This is another brand that I have never heard of. Very good looking driver's tho. Makes me wish so bad that I was rich! I would buy every single brand just to swap and try. This one specifically has interesting specs. The recomended sealed box is from 3 to 8 cubic feet! Ive never even heard of a sealed enclosure that large. So a major question this leads me to is which would hit harder and sound better, a sealed enclosure or an IB setup? I get so confused when people start talking about specs like Qes, Vas, Fs, Xmax.
