Our take on the JBL Decade Series 5"x7"/6"x8" Speakers


It's a whole new Decade — both on the calendar and in your vehicle — once you install JBL's famous Decade series DS755 5"x7"/6"x8" speakers. The treated pulp cone holds its shape while playing tight bass. The titanium-composite tweeter ensures smooth, clean highs, regardless of your output level. A polyurethane surround offers years of dependable service.
