True, 6 are enough, 8 are better. If I was modding a T IVa I would have tried to fit 8 into the slot. If I get around to building new frames I will extend the line to 8 per channel. With 8 per channel I can lower the XO from 250hz to 200 hz. It might seem foolish to put in that much for such a small change but it is a rather critical point in the freq spectrum for fundamentals so you want this much faster driver to do the work rather than the bass panels.
Using Neo8-S I would have been able to cross over that low with 6 drivers per side. Extending to 8 drivers per side is not necessarily going to have the same useful extension at the bottom. At <200hz you have much higher energy content to music and this introduces large vibrations to the mid/tweeter panel and thus IMD to the ribbons. So this would require better isolation for the tweeter and a stiffer frame.
