For this project you’ll need the following materials:
Cigar boxes (same quantity as the number of speakers, and large enough to fit the speakers)
Midget louvers (approximately the same diameter as the speaker cones)
2 component epoxy
Low expansion foam (optional)
hole saw bit (same size and midget louvers)
other miscellaneous drill bits
Dremel tool with cut off wheel and router bit
scrap piece of wood
I used a few other tools not listed here for optional steps. The tools you will need may vary depending on the construction of the speakers you are using and how fancy you want to get with the mounting and wiring.
I already had the midget louvers for another project. You can purchase these online from construction suppliers. I got the cigar boxes on ebay for less than $5 per box. If you are a cigar smoker, this will give you an excuse to go buy a bunch of cigars, or a use for your empty boxes.
