a few random remarks on the top of my head:They've been out a long time, and I've heard the difference. So why aren't most consumer-oriented loudspeakers built as show in my diagram? (Apologies in advance for crude graphics!)
I've heard the difference
I think that is a different issue. Time alignment of speaker drivers is important to minimise phase shifts, mainly from the crossover, and for accurate reproduction of timbres around frequency change over points between the drivers.Time-aligned speakers sound silly to me. What if I move my head 6 inches up, down, to the left, or to the right? What if I tilt my head back or forward? How am I supposed to hold my head in the first place? Doesn't relative position of the head change each driver's position relative to my ears, so that the sound takes more or less time to get to them from each driver? Are the speakers designed for a head held perfectly vertically with ears the shape of perfectly flat boards on the sides at some angle? Shouldn't the drivers be attached to my ears by strings of precise lengths with adequate tension so that the drivers move to keep the same time alignment relative to my ears, all on a platform of precisely arranged and perfectly silent perpetual gyroscopes?
Right...physical alignment is wasted without a phase correct crossover.Incremental as it is.I think that is a different issue. Time alignment of speaker drivers is important to minimise phase shifts, mainly from the crossover, and for accurate reproduction of timbres around frequency change over points between the drivers.
Check it out: my speakers from 1977 are time and phase aligned. Crossover included!
