ah I see..yes I could see that being the reason. I will hook up my older amp to it an see if it is the same thing. however.. While they are very sensitive I cant help the fact that in my room it just doesnt sound so loud..another wierd thing is too..i can tell the woofers have a distinct sound from the material they have on them..whenever theres like a kick or something, it makes a noticeable plasticy sound.. Whether it be loud or quiet..on both speakers. And ive never pushed more into them than they could handle. Its been like this from day 1..
