iso acoustics aperta isolation stands
ISOacoustics Aperta isolation stands are designed to fully isolate bookshelf loudspeakers weighing up to a maximum of 15.9kg up to 34kg each from vibrations caused by the resonant surfaces they sit on transferring vibration back up to the loudspeaker. The result is improved focus, soundstaging, and detail.
They also provide a lift in height for a loudspeaker, which reduces higher frequency reflection from the surface it is sat on, and can also be used to provide tilt, either for when the speaker is positioned lower than the listening level (or higher), or further reduce HF reflection.
They're really one of those products that you don't need to say much about, you just have to hear them in action to appreciate the level of improvement they can bring to any system.
