5kHz adds some edge and sibilance in the lower treble. A peak in off-axis energy around 3kHz reflects off sidewalls at roughly 60-70° off-axis and arrives louder than the direct sound: this specific issue can’t be fixed with EQ (boosting the direct sound would boost the stronger reflection too) and would need acoustic absorption to properly address, though the reviewer considers it a minor, optional fix at this price. A couple of minor resonances appear in the impedance plot, including one around 300Hz that may partly explain a subtle sense of vocal warmth noticed in listening, though it’s more likely room-related. Minimum impedance around 3.8 ohms. Short-term compression testing shows some increased distortion in the tweeter and higher-frequency compression at loud output.

Monolith Encore T6 Discontinued eBay
Same family: the Monolith Encore B6 (bookshelf, rated 3.9/5) and the Monolith Encore C6 (center, rated 3.7/5).
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. Measured bass extension of ~68Hz (-3dB).
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. Discontinued.
