Series II woofers delivers the enhanced efficiency and higher output. A switch on the input terminal allows you to easily change the woofer's impedance between 2Ω and 4Ω settings.JBL uses progressive spiders to provide the best possible control at the excursion limits versus much more commonly used linear spiders.
