This is a vintage loudspeaker could also be used as an external speaker or amplifier. This is an RCA suitcase style 16 mm rca400 loudspeaker. This is outfitted with an Olsen cone which is in very good condition. I don't see any dryness. This item has been tested and does work. It's an Olson loudspeaker approximately 8 OHM. There's also a good amount of cable that this works with approximately 8 ft. There is also two pieces that would go with the projector in good condition. The box is like a green wood handle is nice and tight to metal enclosures. Good inside paper sticker reads RCA 16 mm loudspeaker mi-1312 and is eight OHM is written in pencil. It is in good working condition. Cosmetically, there are some blemishes to the case. The front metal grill has some scuffs on the front that I have not attempted to get out. I will leave that to the restore. Thank you for looking
