Hi to all fellow inmates
I have a question about the rear loading of horn drivers. I've had this question for a while, but it has been brought to the fore again when looking at these photos of Miroslav Ivanek's DIY Hedlunds. It is this- what if the loading cavity behind the driver was large, before the horn starts. In the first picture I have indicated which part needs to be closed on the Hedlunds.
I have added the next two pictures just to give some clarity as to which area must be closed on the Hedlunds.

This is just an example. My question is what effect this would have, either on the Hedlund or any other horn desing is the driver saw a 'largish' cavity behind it before venting into the horn itself. Will this not allow lower bass, as well as allow less midrange to 'escape' into the horn. Opinions, ideas, anyone to try this?
Enjoy.
