What are you waiting for? If you have excellent Studio Monitors and have them sitting on your desktop, piles of books, monitor stands without isolation pads then you're probably dealing with resonance and noise! Get some of these babies under them monitors and get back to those mixes! Clarify your sound. 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. One set fits all.
