maybe...but certainly not the perfect quality control at Chario (woofers: one in 4 ohms and the other in 8 ohms !)

Totally! ... So, that means we only need one really big sub woofer? ...

How about this one: " Larry Ellison of Oracle According to Wired magazine, he uses an entire drained swimming pool as a subwoofer for his rock-concert-sized home theater system. ... "

Yes, really big.

Hrmmm, back on topic….

Re: interaural time difference, “With a sound input with a frequency closer to 1500Hz the wavelength of the sound wave is similar to the natural time delay. Therefore due to the size of the head and the distance between the ears there is a reduced phase difference so localisation errors start to be made”

So no point in trying to minimise phase diffs in xovers below ~1500Hz?
