Sorry to hear about the damage. There were two versions of the 901 VI speakers - v1 and v2. Only the 901 VI version 2 equalizer can be used with the 901 VI v2 speakers. Outside of that, you should be fine with replacing the speaker with an identical unit. If you'd like further clarification, please feel free to post images of the system, but in line with our Community Guidelines, please do not share your system's serial number.
This isn't a component that we currently retail and sell due to the age of the system, but we may still have repair options available to you, dependant upon the seriousness of the damage.
