A great value pack for peace of mind! This is the new and improved damping sheet from NUTS LAMP. 【Differences from general-purpose and pre-made products】 〜Custom-made directly from the factory〜 ・Thickened to 2.6-2.9mm to increase damping effectiveness! It's a small difference, but when applied to dozens or hundreds of sheets, the difference becomes clear. ・Wrinkles and unevenness that can occur when rolled are significantly reduced. We wanted to deliver a higher quality product because it's something you can use for a long time once applied. ※There is no expiration date. You can store any leftovers and use them again when needed! 【Size】Approx. 5cm x Approx. 10cm Thickness: Approx. 2.6-2.9mm Number of sheets: 200 Shop Kaze Kobo also offers many other products, such as headlights, fog lights, and sound quality improvement sheets, so please check out the hashtags and my page! #shop風工房の音質向上委員会 (Shop Kaze Kobo's Sound Quality Improvement Committee) 【Product Description】 The surface (blue part) is aluminum. You can use it immediately after peeling off the brown backing paper. It's cut to an easy-to-use size, making it perfect for partial use on door panels, etc. This damping sheet has a high damping effect and can suppress rattling and resonance. Also, the mid-bass range is improved, so you can expect realistic sound. It is also called deadening vibration damping sheet, vibration damping material, etc. 【Impressions】 This is my personal experience using it. First of all, the sound quality has improved significantly. The midrange used to sound cheap, but now it has a deep, high-quality sound. I could hear the guitar and drums clearly. I was surprised that the same speakers could sound so different. You can clearly hear the difference in sound by knocking on the door from the outside before and after application. Before application, it resonates with a "bang," but after application, it sounds like "kon, kon," a sound that doesn't resonate, as if it's packed tightly inside. 【Caution】 ・Due to the characteristics of butyl tape, the thickness may be slightly uneven in some areas. ・Cutting is done by hand, so there may be slight deviations. ・The logo position is random. Recommended for those who use Regulex, Real Schild, and other damping sheets and damping materials. We support those who are challenging deadening with DIY!
