What kind of wood is the best to make a subwoofer speaker box?
The wood will make little difference – however softwood -pine will absorb a little more and hard wood -oak will bounce a little more. Most likely nothing you will hear. However internal to the speaker box there can be padding and baffles (sloped wood slates) these will cause a wide change in the sound output. Also the backboard to the box will cause sound to change, cheaper sets tack thick cardboard or particle board over the box, a thinner real wood will give you a better sound. I recommend MDF though , have heard online many people use this. Try researching on line how to build a speaker box. If u live in the US, You can Try Home Depot, people there may also help u on the Spot.
