You might not be aware how much the type of wood used for building a speaker cabinet greatly contributes to its tone. Cabinets, like guitars, can be built out of just about any kind of wood. But just like guitars, only a few kinds of wood are used because of their sound or cost. In this excerpt from my Ultimate Guitar Tone Handbook (written with my buddy Rich Tozzoli), we look at the most popular building materials used in speaker cabinet construction today and how they affect the tone that you’ll hear when you crank them up.
“Marshall cabinets are built out of 11 ply Baltic birch, a wood that’s known for its strength and light weight. This is one of the reasons (besides the speakers and the closed back) that nothing else sounds quite like a Marshall cabinet. Other manufacturers also use birch, but some use the cheaper and thinner 3 or 5 ply, which compromises the sound. Others use 13 ply birch to make the cabinet more robust in transport, but that makes them heavier as well (see the graphic on the right below).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
