I own F200A drivers (the big brother of the F120A) and have them in Bob Brines floorstanding mass loaded transmission line cabinets. Their Qts is around 0.4, which matches them best to bass reflex or transmission lines. Except for very low organ, my speakers don't need a sub for music. Louis, from Omega Speakers has built a couple of pairs of standmounts using the F120A and the owners are very well pleased. I've been a user/fan of transmission lines for 25 years and much prefer them to horns as playing deeper, being more musical, and much smaller for a given bass response.

Most Fostex drivers have low Qts (around 0.2) that lends them to horn loading. Don't underestimate the importance of proper matching of driver to enclosure.

I believe that the F120A could be one of the very best extended range drivers available in that size. There is no perfect driver/speaker, each must chose their own compromises (efficiency, bass response, beaming, build quality, price, colorations, etc.).
