I knew that once I mentioned their name, I would get that question :-) There is no model number on the speaker. For some reason, I am thinking AR303. They are 24" X 12" X 10". They were a very good speaker in their day, for the average music lover. They cost me a $1,000.00, 15 years ago. Every other electronic product has dropped significantly in that time. However, I notice that home audio is the exception. Who buys 10 to 50 thousand dollar speakers??? I can't imagine, with pop or rock, there being that huge a difference.
