Silver Flute W17RC38-04 6.5" Wool Cone Woofer - 4 ohm - Each

The Silver Flute line offers exceptional value, build quality, and versatility. The woofer cones and dust caps are made from a special mixture of wool and paper fibers. These wool fibers help reduce cone resonance, and give the woofers a slightly warmer sound than traditional paper cones. The woofers have durable rubber surrounds and robust cast metal frames. The large voice coils are vented through the back plate. All Silver Flute woofers are available in both 4 and 8 ohm. Consider this product for home stereo, surround sound, autosound systems, and commercial line arrays. Please look at the mechanical specifications carefully as terms like 5" and 6.5" are generalizations.
