Hey all, I have to do a project for my sophmore engineering clinic at Rowan and I chose to do it on making a speaker cabinet designed for a working musician who may face a large variety of sizes of gigs, while still accomadating to limited stage room. My plan is to design a 2x12 speaker cabinet with a switch from 4-8 ohms and fit easily in the back seat of most cars. The technology of the switch is what I will be doing the majority of my research on, and so far all I have found on the subject is the Epifani DIST system, the failure of the Accuswitch, and I heard rumour of a a similar device in a Mesa cab.... I've read that the dual voice coil has an effected high frequency range because of the extra weight on the speaker, so I'm also looking at any other solutions. Couldn't a large resistor be hooked up so that when the switch is turned to 4 ohm, the resistor will run in series with the speakers? My question to you is if you have any knowledge on this subject or links to any helpful articles, put em up!
