here is my craigslist ad http://cleveland.craigslist.org/bar/3200456215.html I've never used a sub with this setup as I never really thought it needed it if you equalize it right. It has plenty of connections for more speakers as well as a sub out I believe. Its a nice entry level budget setup, I just don't have the space for the large speakers where I've moved so I'm wanting to sell to get some bookshelf speakers
