Original publication: Part of the design, production and technical information related to the IMF Reference Standard Professional Monitor. |

Portion used |
Entire diagram |
Low resolution? |
Diagram used to the minimal extent needed to show useful features, and no further diagram used to show other features. No benefit to reducing resolution as this is a technical line drawing not a photo, so any resolution showing useful detail will also be effectively equivalent to a full version. |
Other information |
Company has closed long ago, design was published and available to the public by them openly and freely for decades before then; and it is unlikely that any meaningful residual commercial value lies in the visual appearance cutaway diagram. The diagram is insufficiently detailed to allow reproduction of the speaker, and reproduction would be the commercial opportunity. |

Purpose of use |
It illustrates the complex nature of transmission line deisgn of an actual product, by one of the "great names" in that field, who dies in the 1990s, from a product of his from the 1970s. |
Replaceable? |
Transmission Line speaker designs are highly specialized and very few people in the world have produced them in actual proiducts. Those that did were mostly active during the 20th Century and the companies involved have closed and their designers are deceased. It is unrealistic to expect that a verifiably valid design of how an actual product would be created, would be accessible other than by using a diagram of a product by one of those few companies in that era. A "mockup" by an amateur or a theoretical diagram would be likely to misinform, or at the least fail to convey the true nature of such a design as executed in an actual product. |
