IMHO the HWK is an excellent design for any use(HT or two channel). The subwoofers look to be great start. I have try all kinds of subs in the HWKs and all have had good results but the better duh sub the better duh sound. Adrian taught me that. What are yours plans, I mean what are you using the HWK for?

I am looking to get down to 16 Hz if I can. I was thinking of the HWK 18 with one 18, but I was rereading the suggestions Steve has for the HWK 15. I am now thinking of using 2 15" subs with both facing up to the large port Steve suggests that this will bring the bottom end down. Trying to keep with the parameters that Steve suggests, I have come up with the Adire Tepest 15, and 3 Dayton 15" subs that are close to the 10 cu ft vas and the "around 20 fs" as seen below.
I have been flip flopping around regarding making a decision and need to get going on this one.

I need 16Hz-about 90 Hz Pipe organ music mostly. Is that crossover point correct when the mains are 45-20,000 +/- 2dB?

As steve suggests regarding the 2 subwoofer position that I was looking at.
"This is a take-off of the first alignment that tends to shift the response down by 10 or 20 Hz and is considered a true isoberrek alignment. The large air spring between the woofers yields interesting results with different woofers.
and the less that .38 qts"

I think you are definitely on the right track. The HWK18 is a monster and I often dream of building one but the size pretty much puts out the fire to build. My HWK15 is also fair size and it will go low even with low/limited power. The woofer arrangement I have had the best luck with is two 15"s with the magnets in the seal section and the cones firing into the ported part of the enclosure. I would go ahead and build it. I am sure you will not be disappointed.
