      Product details

      SB Acoustics SB12NRXF25-8 Norex Bass-midwoofer 8 ohm

       

      The SB12NRXF25-8 is a well-rounded 4-inch, 8 ohm, full-range driver that is capable of delivering clear, accurate sound in a variety of applications. It is a good choice for bookshelf speakers, satellite speakers, and subwoofers. The proprietary cone material is made from a blend of natural fibers that is said to provide a more natural and balanced sound than traditional paper cones.

       

      The foam surround is designed to provide a smooth and accurate response in the midrange frequencies. The vented cast aluminum chassis helps to dissipate heat and reduce distortion. The CCAW voice coil is lightweight and provides good power handling. The long life silver lead wires are resistant to corrosion and oxidation. The non-conducting fiberglass coil former helps to reduce noise and distortion. The shorting ring in the motor system helps to reduce distortion at high frequencies.
