Compression Horns for Far field listening

I have a interest in makinga  2 way, with a  FR 8 inch and sittinga  TI Horn compression midtweeter on top, SEller mentioned something about the TI horn is better for far field listening.
My room is 10x12, 
Is the compression Horn a good choice in that size room or should i stay with dome style tweeter.
The seller does not speak good english, what i think he is trying to get across is that his TI horn may not be ideal match for a  small room acoustics.
Anyone have experience with TI Horns can chime in please.
The TI Horn will sit on top of a  8 inch Full Range. 
Is this considered a  2 way??

Yes.
The directivity of a horn can be quite useful in a smaller room. When you get reflections from the side walls, when they reach the ear they are interpreted as harshness due to the short delay time. The directivity of a horn can reduce the sidewall reflections resulting in smoother sound.


For best results use a proper crossover so the full range driver isn't making the high frequencies.

Your seller is right.
He is correct abouta  TI Horn at near field,, <,IF>> one  has gain at say 100-120 db level, I listen at low db level, sitting 8 ft from speaker , near field blare is not going to be a  issue.
when i move to arizona, hopefully i will have a  bigger listening room, = can use a  bit more gain. 
I HATE  high db level, even if the speaker is the very best in the world.
so nera field  blare = no issue

Yes this is  what we need to figure out, 
Which value cap will we employ on the 8 inch FR?? 


The Horn  requires  either a  1uf or 1.2uf. 
Mundorf only makes a  1uf and 1.6 in the cap i want. SESGO cap.,,ohh look i now see they offer a  1.5 SESGO
So employinga   1uf vs 1.5, which allows more lower fq's to pass?
I never can remember how uf values work out.

You’ll need an inductor at least (for a 6db/oct slope), to block the highs from the 8" driver.     http://www.apicsllc.com/apics/Misc/filter1.html            Choose parts and a slope, via this, for the horn (1uF @ 8 Ohms = 17,000 Hz @6db/oct):  https://www.v-cap.com/speaker-crossover-calculator.php   You'll probably want a higher order than 2nd (6db/oct), for the horn.                        Give Madisound the driver specs and they can design a crossover, to fit your needs.     https://www.madisoundspeakerstore.com/crossovers-and-parts/                                             You’ll be needing a way to attenuate the horn, to match the 8's lower SPL.
