I placed a card in each of my speaker crossover compartments. My speakers have a nice compartment in the bottom of the speaker ..... not inside the bass cavity which is a great thing! It has been 3days and the results have been very good. More “at ease” sound that is boxless with the speakers disappearing to a great degree.
My next eCard set is going on the back of each driver near the voice coil and drivers connection tabs.
