Appreciate all the feedback everyone. I can get a SVS micro 3000 for about the price of the EP-175 after making a few calls yesterday. I have no idea if I can hear well down to 20 HZ. About 20 years ago, I used to rock 2 15s in the back of my car and loved the low frequencies.

I might pull the trigger on the micro 3000, but now I am wondering if I should get something a little bigger. EP 500 is really nice looking specs wise, but I have a hard time justifying to myself to spend that much money on a sub.
