I have 2 speakers for sale, although they are rated for the same amount ohms, and channels, and the dimensions are the same 14" high by 7" wide and 7.5" deep, one is a series 3 and the second is a 4. Asking 5$ for the set. I've been using them as book ends, and after redoing my shelving I no longer need them. However, I've only ever used them as bookends, so buyer beware. Hope they work for you. Im in Sunnyvale and unfortunately I cannot transport them.
