You've invested in a pair of high-quality studio monitor speakers, and you can't wait to hear what your music really sounds like. So you place the speakers on a desktop, mixer top, or speaker stands and... yikes! Vibrations and resonant energy travel from your monitors to the supporting surface as the speakers and surface acoustically couple, resulting in unwanted coloration and reduced clarity. Fortunately, you can easily fix the problem with a set of PreSonus ISPD-4 isolation pads. These inexpensive foam pads isolate your speakers from their supporting surface, reducing vibration and improving clarity and midrange resolution.
