      Product description

      The GRS SPBF-8 is a high sensitivity 8 ohm, 60W 5.25” sealed midrange with a 1” diameter voice coil and polyimide former. This midrange driver uses a durable poly cone body and foam surround. It is a dedicated midrange for 2-way and 3-way projects. The sealed frame means it does not require a separate enclosure. Use it as a replacement speaker or add to an existing system.

      • High sensitivity for maximum output
      • Extended frequency range out to 9kHz

      Product Details

      SPBF-8 5-1/4" Sealed Back Midrange with 1" Voice Coil 8 Ohm

       

      The GRS SPBF-8 is a 5-1/4" sealed midrange driver with low distortion characteristics and predictable performance, making this a great component for speaker designers. The sealed back frame provides isolation of the cone when installed in cabinets with larger woofers so the SPBF-8 performs consistently, regardless of what enclosure you use!

       

      The GRS SPBF-8 sealed midbass driver is a great choice for use in dynamic 2-way and 3-way designs. Thanks to the sealed frame providing the perfect compliance volume for this driver, the output is consistent for car audio, home hi-fi, and even musical instrument applications!
