• 9" Aluminum Cone Woofer:The E-9 F uses a stiff, lightweight aluminum cone woofer designed for speed and control, moving a significant amount of air to deliver powerful and precise bass. The aluminum's rigidity, with a Young's modulus of 69 GPa, also ensures piston-like movement, minimizing distortion.
• Powerful Class D Amplifier: A 170W RMS (220 Peak Watts) Class D amplifier provides high continuous power with absolute linearity, ensuring the audio signal's integrity and allowing the subwoofer to handle demanding audio tracks. 
• Down-firing Bass Port:The woofer is paired with an oversized, downward-firing bass port, which adds "virtual cone surface" to the lowest frequencies. This design enhances bass output while reducing stress on the woofer and minimizing total distortion.
• Integrated Controls:The E-9 F includes integrated controls for volume, phase adjustment, and crossover frequency, making it easy to adjust to your system and room. 
• Stylish & Compact Design:The subwoofer features a stylish cabinet design that blends effortlessly into any room. It is elevated from the floor by four oversized, cone-shaped rubber feet or polymer spikes, which also help to eliminate turbulence under the cabinet.
• Excellent Integration:The combination of a fast-responding aluminum cone and powerful amplification allows the E-9 F to integrate seamlessly with your main speakers, providing a well-balanced and dynamic low-frequency extension.
