  • AP Application Note- Loudspeaker Measurements

    Something dropping in my inbox today, I saved the link that you would otherwise have to fill out a form about your business to get. It's a good primer on acoustic measurements.

    I got one too, it was from Audio Express, I subscribe to Voice Coil so think it was from them, and yes it is an excellent paper. good that you posted it could be of help to people.

        You can use a lazy suzan marked with angles. I do the poor man's method, print off a polar chart and tape it to the floor, then line the baffle of my speaker up on the chart for various angles.

          I made a pedestal which lifts small speakers up 3 feet, and another on which lifts them up 6'. These each have a hole in their base which lines up with where you'd put the baffle. I then use a bolt to connect these pedestals to a 2x2 piece of mdf which has angles marked on it. Works ok.
