I took a quick mental inventory of the many reference speakers I’ve owned and enjoyed, and they’ve all employed various methods of achieving sonic coherence. Some used precise driver alignment, and others used a single driver for all frequencies, but the result was always the same. (If you’re interested, the Dahlquist DQ-10 and Ohm F speakers are two of them.) To my ears, sonic coherence is the most important aspect of music listening and home theater sound, and its subjective benefits are very real. Speakers that accomplish this can lift the veil that shrouds many speakers and rise above the sense of sound reproduction. They sound more like you would imagine the original performance.
