After a couple of year in storage, I have come to the conclusion that my musical tastes have changed enough so I am willing to part with my Imperials.  If someone else could use them, I would be willing to let them go.  I would like to get back what I've got into them, namely 10 sheets of 3/4" plywood (about $400).  They are empty cabinets, set up for dual 18's.  Here is a pic:

PM / email / post if interested.
