Yes and the not obvious part is that particular combination can comfortably go frightfully loud. Since most everything loudspeakers do wrong or adds to the signal, increases faster with input level than the desired sound does.
The phrase "headroom is your friend" comes in to play very powerfully here. The loudest it would ever play in a living room is idling or lower.

How that horn would work with one of the Faital 1.4s?Here's what I get with the 140\142 combo. good for 600hz for low power use. Still close to 1/2 wavelength woofer interaction. The only aspect I don't like is the 60 degree horn and that's only my room interaction. Other rooms 60 degrees may be perfect.
RCF has some nice smaller, cheaper horns but won't make it to 300hz.

"How that horn would work with one of the Faital 1.4s?"
It's polar pattern would be the same, the frequency response would likely be a little different. This horn is longer and will load the driver to a lower frequency than the 142 and it's larger size means it holds the pattern to a lower frequency.
Horns can give you a large "near field" where the direct sound is substantially louder than the late room sound. not only is there much less sound going to the rear but less to the sides too.
Position, imagine those horns one on each side with a little light where the driver (exit slot in this case) is.
Now imagine mirrors on your walls. You can move the speakers closer to your side walls than normal.. as long as the horn is toed in and you can't see the light bulb in the mirror on the side wall at the listening position. Your avoiding a side wall reflection where the horn has pattern control.
No driver has a flat power response so some EQ is normal and proper EQ corrects mag and phase at the same time.
