Hi Deon
Gauss K18 is pretty large (IIRC ~10cf) but may play well - 8 cubic foot box seemed about nuff IME for an 18" coupler - one below did pretty well outdoors - it was mellow in mis and highs compared to direct radiator but bass concussive distortion even with 50Hz compenent being down from flat was ~2% at 30vrms/50hz
lets see if earthlink who royaly screwed up my webspace access a year ago and whose out-sourced in India help isn't any help whatsoever still has the Gauss 5181 K18 plans)
K15 size 18" coupler vs k15 in-room
rough sketch of that that coupler with 3-panel reflector
idea to simplify to 2 panels above baffle
8cf coupler loaded with lower mass sigma type and topped with funky Frazier horn

taller 18" K ~8.2cf - upper aperture air velocity very high but plays decent bass
