Here is an overview of my audio equipment, I've built most of it myself making it a lot cheaper then buying pre-made equipment. My sound system is always in a prototype stage I tinker with it the entire time I'm using it. I eventually want to start a business selling equipment and speakers using modular components so people can buy it one piece at a time. Ex: sell speakers with excellent drivers but ok crossover and then later offer a crossover upgrade.
