The SB Acoustics SB15NRX2C30-4 is a 5-inch bass-midwoofer speaker driver that is 8designed to produce high-quality sound. The vented cast aluminum chassis provides the speaker with optimum strength and low compression, which helps to reduce distortion and improve sound quality. The proprietary cone material with natural fibers made in-house is designed to provide a high level of rigidity and low mass, which helps to improve the speaker’s transient response and overall sound quality. The soft low damping rubber surround is designed to provide a high level of damping, which helps to reduce distortion and improve the speaker’s transient response. Finally, the non-conducting fiber glass voice coil former is designed to provide a high level of damping, which helps to reduce distortion and improve the speaker’s transient response.
