Caution!

Disconnect your amplifier/receiver from the power supply before connecting your speakers! Refer to the amplifier/receiver's user manual for instructions on connecting speaker cables.

Care and Cleaning Tips

Caution!

Improper handling of the speaker may cause damage.

• Ensure that all connections are correct, there are no short circuits, and the speaker is completely dry before resuming operation.
• Do not use harsh cleaning agents or solvents such as gasoline, alcohol, or similar substances!

Housing

We recommend using a standard glass cleaner sprayed onto a cotton cloth. This allows most fingerprints and dirt to be removed easily. Alternatively, you can use window active foam. We advise against using microfiber cloths as they may cause micro-scratches on the surface.

Membranes and Speaker Drivers

To remove dust from a speaker driver, use a lint-free cotton cloth and gently wipe the membrane with very light pressure. All Nubert speakers' tweeters are protected by a grille, which can also be wiped lightly with minimal pressure. If the dust cannot be completely removed, a makeup brush from the drugstore can be used.
