[Rectilinear Full Range?]

Thank you for the response. I have Mini iiis and was wondering if the Sound corporation was possibly an offshoot. 

Always something to learn. Thanks again.

Robert helped me on a restoration online, he was so generous with sharing his knowledge. 

RIP, Robert.

I’ve had Realistic Minimus 8s on a shelf for a while and decided to open them up and check drivers
 

I was surprised to find Rectilinear Sound RS-406 drivers. I guess they were installed by a previous owner. 
 

I’m coming up short on a search for information on these. Any help to point me in the right direction would be much appreciated. Thanks.
