AudioControl SPK-8S4

Take control of your low end

With over 45 years of experience, AudioControl knows how to bring great sound to car audio. Their new Spike Series subwoofers are made to deliver deep, full bass that brings your music to life. The SPK-8S4 8″ 4-ohm subwoofer features a mica-coated fiber matrix paper cone that delivers warm, natural sound, while the dual damping system and dual dust caps keep the cone on track. A sturdy stamped steel frame offers solid support.

AudioControl knows you want to turn it up, so they’ve equipped the Spike Series with a heavy-duty 3-layer voice coil former to handle high power. And with 350 watts of RMS power handling, this sub can dish out all the bass you’ll need and is suitable for sealed or ported enclosures. A metal mesh protective grille keeps your speaker safe.
