Chashint - The Velo is made for 30 Hz and up bass. It's the type of subwoofer that will always sound good, and it is going to be easier to set up than something like the Hsu with the Turbo - or even the Hsu using one port.
The Hsu and Outlaw will hit deeper, and are both better overall perfomers, but they won't be as powerful in the 30-80 Hz as is the Velo.
A subwoofer that gets the 30 to 80 Hz range done powerfully is the type of subwoofer that most people will love to own.
Hobbyists such as one will usually find at The Shack will normally want the 20 Hz bass, and will typically look at the ID subwoofer brands for this.
