| basstraps cylinders tuned I've never seen this before so I was thrilled, and I wanted to show you how did this type of basstraps are made or at least are being made for my studio
it is a large cylinder (paper) with a hole in the lower end of a specific diameter, then a smaller plastic cylinder with a certain length and diameter (so it works with the appropriate frequency for each room) is put inside the larger one in that lower end, very cool stuff
all of the length and diameters for the cylinder were calculated (god knows how) by the acoustic treatment designer, all I can do is trust the mo'fo he's pretty good and he's a great guy
here is a sequence of pics of the assembling |
