Assuming 343m/s speed of sound, and xo @ 400 hz => wavelength = 343/400 = 0.8575m.
It has to be within 1/4 the wavelength to connect acoustically, right? So that would be 21.5 cm from the acoustic centers of the drivers. That's fairly close.
Does it need to be 21.5cm from both drivers, or the average distance between them in relation to 2123? Can make a drawing if that question is unclear.
Is it correct to use the XO point as a basis for calculating maximum distance between drivers? As the drivers overlap after the xo the distance will obviously change with frequency and can and will create lobing, right?
Can delay in the digital domain do anything to this particular problem within some constraint? Two drivers 10m apart can't sound like one driver no matter how much delay (if you're in the middle) obviously, but if we're talking about 10-20cm off from the maximum distance, will it work well?
