Paul, The resonant engineering XXX 18" is much like the Adire Audio Brahma, except bigger!! I've been posting the build up kinda step by step on Soundillusions.net (where I picked the XXX up)...I'm sirsloop on that forum. Heres the working link to the Project XXX thread. http://forum.soundillusions.net/showthread.php?t=28471 If you guys want to just see pictures of the build up you can visit my site at http://www.87gt.com/XXX . I should have the driver installed tomorrow and playing. I need to finish up the top of the box, paint it, and install some t-nuts.
