Description

Klippel make a business out of those tools, i'd like to create a DIY version for home application in order to test loudspeakers and find their properties. The goal is then to create good loudspeaker even if you don't have any properties on your speakers. An application will be added in this project

Details

The project is divided in four main parts :

- Power supply + Amplifier : Managing high power tests

- Analyzer : Managing low power and high power tests

- Rack : Standardize this tool for classic chassis

- Software : Analyze results through sound card

A/ THE RACK

19" rack is chosen as standard in order to put it in a basic amp stage. My choice turns to MDF wood to build the chassis as it is easy to work on and it will break any ground loop as we will not use the ground cable in order to not create extraneous noise in the system.

The main chassis is MDF 18mm, front and back plates are 5mm plywood and top plate will be aluminium in order to mount a fan on.
