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.
