Hi folks, Does anyone know what bass/mid drivers interchange between different models of Castle speakers? I have a Tay with a broken driver, circa 1997. When I bought them a friend bought a pair of Isis that looked identical but with a smaller cabinet, and when I see pictures of Harlechs and Keeps they look like the same drivers again. I'm thinking another pair or broken ones might provide the part I'm after. Am I being too simplistic? Glenn
