Thank you! The JBLs were an absolute steal at $500 for the pair, and that also included my Soundcraftsmen preamp, a Soundcraftsmen tuner, a 200 watt power amp, and a 5 disc CD player on the side haha. Catch was the two hour drive to get it, but it was well worth it.
My last room was plagued by the sound of bare drywall reflections, therefore putting foam on the otherwise completely bare back wall is an attempt to remedy that. Behind the chair (not pictured) is a closet, so I can't really put foam there, plus the side walls are occupied. Soooo maybe it was a bit aesthetic too haha, but it seems to work well. Along with my bass traps it provides a simple, affordable, not too intrusive acoustic treatment solution. Of course there's always room for improvement, but didn't want to go too crazy as we are renting.
