Should we pay more attention to delays in sound?

That’s why I love Tannoy speakers. It’s all right there. 

Tannoy single driver designs produce a singular source of directionality, this is their design philosophy, and many like yourself like/prefer the results.

however, they are not time aligned.

high frequencies travel faster than low frequencies. time aligned speakers have the front faces slanted, or separate enclosure(s) for the upper mids and perhaps a separate enclosure for the tweeters, some super-tweeters. Those separate enclosures are staggered rearward from the face of the woofer and lower mids.

All this to have the highs ’start’ further back, so that at typical listening distances, they arrive ’time aligned’.

My JSE Infinite Slope Model 2’s were the most accurate speakers I owned. Aside from the steep crossover, excellent driver choices, ... the front panel was slanted for time alignment.

My current speakers are flat faced, I put a 1-1/2" block under the front edge, tilting the entire enclosure ’back’ for 3 reasons.

1. time alignment

2. tweeters dispersion becomes directly at seated ear height

3. angle of dispersion of all drivers, especially bass to floor, and everything off the rear wall is significantly altered, the complex mixture of reflections is mixed/weakened relative to the initial sound waves.

tilting a single driver can get the 2nd and 3rd benefits, but time alignment will not/cannot be achieved. It will not alter the fixed time alignment.

@elliottbnewcombjr,
Here is a short article about time aligned loudspeakers.

Hey guys, .... I don't want to bust your bubble, .... but most speakers, even high end brands, ... are not time aligned.  Based on articles I have read, Vandies and Green Mountain Audio are supposed to be time aligned.  I believe both brands use a recessed tweeter and 1st order crossovers.  Roy Johnson of Green Mountain Audio wrote some great articles that explain why higher order crossovers screw up time coherence.  You'd have to find the articles to understand the science.

The problem of using 1st order crossovers is that the various drivers may be operating outside their optimal frequency range.  So special drivers must be used to achieve good results.  

In any case, most of us are happy with our speakers, even if not time coherent. 

If you want to see bench tests of your favorite speakers, check out John Atkinson (Stereophile) bench test results.  For example, JA measured the Vandy Model 7 MK II here: www DOT stereophile.com/content/vandersteen-model-seven-mkii-loudspeaker-m7-hpa-monoblock-power-amplifier-vandersteen-seven
