Saw these at an estate sale. Anyone seen them before? I haven't been able to find anything on them. No clue either what the little one is. There is no name on it, but the grill cloth seems to match the speakers. postimg.cc/gallery/4kmD6mVv |

Given the multiple input options and the Rowe-AMI brand name, I’d say they’re on that list of extension speakers somewhere.

The big ones seem to be EX-201 like shown on the paper ID tags. www.jukebox-world.de/Forum/Archiv/AMI/AMI-EX-200.htm#EXI never saw the little one and doubt it is a Rowe product. My guess is that somebody did use the speaker cloth of EX-201 for a self-made unit. The knob outside and the extra board inside, could it be to increase volume directly at the speaker? |

Thanks. I'm far from an expert, but I searched the web here and there for Rowe AMI info (we have a JAL-200 we bought about 5 years ago), and did more searching after I saw these speakers. I never came across the website you pointed out. If nothing else, it gives me an idea of when they were sold. I bought the speakers. $65. My son was the push to buy them. He likes the more unusual, rare things and though since we couldn't find much info on them, they fit the bill. The guy tossed in the little one. |

Thanks for the link. Agree that the knob on the little one is to control volume level. Seeing that the ad you linked to shows paging systems, I'm wondering if someone made the little one and used it for that? |

That circuitry on the little one may only work if you use a 70-volt input. There's no photo of the input panel on that one so I'm not sure, but I don't know what speaker-level signal (other than 70 volt) could possibly do anything as complex as what that board looks to be! 70-volt lines are good at traveling long distances as well as having many speakers daisy-chained together (think dozens of overhead ceiling speakers at a store) without presenting a crazy load to the amplifier.
If you see a pushbutton somewhere, that might be the talk button for an intercom. A speaker can be used as a crude microphone, and crude is all you need with a paging system. Or humor. ;-)

Or humor. ;-) I don't have them here to take a picture, but the inputs are RCA jacks. I just noticed there are no wires running to the speaker driver. A loose white wire is visible. I don't see a loose black in the picture. I'll try to remember to look at it the next time I am near them (it all went into storage for now). The knob in the corner is the type that clicks off when rotated counterclockwise (can't remember what they call that). No push button for talking. I really didn't pay much attention to the little one since I wasn't paying for it. I just took it along with the two larger speakers. |
