if someone is whac K y enough to attempt new couplers - how might they make a go for bulk, proportion and tuning? would they wish to consider a possible coupled-cavity peak?(K-designer Moray James appears to prefer a t-line rear load to Karlson's ported chamber)
115BK EVM15L baffle = 20 degree, theres a 4.5" perpendicular board then 50 degree deflector (side view in post below)
42 inch tall 18" woofer coupler with 8.6CF bulk (~12% larger than K15)
ground-plane dips seem characteristic of curved reflectors seen so far (only 3)
32 inch coupler with up to 1.2" gap, 23 degree baffle and 10 degree board
Z with 6" cap added only to front chamber
what happened when 20L was added as a fold-over stub to front chamber only
