"Aren't those floorstanders a little too large for the room?"
In college, bigger speakers are ALWAYS better!
I found a pic I took of my old college dorm room system back in 1978. THose were the days. I worked part time at the local Tech Hifi which focused on refurbed gear that college kids could afford (maybe) and sold systems to all my dorm room buddies. I need to post it to my system page sometime soon.
Note: Space in the dorm room was limited so I had to go with smaller bookshelf speakers (OHM Ls which I still own) than I might have otherwise.
