I was looking at av123 and saw that soon they were releasing their X-Statik speakers.They are going to be 800 a pair. They have 2 6.5 in a sealed box and two more and a tweeter in an open baffle.
http://av123.wetpaint.com/page/x-statik What kind of different sound does an open baffle give, or am I going down the wrong path with this design.By the way, I will eventually phase out the polk bookshelfs, so I am starting a new set.
