However, when I add-in a subwoofer, it is another story. I tried to borrow a few good subwoofers from my audiophile 'kakis' to test. They range from Celestion's own System 6000 to Hsu Research to Genesis to Velodyne. All of them did not sound good in my living room. They sounded either too boomy or too muddy. That's why, I am reluctant to buy a subwoofer.
