Sundown Audio E-15 V.3 500W RMS Dual 4-Ohm Subwoofer

RMS Power

• 500-watts: The RMS power rating ensures reliable performance even under demanding conditions. Ideal for environments where higher sound levels are necessary.

Xmax and BL

• Xmax = 14mm one-way by 70% BL: High Xmax and efficient BL design provide strong, consistent performance. This ensures that the loudspeaker can handle powerful signals without distortion.

Vented Magnetic Gap and Pole Piece

• vented magnetic gap with optimized geometry: Optimized magnetic gap design enhances efficiency and reduces magnetic back EMF, leading to improved sound quality and reduced distortion.
• vented pole piece: A vented pole piece increases air flow, contributing to better cooling and overall reliability.

Voice Coil

• Black Aluminum 2.5” voice coil former: The voice coil former is made of black aluminum, providing superior heat dissipation. This helps in maintaining consistent performance and prolonging the life of the loudspeaker.

• High Temperature 4-Layer copper voice coil wire: The use of high-temperature copper wire ensures durability and reliability in high-heat conditions, enhancing overall lifespan and performance.

Electrical Connections

• Spring Loaded Terminals: These terminals provide secure and easily adjustable connections, ensuring optimal performance and reducing the risk of connection failure.
• Stitched-On “Mini-XL” Tinsel Leads: These leads are designed to prevent fatigue and failure, providing long-term reliability and stability.

Enclosure Recommendations

• Sealed Box Recommendation: 2.5 ft³: Suitable for environments where a tight, controlled sound is desired.
• Ported Box Recommendation: 3.25 ft³: Ideal for broader, more dynamic sound distribution.
• Displacement: 0.14 ft³: This displacement size is optimal for ensuring the loudspeaker operates efficiently in the recommended enclosures.
• Depth: 7 1/4" and Outside Diameter: 15 1/8": These dimensions make the loudspeaker easy to install and integrate into various setups.
• Cut-Out: 13 7/8": This cut-out size ensures proper installation and optimal sound performance.
• Recommended Tuning: 32Hz and Recommended Port Area: 52 in²: These specifications provide the best setup for achieving the intended sound quality and performance.

These key features ensure that this loudspeaker not only delivers exceptional sound quality but also provides long-term reliability and performance.
