Part I: Building Broadband Absorber Panels
Background:
After reading Ethan Winer’s articles and information from Auralex Acoustics, RPG , Jon Risch’s great DIY site and the enlightening Ethan Winer: Acoustics Forum at Music Player Network, I decided to build a modified version of the 703 2’x4’x4” panel bass traps and then two “Super Chunk” Corner Bass Traps. Initially for the panel traps I planned to build a wooden frame as others have done.
But after reading Ethan’s “Real Traps – Measuring Absorption and the Numbers Game” article I decided to attempt a design more resembling the Real Traps frame. My goals were to build a light yet strong frame and to simultaineously maximize the amount of absorption on the 4” sides of the trap by not using a solid wood frame. Of course at a DIY project I also wanted to to build the traps as cheaply as possible.
