This is for a single speaker. I had matching 3 speakers for the front and have sold a pair and now have the one Reference 3.1. speaker I was using as the center.
If your theater or multi-ch music room allows it, this is the best way to create the perfectly seamless sound field for your front channels (if you already have the 3.1s, obviously).
The speaker is in mint condition and as you can see in the pictures, in factory original shipping package ready to go. The shipping and paypal fees will be paid by the buyer.
