None of these diffraction elimination techniques can be accomplished on a narrow baffle because the round-over or absorption or whatever has to be a sufficiently large fraction of a wavelength in order to be effective. Therefore if we are serious about eliminating diffraction, the cabinet width is going to be fairly substantial.
And....digital room and digital speaker correction does not fix this.
Does not fix this.
Does not fix this.
It merely makes a smeary fuzzy mess that seems right or better.
For a while.
Then you finally hear it..... and toss the thing down the road to the next person who thinks it will be their savior.
IMO and IME, digital crossovers, room correction and speaker correction, are only charming to those who somehow can’t hear these pervasive and all encompassing distortions that are added into the mix.
There is a reason that the biggest names in loudspeaker design don’t do digital. I’m not comfortable saying these things but they are indeed true. Citing examples won’t work, as those are exceptions, not the rule, and I’m not sure about the aural capacities and directions of their proponents. First time I heard a digital speaker, I walked way unimpressed. The last time I head a digital speaker, I walked away unimpressed. Ground level faults that brick wall the designs. Ground level faults being inescapable - as they are as - the inclusion of digital.
All things being equal, which they never are..all things being equal...the analog crossover (active or passive) will exceed the sonic quality aspects of a digital crossover.
