My room dimensions are 10.5' x 18' x 6.5'. I primarily watch movies and don't turn the volume up that loud. I would say I listen at roughly 80dB from 6ft away. I just noticed that one of my floor standers has 3 small nicks on the top edge of the speaker. It is not that noticeable unless you view the speaker up close. I am not sure if I did this or best buy did. I did buy the speakers open box and I didn't notice any nicks when I brought the speaker home. Because of this I am not sure that I could return my speakers now because of the nick. Actually, I could return the other floorstander and the center speaker; just not the floorstander with the nick.
I probably wouldn't return my speakers at this point anyways. Since the front three were all open box I only box $180 for the pair of floorstanders and $70 for the center speaker. The pair of sp-bs21 speakers only cost me $40 at newegg because it was a black friday sale. I was going to save for the Hsu Stf-2 subwoofer which I could get in a few months and that would likely solve my problem for now in addition to using a fan. When I save even more money I can sell my pioneer set and buy some more efficient speakers.
