IsoAcoustics Aperta 200 Plate

IsoAcoustics' Aperta stands allow your speakers to deliver clearer, more open sound, but they don't always fit on top of smaller surfaces, like the top platforms of some speaker stands. Use these sturdy metal support plates under your Aperta’s stands to provide them with a larger surface area for mounting. They attach to the top of your speaker stands or other support surfaces using the included double-sided tape, or can be drilled and bolted into place.
