Short answer: the MoFi SourcePoint V10 Master Edition. It ranks #4 of 228 floorstanding speakers by sound quality, rated 4.8/5, at $7,995. The Klipsch Heresy IV ranks #222, rated 2.3/5, at $3,599.98, $4,395.02 cheaper, a saving that is not big enough to make up the sound-quality gap.
The MoFi SourcePoint V10 Master Edition is the more accurate, deeper-bass choice. Big floorstanding speakers with a 10 inch coaxial driver, precise imaging and bass deep enough to skip a subwoofer. Its measured preference score, a predictor of how neutral it sounds, is 5.00 against 2.27 for the Klipsch Heresy IV. Its bass reaches about 38Hz before falling 3dB, against 77Hz for the Klipsch Heresy IV. The catch: Moderate sensitivity (~89 dB) means amplifier power requirements higher than many alternatives.
The case for the Klipsch Heresy IV: A compact horn loaded speaker with a 12 inch woofer and very high sensitivity, giving lively dynamics from modest amplifiers. The catch: Erin measured a 77Hz F3 and response rolling away near 100Hz in-room, so a subwoofer is required for modern full-range reproduction.
Buy the MoFi SourcePoint V10 Master Edition. It is rated higher for sound quality, and saving $4,395.02 with the Klipsch Heresy IV does not make up for the sound-quality gap.
