Looking for information on a replacement speaker for Conrad Johnson Synthesis SRS 10 in. Woofer


Hello All,
I have a rare Conrad Johnson Synthesis Reference Speaker System. Consist of two mid towers and two Sub towers. Each Sub tower consist of two 10 in. woofers. Can't find any info on the woofer. Only numbers on it are SP101 1036 8719
If anyone has any info or recommendations that could point me in the right direction, it would be greatly appreciated. The tower is ported, but doesn't appear to have a crossover(woofers are full range???)
Thanks in advance.
