I haven't listened to it, but it did show up as one of the top 3 subs in it's price range. I don't remember which magazine though. I was reading, Sterophile, Perfect Sound, Sound and Vision, etc. All the magazines in that section at Barnes and Noble. The Def Tech ProSub 100TL was number 2 next to the Paradigm PDR-12 in its price range.
Just a follow-up. I saw the magazine on the Super Cube again . It was The Perfect Vision. Also it wasn't in the top 3, it was the "best buy" in it's category. It stated it hit the mid 20's very well.
