Been quiet for six years. Pull your tweeter and post pics. It could be JVC made, or from a supplier they used. These look like they were part of a rack system setup. I looked them up, and generally most state bass is good, otherwise average consumer grade speakers. You could probably improve the sound with better mids and tweeters. Once you know their specs, look for better drivers. Also, post some pics of the cab interiors. Their construction quality will tell you a lot.
