A suggested cabinet is Radio Shack's part number 270-253. The soft aluminum is easy to drill or punch. Since the panel controls are not PCB mounted, it is possible to make the panel layouts of your own design. For convenience, you may choose to use the layout supplied with your kit. A cabinet kit is also available, featuring painted and silkscreened front and rear panels.
All hardware is included with the cabinet kit.
A n option of the audio filter allows you to select the degree of peaking and select a center frequency other than the popular 750 to 800 hertz if desired. Some prefer a much lower tone, somewhere around 650 hertz. The audio filter enables you to pull the weak ones up through the noise, and eliminate adjacent interfering audio tones.
