OK thanks for the info on the room. @ozzy62 get some coffee and make sure the glass is half full....LOL. I have a couple of thoughts on how approach this and make use of your excellent Sim gear.
If you're into EDM you will really want to hear the mid-bass and even upper mid-bass (the deep bass is a foregone conclusion) and the stand mounts will not get you there. I would go for floor standers and add a sub in the future when the funds allow.
The room is tricky but your current layout needs to be changed. You stated the speaker are 9' apart and your listening position is 7' away which puts you "nearfield" That setup requires special speakers and are not what you're currently considering. Your speakers are just too far apart to allow them to do what their capable of. If this was my room, I would swap out the wide tv cabinet for something that would allow the speakers to be closer together. The speakers should be no more than an equilateral triangle from speaker to speaker to listening position. Good luck and cheers.
