I define 3 steps in horn design: 1) Horn design (math model); (PDF) Horn Theory: An Introduction, Part 1 Library Genesis 2) Investigate how to get a good response at low frequencies (30-50Hz) without the horn bell being 3m or wider 馃榾 (but the size of commercial models). The main focus is to increase the area of the flare at an exponential rate. The formulas used in the calculator create a design that suggests the most maximally flat response in an anechoic environment based on the number of drivers, the thiele small parameters and the allotted dimensions specified in the user’s input fields.
