【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. *From October 2023, the panel thickness has been changed from 20mm to 15mm. Thank you for your understanding. This is an innovative self-made acoustic panel kit created to create the ideal room acoustics. Intended for audiophile listening rooms, instrumentalists, and recording studios. The Z103 acoustic panel is an acoustic panel that has sold more than 2000 sets since its release in 2012. By setting it diagonally on the back of the speaker, it increases the strength of the mid-low range from 80 to 200Hz, and diffuses reflections in the high range, preventing flutter echoes. You can download a PDF of how to use the product, including how to set it up for purchasers. We also provide setting advice via email. Acoustic Panel B can be extended in height to 600mm, 1200mm, 1800mm, or 2400mm by connecting them with metal fittings, etc., and can also be connected horizontally in 250mm increments. (Please purchase metal fittings for connection at a home center, etc. For vertical connections, please use metal fittings or wood.) This product has infinite possibilities depending on the customer's ingenuity, such as installing acoustic panels at an angle on one wall or ceiling of a room, such as in a concert hall, or if you want the height of acoustic panel A to be 1200 mm or more, and use it as a small speaker at 600 mm. It can also be used in conjunction with Otokobo Z's acoustic pole. Effects that can be expected from this acoustic panel ◯ Improving localization variations ◯ Diffusion of sound (diffuser) ◯ Countermeasures against flutter echoes ◯ Increased sense of low frequency range ◯ Measures against standing waves in the 100-200Hz band ◯ Effect of shortening reverberation time (sound absorption panel) ◯ Makes the sound more beautiful Please take a look at the photos of what happens with laminated wood.There may be places where there are defects in the wood that have been corrected with putty. Extremely large items will be removed during inspection, but please forgive us for minor defects.
