Essential Features of a Guitar Speaker Cabinet

Size and Shape of Cabinet

The size and shape of your guitar speaker cabinet can vary considerably. Most amps are square or rectangle and are generally wider than they are tall, though there are several exceptions on our list. It can be a simple box but will often sound better if you spend some time learning about wood bracing and ports to tune the amp to reproduce guitar tones better.

Size and Number of Speakers

Most guitar speakers are 12 inches wide. However, plenty of brands use smaller 10-inch or 8-inch speakers on studio or bedroom practice amps. You can even find smaller speakers on battery-powered portable amplifiers like the Pignose.

If you use your speaker cabinet in the recording studio or for practice, we recommend a single 10-inch or 12-inch speaker for most people. If you use your amp at rehearsal or for live performances, you will want one or more 12-inch speakers, depending on how much space you need to fill.

Many two-speaker amplifiers have built-in digital effects processors that create a stereo image. This effect can make your sound much fuller and wider than is possible from a single speaker.

Other Components

Most speaker cabinets will require you to attach a “head.” This component is responsible for amplifying the guitar signal and contains the electronics to do so. Combo amps have the electronics built into the speaker cabinet. Most professionals prefer the two-piece design because it allows them to mix and match for more tonal variety. However, if you are only building one cabinet, you might choose to make one that combines the electronics into the design.

If this is the first guitar speaker cabinet you will build, we recommend something easy with a single speaker and does not contain onboard electronics. Once you have some practice, the larger cabinets will provide you with a lot more volume, and experimenting with wood bracing, insulation, and bass ports will help you tune the sound.
