chesseroo and JohnK: Thanks for responding. I frankly became alarmed a bit when I looked at the performance ratings. Both power rating and frequency response to ME aren't what I thought they should / could be. Ok, so I won't worry about it. Just a little disappointed. Yes, the fact is I would be doing myself a big favor by purchasing a couple subs for the other two channels to take care of the sub levels. It's amazing the difference of comparing the subs in my Buick to the woofers in my home system. But then again there is no comparison. Two different applications altogether. Thanks Kedoba2104
