horn or line array?

I have plenty of good drivers to build some test sealed or ported box speakers, subs, etc and doing a lot of room treatment and DIY cables. I wired two separate dedicated and fully shielded AC lines and moved the breakers around to put all the noisy stuff on the opposite leg.

Just pointing out I am dedicated to make this the best RV system I possibly can, not spend a fortune on it, not needed when done right and I know the limitations I face but also I have had incredible success in vehicles much smaller than this so hope to make the HORNS work:)

Horns!

Always my all time favorite even in car audio which I have done quite successfully a couple of times. Currently remodeling our full time RV, added 1.5 ft to the length for more room for the system. I will test my beloved and highly modified Edgarhorn Slimline, Building some XDS open baffle to test as well and have some small KEF line arrays we used for years in RV's.  A tough challenge to make anything work well in the RV but going to make a go of it and hope the EH work as Doc Edgar was a freind of mine.
