These are rare old school midrange with faded markings lika a hard to read serial number and made in Germany logo. I’ve run these in my rear doors with some Jl audio ZR 6.5s upfront. These sing! Are loud and clear and more than held their own with the top tier JL ZRs, was never disappointed while running them. They date all the way back to the 90s and still play great! They just don’t make them like this anymore.
