How to care for the speaker

Although the fabric part of the speaker has water repellent treatment applied, you can use the speaker more comfortably and for a longer period of time by following the maintenance procedure below.

  • When the speaker surface is soiled, immediately wash off the soil with fresh water (tap water, etc.). Leaving the soil on the surface will cause the fabric part or the passive radiator section to discolor or deteriorate, or cause the speaker to malfunction.


    • When salt, sand, etc. is stuck on the speaker after using it on a beach, pool side, etc.

    • When the speaker is stained with foreign substances (sunscreen, suntan oil, etc.)

  • If the speaker gets wet, wipe off the moisture using a dry soft cloth immediately. In addition, dry the speaker in an airy place until no moisture remains.

  • The sound quality may change if water enters the speaker or passive radiator section (). This, however, does not indicate a malfunction. Wipe off the moisture on the speaker surface and leave the speaker on a dry soft cloth to let the water drain out from inside the speaker. Then, leave the speaker in a well-ventilated place to let it dry out.

  • If the surface of the speaker gets dirty, do not use detergent, thinner, benzine, alcohol, etc. to clean the speaker because it will affect the water repellent function of the fabric part of the speaker.

  • Especially in cold regions, be sure to wipe off the moisture after using the speaker. Leaving moisture on its surface may cause the speaker to freeze and malfunction.

  • If particles, such as sand grains, enter the fabric or other part of the speaker, remove them with care. Never use a vacuum cleaner or an equivalent for removal as it may damage the speaker or other unit.
