Hi there, I'm looking to source locally (Mexico) some foam and found a place in Mexico City that specializes in acoustic projects and products www.comaudi.com.
They carry eggcrate and triangular foam. The spec sheet says that it is polyurethane open cell foam with a density of 2 pounds per cubic feet.
Does that sound right/appropriate for speaker building?
which is better? Triangular? Eggcrate?
They claim that the eggcrate has the following coefficients:
250Hz 500Hz 1000Hz NRC *
0.31 0.73 1.04 0.80
Thanks in advance!
