Audio Ace Jester Series 18" Subwoofer Dual 2 Ohm

18-inch Audio Ace Jester Series Dual 2 Ω subwoofer rated at 3,000 RMS, built for high-SQ/SPL and versatile bass performance across music styles.

• RMS power handling: 3,000 W RMS rating provides the capability to reproduce deep bass with authority when paired with a suitable amplifier and ventilation.
• Impedance: Dual 2 Ω voice coil configuration offers wiring flexibility to match amplifiers and impedance needs in a complex build.
• Voice coil: 3-inch four-layer voice coil enhances power handling and heat dissipation for sustained high-output performance.
• Magnet: 300 oz magnet structure delivers strong motor force for controlled excursion and low-frequency extension.
• Basket: Heavy duty die cast aluminum basket adds rigidity and helps manage heat under demanding duty cycles.
• Suspension: 4-layer spider suspension supports linear motion at high excursion for consistent bass response.
• Mounting depth: 16.85 inches mounting depth defines enclosure space requirements and installation considerations.
• Electrical parameters: Re 3.53 Ω; Le 3.462 mH; Qts 0.550; Qes 0.605; Qms 6.006 provide a picture of the voice coil, coil inductance, and overall motion control characteristics.
• Enclosure recommendations: Ported enclosure 4.75–5.5 cu ft; 14–16 in² of port per cu ft; tuning 28–36 Hz; optimal for ported 4th and 6th order; not recommended for sealed.

In a proper ported installation, the Jester 18" delivers extended, controlled bass with the ability to fill large spaces when paired with the right amplifier and enclosure. The 16.85" mounting depth and port tuning guidance align with builds that prioritize deep low-end extension and specific ported alignments, while the not-for-sealed guidance helps ensure the design is used in environments where it can perform as intended.
