ohhh the HSU is more. Well, that changes things, sorry
go velodyne then
I has a remote, front ported (if its going in cabnets and such) plus I like the sound of front ported subs, and damn sexy looking. Even though the velodyne is giant, its looks nice, making it acceptable for being in the open. It also has DSP presets (Movies, Rock/R&B, Classical/jazz, Games) for changing the digital EQ.
If you know this, then go ahead an listen to them. I have only heard the velodyne, but its you can get it cheaper then the HSU, grab it (it's 1100CAD up here)
