Designed and engineered at JBL’s world-famous Acoustic Engineering Center of Excellence in Northridge California the Stage 280F is the flagship of the JBL Stage Series. This floorstanding loudspeaker features a 2.5-way design with Next Generation patented High-Definition Imaging (HDI™) waveguide geometry 1” Anodized Aluminum dome tweeter and dual 8” Polycellulose ribbed cone woofers that provide deep signature JBL bass.FeaturesDual 8” Woofers & 1” Tweeter2.5-Way DesignDedicated ATMOS 5-Way Binding PostsWide Soundstage & Signature JBL BassCompatible with the 240H Atmos ModuleDual 8” Polycellulose Ribbed Cone WoofersThe 280F features Polycellulose ribbed cone woofers. This pure pulp cone has a proprietary mix of other materials added to improve its rigidity and the ribs echo legendary JBL designs. These woofers produce deep accurate room filling bass.1” Anodized Aluminum Tweeter Through intense research of previous waveguide designs JBL has developed a new complex geometry that improves directivity reduced diffraction and an overall neutral frequency response both on and off axis. The Stage 2 HDI Horn is coupled to an anodized aluminum dome tweeter to enhance efficiency and dynamics.Precision 2.5-Way CrossoverThe 280F floorstanding model features a unique two and a half-way crossover design. This unique design crosses over the top woofer right below the tweeter's output while the other woofer is crossed over at a lower frequency. This creates a dynamic mid-range but both woofers still extend as deep as they can go for powerful bass. This produces cohesive balanced output with a robust low end that can be both heard and felt. Premium components are used to construct the crossovers fitted to the Stage 2 line. The High frequency section features air core inductors and mylar capacitors that reduc | Jbl | | Stage 280F Dual 8" Floorstanding Speaker | White | Best Buy
