WHAT'S MY RBH SOUND MT5 SPEAKERS WORTH

I Have a pair of rbh tower speakers. They are very heavy. Each speaker has 2 (10") subs, 1 mid, 1small horn, 1 dome tweeter. They are in excellent shape. 44 in tall, 14 in deep and 12 in wide. I can't find anything out about them. I've looked everywhere. The only thing on the front is a tag that says SOUND T and on the back is a sticker that says MT5. If anyone can tell me anything about these I would really appreciate it. Am trying to find out how much they cost new. What they might be worth. Power handling. Any info will help. Thanks
Danny
