Overview:
This is a calculator for designing a Single Fold Off-Axis Transmission Line Enclosure.  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.
The calculator does NOT take into account the effects of placing the enclosure into the listening environment.  This type of enclosure may not be the most suitable option for your application.  I recommend reading the articles in …
