Best Studio Monitor Isolation Pads

Isolation pads are sold by the driver diameter of the speaker they sit under, not by the size of the pad, and that labeling is the whole decision. The three common bands are 3 to 4.5 inch, 5 inch, and 6.5 to 8 inch monitors, and the match has to be to the cabinet footprint rather than to the marketing size: an 8 inch two-way with a deep cabinet will overhang a pad cut for a 5 inch monitor, and once a corner of the cabinet touches the desk the decoupling is gone and you have paid for foam that does nothing. Density is the second thing to read. High-density acoustic foam is the phrase to look for, because open-cell packing foam compresses under a 15 to 20 pound monitor within weeks and then transmits vibration straight into the desk again; a pad that has visibly flattened is finished. The audible effect is not subtle bass extension, it is the removal of the boxy 100 to 250 Hz smear a desk adds when it is being driven like a soundboard, which is why pads help most on a desktop and much less on a proper stand. Tilt is worth having if your monitors sit below ear height, since the reversible wedges let you aim the tweeter at your head instead of your chest. Pads ship in pairs; a single-pad listing means you need two.
