Guitar and bass cabinets: everything you need to know (Part 1/2)
Hello and welcome to this week's article!
This time we talk about guitar and bass cabinets: what is the best choice for us?
A guitar or bass cab is a box shaped enclusure in which one or more speakers are placed, and they are the output device from which we can drive the sound of our amplifier.
Guitar cabinets can come standalone or as Combo, meaning that they incorporate also a preamplifier and a power amp, making them a single, portable solution for the musican on the go.
A cabinet can come in many different shapes, and during the years producers have become very creative, proposing alternative, lighter versions, but for this basic article we are going to focus on the classic type, which can be straight (a cube or parallelepiped version) or slant, meaning that becomes thinner on the upper side to save some weight and direct the sound not only on a straight line but also towards the ears of the player.
Usually a guitar cabinet has one, two or four speakers, according to the needs (not everyone wants to carry around a big, heavy 4x12, but sometimes on big stages it is really helpful!), and the speakers can be set in two horizontal rows, to be as space effective as possible, or in some 2x12 they are placed diagonally, in order to achieve the opposite result: to have as much room possible for each speaker.
Cabinets with two speakers can be engineered to give their best when put horizontally or vertically, but most of them can be placed in both positions with no difference.
Every kind of cabinet can have the back panel open, half open, closed or modular.
A closed back cabinet will have more sound waves bouncing inside, summed up to the one projected from the front of the speaker, and this will result in a darker, more bassy tone, while open back speakers will have more sound diffusion, and this will produce a more "open", highs oriented sound.
Half open back speakers tries to achieve a bit of the two effects.
Cabinets can be built in various types of wood too, and although many claims that it can affect somehow the final sound, I am not sure about this, as I have never noticed huge differences.
Another variable is the size: smaller , thinner cabs are lighter and easier to carry around, but will provide a slightly thinner, more highs oriented sound, compared to those with the same speakers but larger in terms of depth (which is measured in liters).
