Hey this might be a dumb question but i have not found any good responces. If someone puts dynamat inside a box will it decrease the sound output of the enclosure? Common sence says yes, but i am uncertain of the results? Any answers are appreciated thanks

What do you mean by "decrease the sound output from the box"? Using vibration dampening materials inside an enclosure will not change the SPL from the woofer.

Really? I fiqured it would dampen the sound and decrease the spl? Do you know exactly what it will do?

Thanks for the help.

It can help make the enclosure more solid and acoustically dead, thus increasing SPL (potentially, depending on the quality of the construction.) Using sound deadening material inside an enclosure is very common.

No, Dynamat will not decrease the output of a box.
