Unknown speaker unit
I attended an auction a couple of days ago, and I bought a box full of stuff from a Danish company who had been working with sound systems for electrical cars.
Among screwdrivers and electrical wires, I found a bunch of small speakers, but I can’t figure out what kind they are since there is no information printed on them.
I know that they are produced in 2012 and they are 3” (probably) full range speakers with Kevlar cone. I have measured them to 4 ohms and I guess they are around 20 watt, because I have tested them on my TDA7492P 50W+50W Wireless Bluetooth 4.0 Audio Receiver Digital Alibier Board with no problems at all.
I have attached some pictures of the speaker. Can any of you recognize this speaker and maybe tell me a little more about them?
