■ Speaker sound quality can be degraded by insufficient door steel plate strength, unwanted resonance, and internal sound reflection and interference. Deadening can address these issues, but this typically requires time-consuming work, including selecting the right materials and modifying the interior of the door. "Sound Engineer" acoustic parts eliminate the causes of sound quality degradation. Simply install them to easily and reliably improve the sound quality of your existing system.
■ The "5 Series" standard package of high-quality inner baffles uses high-rigidity MDF for the inner baffle, which boasts consistent density and hardness. The bottom surface is treated and high-performance vibration-damping paint is used to significantly improve vibration-damping performance. When combined with sound-proofing cushions, it allows for quick and easy sound quality improvement.
■ Utilizes the same vibration-damping paint as the "6 Series" professional package, which maximizes the speaker's inherent capabilities.
■ The inner baffle compensates for the lack of strength inside the door and eliminates unnecessary resonance, resulting in high-quality sound. It is made of high-rigidity MDF, also used in home audio speakers. Unlike natural wood and plywood, which vary in hardness and density, MDF has extremely consistent density and hardness. Even slight differences in the material between the left and right sides of the inner baffle can cause phase shifts, so MDF, with its hardness and excellent vibration-damping properties, is an easy material to improve sound quality. Suppressing door resonance improves low-frequency response, resulting in a sound that exudes a sense of speed.
■ Attaching a cushioning material to the bottom of the inner baffle, where it comes into contact with the door, enhances adhesion to the metal plate inside the door, eliminating distortion and resonance caused by chatter.
■ Includes a sound-proofing cushion to fill the gap between the speaker and the door lining. By using a cushion made of a low-density foam layer with excellent sound insulation properties, it blocks out out-of-phase sound that can get in through the back of the speaker and through service holes, dramatically improving clarity.
■The "High-Quality Inner Baffle Standard Package" includes a highly rigid "MDF inner baffle" that compensates for the lack of strength in the door steel plate and suppresses unnecessary resonance, and a "sound-blocking cushion" that reduces interference from out-of-phase sound that gets in through the back of the speaker. Installation can be done by hand, easily and quickly improving sound quality. *Images are for illustrative purposes only and may differ slightly from the actual product.
