A couple of times you mentioned the silliness of time alignment in speakers. Being a novice in such matters could you please explain to me, why time alignment is snake oil? I mean it seems to make sense to me.

Thanks for your time.

Then the difference in path length results in one signal arriving 0.5/1150 or 0.4 milliseconds later? Not likely to be noticable even by a bat.

And then you get to the really silly part - on what axis are the voice coils equidistant from your ears? Maybe you have to put some paint cans under the couch legs to make sure you're on axis.

What is possible, is near alignment. This is what is important. If you can keep sound sources within 1/4λ of each other, then they'll sum properly and won't exhibit frequency anomalies. This is possible, and it's desirable.

To tell the truth, most good loudspeakers sum true at least on-axis. If they don't, it shows up as a spiked dip in the response curve. But no loudspeakers are actually time aligned through the audio band. Use of the phrase "time aligned" is just sales rhetoric.

Thanks
