Does Time alignment and Phase coherency make for a better loudspeaker?


Some designers strive for phase and time coherency.  Will it improve sound quality?

Ever heard any of John Fuselier’s loudspeakers from "back in the 80’s"? Time and phase aligned, with excellent coherency and pulse response. Soundstaging and imaging were exceptional. Spectral balance varied between different iterations/models, but all had an uncanny ability to sound real. If you are familiar with them, then you should know exactly what I am talking about.

Time alignment is about when the sound reaches your ears from the drivers in your speakers. Getting it right adds realism to the sound. Wilson Speakers are built to be listened to time aligned. The smaller models are not adjustable in that regard and require a setup within some relatively tight parameters to sound best. Not to far from the listening posistion or too high/low. The middle and upper models have adjustable modules for each driver alowing more flexbility for the seating posistion and room size. Is it night and day? Yes if you are used to listening to your system with $50K and up speakers, well set up and driven by really good amplification and sources, so at least six figure system. Otherwise, not so much. This is a final touch for well designed systems.

I phase and time align every concert venue I mix (hundreds overe decades) , and my home rig also. I never said phase and time don't matter, I simply was pointing out that live music with no sound reinforcement is never specifically adjusted for time and phase, and it still sounds great. Musicians hopefully play in sync and in tune, but not always perfectly and it can still like magic.
