This zine provides how-to instructions for constructing a basic, low-cost, highly portable (as in sling it over your shoulder) sound system for demos, parties, or whatever. A tried and tested method, but it surely could be vastly improved upon as the author is not an expert. This zine is excerpted from the Engineering Social Justice and Peace zine, (Re)Construct Vol. 3, available at http://esjp.org/zine. Send questions, pictures and other feedback to email@example.com.
