mid horn help

Ive not finished my current build yet but, Ive got the building bug!. I would like to further my knowledge in horn loaded mid speakers, and my question is, is there a formula to work out the rear chamber size for a new design build. ie, if i where to use a pd speaker (model a) the rear box volume would be!, or void etc. My second question is most wooded mid flares i have seen have a rectangleor square baffle opening. What is the advantage of having a round baffle opening like most fiberglass ones. Edited by: bee

Just make the enclosure on the back of the driver as small as possible.. that's all there is to it.




A mid flair ideally starts round and smoothly opens out to a square / rectangle... the wood designs are that way for ease of build, with fibreglass you can get closer to the ideal.

Thanks adam im working on a new design as we speak. Ill post my ideas up as soon as.

How do you calculate the correct baffle opening size for a horn!. Is it hit and miss or is there a formula. Sorry for all the questions, I'm just on a quest to learn.

Unfortunatly a formula is needed... You need to work out the compression you want at the throat.. If your using a phase plug this changes again... You should read Centauris website... I'll dig a link out for you when I'm not posting from a phone.

Hello sir, well firstly horn design is both similtaneously more complicated and also far simpler that you'de think. getting a grasp on it isnt quite as simple as a short post on a forum.
