Short answer: the Revel Concerta2 F35. It ranks #30 of 188 floorstanding speakers by sound quality (rated 4.5/5) at $900 and is still sold new; the Triangle Esprit Antal Ez ranks #182 (rated 2.5/5) and is discontinued, so it is only an option used.
The Revel Concerta2 F35 is the more accurate, deeper-bass pick. 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 2.76 for the Triangle Esprit Antal Ez. Its bass reaches about 70Hz before falling 3dB, against 85Hz for the Triangle Esprit Antal Ez. Watch for: F3 of 61Hz and F10 of 39Hz mean a subwoofer is needed for real bass extension.
What the Triangle Esprit Antal Ez does well: Predicted in-room response sums rather nicely aside from the resonance and bass issues. Watch for: Resonance around 260Hz and a number of other resonances show up on-axis, along with a dip in bass response.

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.

Triangle Esprit Antal Ez: $1,799 per pair Discontinued eBay
Same family: the Triangle Esprit Titus EZ (bookshelf, rated 3.6/5).
Pros: Predicted in-room response sums rather nicely aside from the resonance and bass issues. Horizontal beamwidth of about ±50 degrees is reasonably controlled. Measured bass extension of 85Hz (-3dB), with a measured sensitivity of 90.7dB.
Cons: Resonance around 260Hz and a number of other resonances show up on-axis, along with a dip in bass response. Two distinct distortion sources (one around 250-300Hz, another around 3-4kHz) already cross the reviewer’s audibility threshold even at moderate output, and get much worse at 96dB SPL/1m, where distortion broadly exceeds 50% relative level across large parts of the spectrum. Directivity is not great overall. The reviewer does not recommend it. Discontinued.
