Short answer: the Arendal 1961 Monitor. It ranks #8 of 160 bookshelf speakers by sound quality (rated 4.3/5) at $1,150 and is still sold new; the ELAC BS U5 ranks #108 (rated 2.9/5) and is discontinued, so it is only an option used.
The ELAC BS U5 is the more accurate, deeper-bass choice. This slim three-way coaxial design (an Andrew Jones creation) shows a fairly even on-axis response up to 3kHz, with off-axis behavior notably smoother than the on-axis curve. Its measured preference score, a predictor of how neutral it sounds, is 4.71 against 3.38 for the Arendal 1961 Monitor. Its bass reaches about 63Hz before falling 3dB, against 84Hz for the Arendal 1961 Monitor. The catch: Distortion is very high right at both crossover points (around 270Hz (mid-range) and 2700Hz (tweeter)) at both 86dB and 96dB SPL/1m, exceeding 3% at the mid-range crossover.
The Arendal 1961 Monitor is the better-sounding option. A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion, and overall really good neutrality: one of the reviewer’s top 10 picks under $1,500 across roughly 250 speakers tested. The catch: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well.

ELAC BS U5: $856 per pair Discontinued eBay
Pros: This slim three-way coaxial design (an Andrew Jones creation) shows a fairly even on-axis response up to 3kHz, with off-axis behavior notably smoother than the on-axis curve. Predicted in-room response looks like it should give good tonality. Vertical directivity is better than average, a benefit of the coaxial layout. Measured bass extension of 63Hz (-3dB), with a measured sensitivity of 83dB.
Cons: Distortion is very high right at both crossover points (around 270Hz (mid-range) and 2700Hz (tweeter)) at both 86dB and 96dB SPL/1m, exceeding 3% at the mid-range crossover. Minimum impedance dips to 3.4 ohms with a possible resonance around 500Hz visible in the impedance/phase curve. Discontinued.

Arendal 1961 Monitor: $1150 per pair Arendal Sound eBay
Same family: the Arendal Sound 1961 Bookshelf (smaller bookshelf, ranked lower, rated 4.2/5), the Arendal 1961 Tower (floorstanding, rated 4.4/5) and the Arendal Sound 1961 Center (center, rated 3.6/5).
Pros: A physically robust build the reviewer calls “a little bit of a tank,” delivering low compression, low distortion, and overall really good neutrality: one of the reviewer’s top 10 picks under $1,500 across roughly 250 speakers tested. Works well both as home theater mains and as surrounds. Independent ASR Klippel measurements corroborate the low-distortion finding: THD at 86dB SPL/1m stays well below the reviewer’s audibility threshold, and even at 96dB SPL/1m it stays “far better than most bookshelves” thanks to the built-in high-pass filter that protects the woofers. Measured bass extension of 84Hz (-3dB), with a measured sensitivity of 85.9dB.
Cons: Bass rolls off around 70-80Hz, so it cannot be used as full-range mains for music without a subwoofer, and a sub is recommended for home theater use as well. Vertical radiation window is narrow, typical of MTM (mid-tweeter-mid) layouts (tighter than a standard two-way’s roughly ±20°) so a second home theater row sitting above or below the tweeter axis will hear a noticeably different tonal balance. ASR’s CEA2034 measurements show the response is elevated above 2kHz with resonant peaks around 3kHz and 9kHz, leading the reviewer to predict it will “likely sound bright.” Those same resonances show up as lingering ridges in the cumulative spectral decay (waterfall) at 96dB SPL/1m.
