I have a DIY/experimenters WMTMW format arrays, and I listen quasi-near field. BUT my woof to woof spacing is a mere 16" and midrange spacing is 6" center to center. (I use truncated 4" mids and a small-flange neo-tweeter that's about 1.6" high, and mid-bass drivers are 7". These driver sizes are all quite small as far as WMTMW designs go, with only the odd mid-dome variations having tighter spacing.
Large-distance arrays are often said to work better for far-field because drivers don't *blend* as *quickly* (not less well, just further away).
But the biggest question of all is: why go through the trouble of time-aligning when you're not going for a transient accurate result anyways? You can only dial in the "correct" distance (delay) for a given frequency.
Big difference between delay and group delay.
Cheers,
Presto
