“Guess I would need to listen… and decide which sounds best.” Now you got it. Panel speakers and box speakers have a very different presentation and different strong points. There is no substitute for listening. And don’t worry about stand mounts or floor standers. Just find something that sounds good to you. A stand mount on a stand doesn’t take up any more useable room space than smaller towers. I’m not saying towers are better, just that you shouldn’t limit yourself.
