Question Diy small active PA speakers with off shelf components

lets say we take beyma sm115/n/8 midbas,tweeter rcf nd 1411m on eighteensound xt 1086 horn, and put it inside custom reflex cabinet tuned to 35hz and made by local woodworker.

now for amplifier cant decide, some sort of quick all in one solution would be good.

why not buy lets say JBL EON 615 replacement amplifier module and mount it , not sure what xover freq. but it has some sort of dsp so it should be adjustable?

this is for small size PA system and intent is to not need bass bins and to have reasonable output for to max 100 people on open places and what is point of my asking to be cheap, easy and fast to assemble, reasonable db and high quality output.

how feesible this solution of parts looks? any suggestions welcome thank you

RCF ND 1411-M
Eighteensound XT1086
Beyma SM-1155N

That is a lot of money for a DIYed PA rig that you won't be able to move if you get tired of it. I'd closely evaluate commercial offerings by giving these a good and loud listen in a large space. Maybe a less expensive and less powerful product would serve your purpose as well too.

I woundn't count on that crossover frequency can be changed easily. You propably have to do some hacking.

I think that you've made a sensible decision and the JBL 615 looks very appealing.

The great thing about the EON is that it works very well outside. Good choice!

I cant say i am too satisfied with eons,for my ear a bit weak in bass region or maybe it is bad workshop acoustics. will test them outside in few days to be sure.
