I guess listening to it after my $1500 sub was a bad idea. I had to downgrade my Miller & Kreisel MX-200 because I needed the money. I bought this sub in good condition off craigslist for $70. At first, I wasn't too happy with it because just an hour before, I was listening to $1,500 quality. But after testing it out on movies and some of my music, I was pleasantly surprised how how deep this little bad boy got. Granted, it won't hit those low bass tones say a $500-$1000 sub would but for the money, it is plenty deep. The bass is clean, deep and hard hitting but I found it to be a little punchy compared to my Paradigm & Energy subs.
