Pioneer Pioneer TS-G690

Each speaker has a mica-reinforced IMPP (injection-molded polypropylene) woofer. This process of cone molding assures a uniform cone thickness to improve linearity and clarity. Additionally, the cones are lightweight and rigid to decrease distortion. The woofers use rubber treated cloth surrounds for improved durability. Each speaker has a 1-7/8" mixed pulp cone midrange. Each speaker uses a 3/8" dome tweeter made from PET (Polyethylene Terephthalate) film for crisp, clear highs.
