      Descrizione del prodotto GRS 18PT-8 Woofer

      The GRS 18PT-8 18” professional paper cone woofer will deliver high output bass response without breaking the bank. Packed with features like a 3” voice coil, inductance reducing copper cap, under spider venting, and gap vents; this driver is built for high performance, low distortion, and incredible reliability. Whether you need a drop-in replacement for a worn-out professional subwoofer or are working on a completely new design, the 18PT-8 is the perfect driver for budget builds.

       

      Highlights

      • Lightweight ribbed paper cone allows high efficiency with minimal resonance
      • 3” diameter voice coil on heat resistant Kapton former handles up to 350 watts RMS
      • Great displacement capability is ideal for high output subwoofer designs
      • Extensive venting keeps cool air flowing across the voice coil to minimize power compression
      • Inductance lowering copper cap reduces distortion and extends high frequency response
      • Spring-loaded push-button terminals makes wire connections quick and easy
      • Foam front gasket ensures an airtight seal for rear mount installations

       

      Product details

      GRS 18PT-8 18" Paper Cone Professional Woofer with 3" Voice Coil 8 Ohm

       

      Engineered for high output with powerful low frequency extension, the 18PT-8 18” professional woofer is ideal for use in large low-cost sound systems. Packed with features you would expect from much more expensive drivers, the 18PT-8 is built for low distortion and reliability even when pushed to its limit. The lightweight reinforced paper cone has excellent damping properties, minimizing unwanted resonances, and the ribbed surface controls cone breakup to ensure smooth response all the way up to 1,000 Hz. Driving the cone is a 3” diameter dual-layer voice coil that is wound on a heat resistant polyimide former to handle up to 350 watt RMS. Extensive venting through frame, pole piece, and magnetic gap cools the voice coil to prevent thermal runaway and lower power compression during long sessions at high power. With a copper cap on the pole piece keeping inductance under control, you can ensure that the 18PT-8 will provide low distortion throughout its useable bandwidth. Whether you need a drop-in replacement for a blown professional subwoofer, or are designing a new system, the 18PT-8 is the ideal choice if you want high impact low frequency response without spending a fortune.
