Grant,
To place a Sistrum platform under a speaker like yours would require at least two people. The first step is to predetermine where the speaker sounds best and to mark that area. If the floor is carpeted I stand on the platform so the points penetrate the carpet and pad. With the help of a friend or two I would then place the speaker on the upper set of points. I would have on hand 3 APCD discs for each speaker to rest on. These offer surface protection but also in this case allow you to slide the speaker front to rear left to right and adjust for toe in. The discs before they settle in allow for a smooth surface for the speaker to be tweaked geometrically. This is important to match all the angles of say the left speaker to the right speaker. Some speakers sound better, different with or without the APCD discs engaged. They can be removed after the angles are determined. One at a time by tilting the corner of the speaker and allowing for the disc to fall away.
The platforms vary in their reactance. All 3 will improve your speakers. The speakers will sound better on the platforms from the get go. They will need to settle in as will your speakers. Vibrational drain will develop a pattern over time usually complete after 96 hours. Its very informative to hear this steady progressive improvement. Enjoy and if you have any further questions I will be happy to answer as I can Tom
