Ohm C2 Woffer Replacement

I picked up a pair of Ohm C2’s last week in which the drivers have blown. I have another pair of these for which I ordered replacement drivers about a year ago ($145 each). The performance of these speakers is very good, but not great. Wondering if using a woofer (10”) from another manufacturer would be worth pursuing. Is anyone familiar enough with these 6-Ohm, 88dB C2’s to recommend alternative woofers? Appreciate any input.
Ohm is usually tight-lipped about which drivers they use. You might be able to determine the model with some searching on the Internet and find a substitute/upgraded driver.
