In the past I did a review on Acoustic Isolation Foams that sit under the studio monitor speakers that claimed would affect the lower end of your speaker audio spectrum, to make it sound tighter, by eliminating audio vibrations passing to your desk and into the room.
Well, I don’t like to rely on my ears for the results, as I had done previously, and wanted to do a real ‘scientific’ way of testing.
Watch my test experiment and find out the result and you be the judge. Would you trust your ear or the measuring equipment?
