We’ve rounded up as many plans as we could find to help you get started with something that interests you. We’ve included pictures as well as a short description for each one, so you’ll know what you’re getting into before you start.divider 4

Guitar Speaker Cabinet Plans

1. Marshall Top Cabinet

The Marshall full stack is one of the most popular amplifiers of all time, used by many greats, including Jimi Hendrix and Eddie Van Halen. This plan shows you how to make the top half and will provide you with plenty of power with room for four 12-inch speakers.

2. Marshall Bottom Cabinet

This project is similar to the last one and shows you how to build the bottom half of a Marshall full stack amplifier. It’s not difficult to make and is perfect alone or combined with the top half. This cabinet has room for four 12-inch speakers.

3. Practice Amp

The Practice Amp project walks you through creating a practice-sized speaker cabinet that will also house the electronics section. There is enough room for a 12-inch speaker, great for a basement or attic rehearsal rooms. It’s not hard to build and results in a durable and attractive amplifier.

4. Rehearsal Amp

The Rehearsal Amp plan is a two-speaker design that uses two 12-inch speakers to create plenty of sound. This size amp is perfect for playing along with drums and is big enough for most small clubs.

5. The Tall Boy

The Tall Boy is another design that uses two 12-inch speakers like the last plan but places them in a vertical position instead of horizontal. This position helps the sound project out a bit further and makes it easier to transport, especially if you put wheels.

6. TRM Guitar Cabinet

The TRM Guitar Cabinet is like the last design but removes the slanted face in favor of a straight face design that’s easier to build and resembles traditional house speakers. This design also utilizes large handles for easy transportation.

7. Large Practice Amp

The Large Practice Amp is a design that uses two 10-inch speakers for more possibilities and louder volume. The two speakers allow you to use stereo effects with the amplifier like stereo chorus or ping pong delay to give you a thicker tone than is possible with a single speaker practice amp.

8. Angled Rehearsal Amp

The Angled Rehearsal Amp is similar to our last example, but it increases the two speakers to 12 inches. This design results in a squarer shape than is possible with the side by side or top and bottom plans.

9. 3D Practice Amp

The 3D Practice Amp is one of the more complex designs on this list. It uses intricate wooden bracing like acoustic guitars to improve the tone and shape it to better suit the guitar. It uses a 12-inch speaker and an open back.

10. Eminence Cabinet

The Eminence Cabinet is a four-speaker cabinet similar to the Marshall Bottom Cabinet we mentioned earlier but is slightly more complex to build. It features a center port for better bass response and large side handles.

11. Ashen Custom

The Ashen Custom amp features a vertical speaker design similar to others on this list but uses advanced woodworking techniques to create a composite material to make the cabinet. The composite of different woods is extremely attractive and will look great in the home or studio.

12. Contemporary Cabinet

The Contemporary Cabinet is a unique design that adds space for a horn tweeter for a higher fidelity sound. This setup is especially good if you use a looper pedal or play along with samples, and there is more sound coming from your amp than your guitar.

13. Contrast Carpentry

The Contrast Carpentry speaker cabinet uses an unconventional material as a housing material. Instead of wood like most others, this cabinet recycles old flight cases that house electrical equipment and microphones during transportation.

14. Combo Package

The Combo Package is a combination speaker cabinet and amp head. The speaker cabinet houses a single 12-inch speaker, while the head will support most class A and B tube amplifiers, as well as most solid-state amps.

15. Studio Amp

The Studio Amp is an attractive speaker cabinet that will require a little extra skill due to the fancy finish and composite design. This cabinet uses a 10-inch speaker that’s ideal for recording because it lets you crank up the amp while staying within manageable volume levels.divider 6

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.divider 1


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.
