This is my current project, a dual Adire Koda 10 sub cabinet. The unit consists of 500 watts of power being delivered to the amazing Adire Koda subwoofer. The XBL2 topology exhibits less distortion than any other motor design in production today. Wrapped in Ribbon Mahogany, sealed with tung oil it is musical, accurate,and dynamic, with unparalelled transient responce and extention.
