JBL Selenium 12" Professional Woofer 300W RMS 8 Ohm – 12PWX-8R

Overview

The JBL Selenium 12PWX-8R is a high-performance 12-inch woofer designed to deliver robust low and mid-low frequencies for professional sound reinforcement and demanding automotive audio systems. Engineered with JBL's rigorous standards, this driver features a magnetic assembly optimized via Finite Element Analysis (FEA) and a stamped steel frame that ensures structural rigidity and durability in mobile applications.

At the heart of the 12PWX is a cone manufactured with Multi Composite Fiber (MCF) technology, exclusive to JBL, which provides the ideal balance of lightness and resistance for distortion-free reproduction even at high power levels. Its new suspension geometry allows for a flatter response curve, making it an excellent choice for 3, 4, or 5-way systems in nightclubs, auditoriums, or high-output "trio" car audio builds where clear, punchy mid-bass is essential.

Features

• MCF Technology – Cone constructed with Multi Composite Fiber for superior strength, reduced weight, and minimal distortion.
• High Power Handling – Capable of handling 300 Watts RMS and up to 600 Watts of continuous musical program power.
• Optimized Cooling – Features a ventilated magnet assembly that dissipates heat efficiently, ensuring consistent performance during long sessions.
• Versatile Application – Ideal for mid-bass reinforcement in PA systems, stage monitors, and high-performance car audio.
• Durable Build – Built on a rigid steel chassis with black epoxy finish and an impregnated fabric suspension for longevity.
