Hello all. I'm trying to find out what I have here. I know for sure the amplifier was made by CMI, and that it looks to be a combination of the G100A and G100B amplifiers. The two 10" drivers up top are in a sealed enclosure, and the single 15" is ported. I am unable to figure out the manufacturer of the alnico speakers, but they are all from the same manufacturer. I am just curious if this is some sort of one off mutant, or if there is actually some documentation out there I could look at. Thanks for helping the newb. I'm not sure how to resize my pics to potato resolution so they can be uploaded here, so I will add them below as I figure this out.
