Shortening ports

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Its been a while since this was mentioned on the forum but has anyone tried to put a chamber in line with a port on either end. This should reduce the length of the port significantly allowing a reasonable port size without having it really long.

If anyone knows any technical papers on this subject I'd be interested to read them, its the maths for how to make it work that I'm interested in finding as well as any practical experience as to design or implementation.

	You can best simulate this in AkAbak. Use Hornresp to calculate a normal port assisted horn, export as an AkAbak-script. Then add a chamber and port between the normal port and it's radiator in AkAbak. Hornresp puts an easy schematic diagram in AkAbak, that makes visible what nodes you need to create and what numbers you can assign. Tip: Make all ports the same cross sectional area and non expanding to keep things easy at first. Best regards Johan
