Hi folks. I've just acquired these C37 and looking for some input. They have an odd load it seems, in the 14c. I'm wondering if the port cut in the baffle is tuned to the 14 or if they came with a standard cut out? It seems there is an adapter to fit the 14 and I was thinking it would be nice to fit an 001 system but maybe not if it is tuned to the 14. Thoughts?
