Click on buttons below for quick box-port sizes! Results are for maximum flat response. The calculations were based on Ray Alden's "Advanced Speaker Systems" pgs. 41-43 & Vance Dickason's "The Loudspeaker Design Cookbook" pgs. 47-50

This is my first speaker project. It's a tapered transmission line speaker. The design is by David Weems.
The center channel speaker is of my own design using 4" fiberglass drivers and a 1" silk dome tweeter all from MCM Electronics in a MTM arrangement.
The self powered subwoofer is sort of a kit from from MCM Electronics. They had a special on the woofer/crossover/terminal. They also sell the box to complete the kit. I later added the amp, also from MCM Electronics
