ONKYO Speaker System Units 1 (2 Set) D-412EX

---------------------------------------------------------------------- 【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. ----------------------------------------------------------------------

Equipped with newly developed "A-Silk OMF" diaphragm Accurate ultra-high frequency reproduction, cutting-edge ring tweeter Bass reflex technology that enables high-quality bass enhancement Shut out mutual interference between units Gold-plated brass machined terminal to prevent sound quality deterioration The diaphragm uses a proprietary material that combines strength and flexibility. The woofer uses a diaphragm called A-Silk OMF, a new material made from a hybrid molding of silk, which takes advantage of the natural characteristics of natural materials, and aramid fiber, which is strong and flexible and has a reputation for being used in many fields other than speaker diaphragms. A ring-shaped diaphragm is used instead of the typical dome-shaped diaphragm, and a balanced drive structure is adopted in which the voice coil is placed midway between the outer and inner ends of the diaphragm. Unlike conventional tweeters, it does not rely on divided vibrations, but instead covers frequencies up to nearly 20kHz using only the amplitude faithful to the original signal, achieving ultra-wideband reproduction up to 100kHz. Many compact cabinet-sized speakers are equipped with ducts that emit air vibrations generated inside the cabinet to the outside in order to reproduce deep bass sounds (bass reflex structure). To prevent signals from interfering with each other between the woofer/tweeter units, an isolated mounting method is used to separate each network circuit. The speaker terminal part uses a gold-plated machined brass type with excellent conductivity. High-quality specifications that prevent signal transmission loss at contacts and suppress deterioration of signal conductivity due to aging. *One set of two.
