Short answer: the ELAC DB63 is the more forgiving value bookshelf, while the Klipsch RP-600M II rewards careful placement with a more energetic presentation. ELAC is ranked 49 of 222 and Klipsch is 123 of 222.
The DB63 combines a 6.5-inch aramid woofer with broad radiation and a cabinet that works well nearer a wall, though its lower-mid dip can make voices sound lean. The RP-600M II improves its waveguide over the earlier model, but its on-axis treble still runs hot. Toe it out by about 20 degrees, or use the grille, if you want to reduce that brightness.
Buy the ELAC Debut 3.0 DB63 if you want a smoother, easier-to-place bookshelf speaker for everyday listening.
Buy the Klipsch RP-600M II if you like a lively forward sound and will take time to optimize its placement.
