Very COOL. I always wanted to get a pair of Maggies. I think you can download placement instructions. They are critical of placement, but will reward you with tremendously. Feed them a fair amount of power, they are hungry. You might want to pair them with a sub. I would search for a used M&K on eBay.
The big daddy speakers we were doing had two 30 inch ribbons per speaker, so they were the Mids and highs. Four 8’s & a 13 with a 12 foot folded port tube per side. Bi-amped with 500 watt/channel McIntosh amp on the mid-bass & bass, 250 on mids/highs.
Those KLHs are cool too, nice project! That is a crazy looking bass driver
