Hi guys I just got a pair of cf-4 version 1 supposedly. ports are long. Made in 94. How do I tell if drivers are original. Starting to wonder about the guy I bought them from. One crossover wires are clear which I'm guessing are the monster wires making it a version 1 I believe. Other one is black and red for driver wires. From reading I think that's version 3. Wondering one if drivers are original and how to tell. Thank you. Could really use some help.
