IsoAcoustics GAIA Mounting Plates

Yes, these mounting plates are required for specific B&W Nautilus and Diamond models. They provide the necessary threaded interface to securely attach the GAIA isolation feet, as the factory-installed hardware on these speakers is not compatible with the GAIA thread sizes.

No, these plates are specifically engineered for the D1 and D2 generations of the Diamond series and the Nautilus line. If you own a D3 or D4 model, you should check the IsoAcoustics compatibility tool, as those speakers often require different mounting hardware.

Not at all. The plates are designed to replace the existing factory ball-casters or spikes using the speaker's original mounting points. You simply unscrew the factory hardware and bolt the plates on in their place.

The plates themselves are simply the interface that allows you to install the GAIA isolation feet. The actual sonic improvement—such as reduced vibration and tighter bass response—comes from the GAIA feet, which these plates allow you to mount securely.

These are typically sold as a set to accommodate a single speaker. Since you will need to equip all speakers in your setup, ensure you purchase enough sets to cover the total number of speakers you intend to isolate.
