Not to discourage you, but it took me 2 years to find 2 sets of walnut Forte II. So keep scouring the rags. I drove 10 hours round trip for 1 pair but it was worth it. They make a great surround system.
Good day off Craigslist; a SW-10 II, 2-KG5.5, 2-KG 2.5 and a KV1 for a Grant. They are a little rough due to being stored in a shed but they all work. I am listening to the KG 5.5 at the moment.
