Short answer: the Power Sound Audio MT-110-M. It ranks #49 of 131 bookshelf speakers by sound quality at $1350; the Arendal Sound 1723 Monitor THX ranks #50 and costs $2400, so there is little reason to consider the other one.
What the Arendal Sound 1723 Monitor THX offers: 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 4.26 to 6.39 with a subwoofer. Dual 8-inch woofers, a waveguided tweeter, robust HDF construction, and THX Ultra certification suit high-output rooms. 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. 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.
What the Power Sound Audio MT-110-M offers: Made in the USA with a 1” polyimide compression tweeter on a cast aluminum exponential horn plus a 10” high-efficiency neodymium woofer, both BMS-made drivers. Reasonably high measured sensitivity (about 92.5dB at 2.83V/1m), so it doesn’t need much power to play loud. Excellent dynamic range - frequency response barely shifts (about 0.5dB deviation) from 76dB to 102dB output, which the reviewer calls completely acceptable headroom. Not fatiguing or bright despite the horn-loaded compression driver - the constant-directivity horn avoids the artificially flat, reflection-heavy in-room high-frequency buildup that some waveguide designs suffer from. Sealed cabinet design means placement near a wall is less of a bass-reinforcement concern than with a ported design. Solid build quality using threaded nutserts rather than screws driven directly into the cabinet wood. Watch for: A mid-range bump makes the tonal balance sound too thick and needs 2-3 bands of EQ to flatten out; correcting it also pulls measured sensitivity down to about 90-91dB in practice. F3 of 113Hz and F10 of 68Hz mean this doesn’t get low without a subwoofer - in the reviewer’s room it barely reached 70Hz with any real authority. Rising distortion in the upper mid-range, likely from woofer breakup, that lines up with anomalies seen in the impedance sweep above 500Hz - not a major concern but worth noting. The reviewer explicitly frames this as a home theater speaker rather than a stereo/music speaker.
Buy the Power Sound Audio MT-110-M. It ranks higher for sound quality than the Arendal Sound 1723 Monitor THX and costs less, so there is no real case for the other one.
