   What makes a folded horn go low? Is it the chamber size? length of the horn? Been looking around on the internet and there's all different answers which there most probably are but none say exactly what makes them go low
cheers

	If you're getting multiple answers you're not reading the right theory! And probably listening to what people feel is right rather then the maths. You've left off another important bit of theory which is expansion coefficient. I.e. exponential horn, conical horn, linear horn? All of these variables act together to get the final response and if you define 2 then the other becomes fixed. (Ignoring rear chamber, compression ratio, porting etc) In simple terms: Horn length is the key to cut off, mouth area is key to getting a flat response down to the cut off. Expansion coefficient depends on how you define those. https://www.grc.com/acoustics/an-introduction-to-horn-theory.pdf is probably the best article on the net in regards to covering the basics of horn theory I have found. Understand that and you are getting somewhere. Edited by odc04r - 18 April 2015 at 1:44pm
