2-Way 5.25-inch (130mm) Bookshelf Loudspeaker
Designed and engineered at our world-famous Acoustic Engineering Center of Excellence in Northridge, California, the Stage 250B is largest bookshelf loudspeaker of the JBL Stage Series. It provides impressive performance from a small footprint. The 250B's are versatile enough to be used as main speakers or surrounds. This loudspeaker features a 2-way design with Next Generation patented High-Definition Imaging (HDI™) waveguide geometry, 1-inch (25mm) Anodized Aluminum dome tweeter, and a 5.25-inch (130mm) Polycellulose ribbed cone woofer that provides deep, signature JBL bass.
Each speaker in the Stage 2 series 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.
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.
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 reduce distortion and improve sonic performance. The low frequency section includes laminate core inductors and electrolytic capacitors. These premium materials can handle more power and transmit energy faster elevating system performance.
