To make sure you're hearing your monitors and not the room vibrating with them, these are a great idea.
Many people ask if these things really work, or is it just a bunch of snake oil...Well, the answer is "Yes, they do work".
It's not a drastic change in how your monitors sound, but rather a more subtle reduction of resonances in the middle-bass region, which in turn gives you better clarity in the midrange. With the MoPAD's in place, you will be able to judge your mixing decisions with more accuracy and confidence.
They're 12" long and 4" wide and support up to 100 lbs.
One package of MoPADs isolates one pair of monitors and includes four isolation pads (two per monitor).
