Do you have the T/S parameters for the drivers, and can you post them?
And yeah a 28 Hz tune is pretty high for HT, especially with a 15".

HT box size and port for a JBL MKII 15" ?

here is the ported box suggestion but it's for Car audio so the tune is to high in frequency and box maybe to small for efficiency?

How big is the room the sub is in? Large and open or a closed off room?
You'd only need one channel of the K2, but you could do 8cuft tuned to 15 Hz with two 4"x34" (or one 6"x38") round ports, or a 15"x1.75"x35" slot port. So you could build two and use the one amp. It would need a 12 Hz subsonic filter if the amp doesn't have one built in already.

I JUST posted this info in another thread.
333 liter Tapered-Tapped Quarter Wave Tube (T-TQWT or negative flare tapped horn [TH]).
I supplied a 333L BR and a 333L TH for comparison.
Bare in mind, all 3 enclosures can be built with 7 panels in their simplest form (not including bracing).
In their simplest form, the 2 TH's would be 71.5"H x 17.5"W x 20.25"D.
HT = negative flare.
Music = positive flare.
