A Hokuriku-born car accessories brand inspired by the midsummer sea, "NUTS LAMP".

You can use them on doors, interior panels, and around speakers. It can also be combined with deadening sheets, and further improvement in sound quality can be expected! Born from the voices of many customers! It took half a year to commercialize, and we were particular about the quality and shape! We compared the sound of more than 10 types of materials with 3 people, and carefully selected the thickness and material from scratch. We created it with the intention of satisfying even the experts! 【Contents】 Castella (speaker surround sound-absorbing material) 10 pieces Size: Approximately 25mm x 25mm x 590mm per piece 【Features】 ■Castella The shape and material are designed to maximize the effect even in the narrow environment of speakers and interior panels! The low-rebound, moist material, like Castella cake, won't damage the speakers. Please touch it once and feel its gentle texture! Both Castella sets adopt a wave shape! This wave shape is also widely used in concert halls and music studios. By making the surface area wider than a flat shape, more reflected sound can be absorbed, and further improvement in sound quality can be expected. 【Great value with a set!】 Normally 398 yen per piece, 3980 yen for 10 pieces, → Special discount price: 2600 yen for 10 pieces!!
