At the heart of the Solan bookshelf is a 1-inch (25mm) soft dome tweeter fitted with a neodymium magnet system. This driver’s smooth frequency response and lack of high “Q” (sharp) out of band resonances provides a very natural response to the high end. The bass/mid driver consists of a 5-inch (130mm) driver equipped with a large ferrite magnet driving a lightweight composite paper cone.
