Short answer: the ELAC Debut 3.0 DF63, unless you want the Klipsch Forte IV’s heritage bass. The Forte IV is a three-way heritage design with a 1-inch titanium tweeter, a 1.75-inch compression driver for the midrange, a 12-inch woofer and a 15-inch passive radiator, but it is somewhat recessed in the 1.5-4kHz presence region, so some tracks sound dull. The DF63’s own 200-300Hz resonance adds a droning coloration to female vocals.
Buy the ELAC Debut 3.0 DF63. It is rated higher for sound quality than the Klipsch Forte IV and costs less, which makes it the one to get unless you need something the other one does better.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
