I have (2) GK 212 neo cabinets. I will be trading with a friend tomorrow, I will be getting rid of one of the cabs. They've both been sitting in my basement for a few months, I opened both up just to inspect and to clean dust out, etc. I noticed both cabs had two totally looking drivers. They both seem to be NEO and both have the same numbers printed on the paper part. Did GK change the design? Are these even Gk drivers? Out of the two, which one do I want to hang on to. The all black one on the left seems to be a bit heaver but heavier duty. Any advice is appreciated.
