JBL sub160 10 inch sub. Works like a champ and POUNDS! Look up specs online. I’ve seen several of these on EBay upwards of around $200. Asking just $80. It looks new except one small scratch on the inside of the port hole thingy (see pics). I was trying to sell it along with a package of awesome speakers and an amp. I have one picture of all that together and a separate ad if interested to see that. But also trying to sell things seperately now
