185-2/AdPower Sonic
>> Product Overview AdPower Sonic is a sound-tuning sheet that applies the patented static electricity suppression technology developed through the automotive AdPower series to a d edicated audio sheet. Developed under the supervision of Koji Morimoto, Chief Recording Engineer at Avex, improvements in sound quality can be expected simply by applying it to audio equipment. It has received high praise from many composers, professional musicians, and recording engineers, and is used and loved by audio enthusiasts around the world, including in Japan. The Speaker & Audio Equipment Series can be applied to a wide variety of audio systems, including speakers, musical instruments, and audio equipment. Its effectiveness has been scientifically verified through research collaboration with the National Institute of Advanced Industrial Science and Technology (AIST) and Ritsumeikan University in Japan. >> Key Benefits - Clearer sound definition and imaging — effects such as vocals coming forward, harshness in the high frequencies disappearing, and improved bass clarity can be expected - Just peel and apply — no tools or professional installation needed, easy DIY for anyone - Compatible with all audio equipment — large speakers, Bluetooth speakers, smart speakers, soundbars, musical instruments, and more - Maintenance-free - Affordable sound quality upgrade >> How It Works Sound source analysis conducted at Japan's National Institute of Advanced Industrial Science and Technology (AIST) found that applying AdPower Sonic to speakers tends to increase IACC (Inter-Aural Cross-Correlation Coefficient), an indicator of sound diffusion and spatial spread. Additionally, analysis conducted at Ritsumeikan University showed that in the low-frequency range (250–500 Hz), reverberation tends to lengthen, while at the lowest frequency of 125 Hz, it tends to shorten. These findings suggest that the results may lead to the perception of "tighter bass" and "clearer sound imaging and definition" during actual listening. >> Who Is This For? This product is a tuning accessory designed to pursue subtle changes in sound quality, such as sound definition and imaging. If you have any of the following concerns, AdPower Sonic is recommended for you. - Not fully satisfied with the sound quality of your current speakers or audio equipment - Want to improve your sound without replacing your audio equipment - Feel that your sound lacks depth or spatial presence Please note: If you are looking for a dramatic change in sound, please be aware that this product may not meet your expectations. >> Specifications - XS Size (Hexagonal): 1.4 cm diameter × 0.1 cm thick | 0.2 g - S Size (Rectangular): H 1.6 cm × W 3.2 cm × 0.1 cm thick | 0.8 g - M Size (Rectangular): H 2.7 cm × W 7.5 cm × 0.1 cm thick | 3 g >> Recommended Size Please select the AdPower Sonic size based on your woofer unit size. - Up to 4 inches (100 mm): XS size - Up to 6 inches (150 mm): S size - Up to 10 inches (250 mm): M size If you have any questions about size selection, quantity, or installation, please feel free to contact us. >> How to Install Before purchasing: Please check your speaker's woofer size and other equipment details, and confirm the number of sheets and sizes you need. 1. Without any sheets applied, play a familiar track for about 30 seconds. Turning up the volume makes it easier to notice changes. 2. Apply all AdPower Sonic sheets to the appropriate positions. 3. Play the same part of the track again and enjoy the changes after installation. >> FAQ Q1. What if I don't notice any effect? A1. Sound perception varies by individual and also differs depending on environment and equipment. However, as the sheet continues to suppress static electricity, we recommend leaving it on. Also, if the size, quantity, or placement is not appropriate, the effect may be harder to notice. Please double-check that the installation is correct. If you have any questions, please feel free to contact us. Q2. What if I want more effect — or feel it's too strong? A2. If you want more effect, it can be adjusted by purchasing additional sheets. If you feel the effect is too strong, it can be adjusted by reducing the number of sheets or downsizing. Q3. Where should I apply the sheets? A3. For speakers with a bass reflex port, the bass reflex port is the primary recommended position. If there is no bass reflex port, please apply the sheet to the baffle — the surface on which the speaker unit is mounted. For other speakers, audio equipment, or musical instruments, please contact us and we will be happy to assist you. Q4. Is there an expiration date? A4. AdPower Sonic does not have a set expiration date. However, as the product does deteriorate over time, we recommend replacing it every 2–3 years depending on your usage environment. Q5. Can I reapply the sheet? A5. Reapplication is possible, however it may reduce adhesion and could cause the sheet to fall off. Please avoid reapplying the sheet more than necessary. >> Customer Reviews "The sound definition became clearer. There was less variation depending on where I listened, and the room's acoustic influence was reduced. Good sound now reaches the seats at the back of the studio. Imaging also improved." (Recording Engineer A / Speaker used: Westlake Audio BBSM-4) "The bass became tighter and the vocal range became clearer." (Recording Engineer C / Speaker used: PreSonus Sceptre S6) "The speed of low and high frequencies became more consistent. There was less change when I moved my listening position. I was able to achieve an imaging that felt like listening through headphones." (Mastering Engineer / Equipment used: Monitor speakers, amplifier, preamplifier) "Unwanted noise disappeared, the sense of power increased, and playing became more comfortable. Unnecessary resonance also decreased and the sound became clearer." (Drummer / Equipment used: Drums) * Sound perception may vary depending on environment, equipment, and individual sensitivity.
