The pair of small Foam Speaker Platforms from On-Stage are for decoupling studio monitors from their workspace. They offer to isolate the true tone and frequency ranges during playback of recordings in project studios, mix rooms, broadcast TV facilities, and more. The speaker platforms will accommodate studio monitors up to 6.5" in width and 11.5" in depth and prevent bass frequency build up from the hard surfaces of your desk. By creating separation between the speakers and the work surface, musicians and studio engineers will enjoy a more accurate audio picture of their recordings.
