Short answer: the ELAC Debut 3.0 DB63. Both are rated 4.2/5 for sound quality (#50 and #56 of 214 bookshelf speakers), and the ELAC Debut 3.0 DB63 costs $499 against $2,400 for the Arendal Sound 1723 Monitor THX, with sound quality a draw, the lower price decides it.
The case for the ELAC Debut 3.0 DB63: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Watch for: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow.
The Arendal Sound 1723 Monitor THX is the deeper-bass choice. Independent ASR Klippel data shows a narrow 1.8dB reference band, 0.391 listening-window smoothness, and useful bass extension to 48.3Hz at -6dB. Its bass reaches about 63Hz before falling 3dB, against 76Hz for the ELAC Debut 3.0 DB63. Watch for: The measured on-axis average absolute deviation is 0.979dB and the sound-power directivity-index standard deviation is 3.63, so its response and dispersion are less even than the best alternatives.
Buy the ELAC Debut 3.0 DB63. Both are rated the same for sound quality, and it costs $1,901 less than the Arendal Sound 1723 Monitor THX.

Older model: the ELAC Debut 2.0 B6.2 (ranked lower, rated 3.5/5). See every ELAC Debut generation.
Same family: the ELAC Debut 3.0 DB53 (smaller bookshelf, estimated 3.9/5), the ELAC Debut 3.0 DF53 (smaller floorstanding, estimated 4.2/5), the ELAC Debut 3.0 DF63 (larger floorstanding, rated 4.2/5), the ELAC Debut 3.0 DC53 (smaller center, estimated 3.4/5) and the ELAC Debut 3.0 DC63 (larger center, estimated 3.5/5).
Pros: 1” aluminum dome tweeter with a distinctive partial-lens waveguide design paired with a 6.5” third-generation aramid fiber cone woofer, in a robustly built cabinet for the price. Shallow bass rolloff (F3 76Hz, F10 40Hz) allows placement close to a wall without excessive boominess, useful for smaller living rooms. Solid measured performance for the price: on-axis linearity within about 2.5dB, impedance dipping only to about 4.4 ohms (easily AVR-driven), and roughly 20-26dB of usable dynamic range. A clear improvement over its sibling ELAC DB62, which has a sibilance issue tied to the crossover that can’t be fixed with EQ. Wide horizontal radiation of about ±60°, giving a spacious soundstage. Distortion looks good at a moderate 86dB and still reasonable at 96dB. Takes well to EQ correction: the reviewer provides a specific filter set (a low-shelf boost at 650Hz plus peaking cuts/boosts at 550Hz, 660Hz, and 3kHz) that meaningfully smooths out its known deviations. Measured bass extension of 76Hz (-3dB), with a measured sensitivity of 86.2dB.
Cons: A dip in the lower midrange (300-600Hz, about 1.5dB) reduces vocal warmth and can make voices sound slightly hollow. A high-Q resonance around 650-750Hz shows up clearly in measurements, though the reviewer couldn’t reliably hear it in his own A/B testing. A dip around 2-3kHz (roughly 1-2dB) slightly reduces speech intelligibility and attack in the upper midrange. Directivity droops above about 2kHz as the midwoofer narrows toward its beaming frequency while the tweeter’s pattern behaves differently: an inherent trade-off of physically separated drivers that can’t be fully corrected without introducing other issues. Multitone distortion crosses the reviewer’s 3% threshold in the 200Hz-1kHz range, and adding a subwoofer at an 80Hz crossover only modestly reduces it. Toeing the speaker away from the listener loses noticeable top-end air and cymbal energy, giving a softer upper register. Practical loudness ceiling is around 90dB at typical listening distance before midrange distortion and bass attack begin to degrade. Still needs a subwoofer for extension below about 40Hz.

Arendal Sound 1723 Monitor THX: $2,400 per pair Arendal Sound eBay
Same family: the Arendal 1723 Bookshelf S THX (smaller bookshelf, ranked higher, rated 4.2/5), the Arendal Sound 1723 Monitor S THX (smaller bookshelf, ranked lower, rated 4.1/5), the Arendal Sound 1723 Tower S THX (smaller floorstanding, estimated 4.2/5), the Arendal Sound 1723 Tower THX (larger floorstanding, estimated 4.3/5), the Arendal Sound 1723 Center S THX (smaller center, estimated 3.7/5) and the Arendal Sound 1723 Center THX (larger center, estimated 3.8/5).
Pros: Independent ASR Klippel data shows a narrow 1.8dB reference band, 0.391 listening-window smoothness, and useful bass extension to 48.3Hz at -6dB. Its preference score rises from 5.16 to 7.30 with a subwoofer. Dual 8-inch woofers, a waveguided tweeter, robust HDF construction, and THX Ultra certification suit high-output rooms. Measured bass extension of 63Hz (-3dB).
Cons: The measured on-axis average absolute deviation is 0.979dB and the sound-power directivity-index standard deviation is 3.63, so its response and dispersion are less even than the best alternatives. Bass reaches only 63Hz at -3dB despite the very large cabinet, and the 1.239 low-frequency Q indicates a pronounced alignment. At roughly 60 lb each, these require substantial stands and space.
