Regarding Subwoofers

I love my Velodyne but this new technology looks interesting check out
Post removed has removed the pricing now and are asking for interested parties to request pricing. I read through the Tech Paper: it was a simple review of existing technology and the issues that engineers have to deal with. Issues I never really considered before reading this paper. This new driver seemingly eliminates the components that cause the issues namely the spider and surround. The company also claims it to be highly efficient only requiring 250 watts to produce a very substantial output.
