fair price for Avant Garde Duo 2.2

Can Audiogon members suggest what they think would be a fair price to ask for my pair of Avant Garde 2.2 speakers? They are a demo pair I bought from an audio store in Illinois and so I have been the only owner. I have new neighhbors in the neighboring condo next to mine and so my days of enjoying the full potential of these great speakers is over.
