Short answer: the Arendal Sound 1723 Monitor THX if sound quality matters most, the Klipsch RP-600M II if price matters most. The Arendal Sound 1723 Monitor THX ranks #55 of 222 bookshelf speakers, rated 4.2/5, at $2,400. The Klipsch RP-600M II ranks #123, rated 3.7/5, at $449.99, $1,950.01 cheaper.
Why pick the Klipsch RP-600M II: Bookshelf speakers with a large horn tweeter, wide soundstage, high efficiency and bi-amp ready terminals. Watch for: On-axis, the treble runs notably hot (even hotter than the original Klipsch RP-600M in some respects) and needs about 20° of toe-out or the grille installed to sound balanced.
The Arendal Sound 1723 Monitor THX is the better-sounding, deeper-bass option. A THX certified monitor with dual 8 inch woofers, a waveguide tweeter, and sturdy build for high output home theater rooms. Its bass reaches about 63Hz before falling 3dB, against 70Hz for the Klipsch RP-600M II. The catch: 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 Klipsch RP-600M II when the price outweighs sound quality for you, and the Arendal Sound 1723 Monitor THX when sound quality outweighs the price instead.
