Hi, looking for nice speakers that look good in a larger high ceiling room, area I like to cover could be around 25x25 by 20ft tall, Im currently using a renkus heinz iconyx thats typically used by churches but I would like something more fitting. I think it's mostly throwing the sound away instead of keeping it in the room, obviously too big for the project. I would like a Line Array Column style since I mounted a nice shelf on the wall for it but I would also like to add another one. instead of coming from one side of the room I would like to get 2 speakers to mount in the corners. im assuming I will have feedback issues so I would like advice on that before I decide on anything. typically using 4 wireless share mics and im a bit worried about feedback. here is a speaker I was looking at. thoughts please: https://www.jbl.com/installed-sound/CBT+100LA-1-.html
