It's a 4" driver.
"20w nom - 40w max 4 - 8 ohms" written on the shredded back label along with "patent pending". 6 spoke stamped basket. Inverted orange foam surround. Paper cone (I glazed it with nail polish a long time ago, hence the shine). The dustcap is a piece of chromey plastic. I really like the way the driver sounds and if I knew what it was or what brand made it, I could buy a match for it. Thanks.
