For more powerful bass, the Studio 8IW features an 8" (203mm) Polyplas® cone woofer and a 1" (25mm) Compression Driver with High-Definition Imaging (HDI™) waveguide for more impact from front, side, and rear channels. The Dog Leg mounting system allows for easy installation and the zero bezel grilles make the 8IW visually discrete so they blend into the walls seamlessly. High Frequency Transducer1" (25mm) Compression Driver with High-Definition Imaging (HDI™) waveguideLow Frequency Transducer8" (203mm) Polyplas® wooferNominal Impedance6-OhmSensitivity (2.83V@1m)93dBPower Handling60W RMS (250W Dynamic)Recommended Amplifier Power50 - 80WFrequency Response43Hz - 20kHzCrossover Frequency2.5kHzGrille Dimensions (HxW)9.9" x 13.7" (251mm x 349mm)Cutout Dimensions (HxW)8.7" x 12.5" (221mm x 318mm)Mounting Depth3.74in (95mm)
