X-Series XV4 15" 3000W RMS Subwoofer
The Sundown Audio XV4 15″ Subwoofer delivers the ultimate low-frequency experience for serious bass lovers. Built with the advanced X v.4 coil design, this subwoofer offers extreme power handling and consistent performance under heavy loads.
With up to 2750W RMS and 5500W peak power, it ensures clean, distortion-free sound even at the highest volumes. The durable motor structure and optimized cone area (72.58 in²) provide deeper lows and better air displacement for maximum sound pressure.
Engineered for flexibility, the XV4 15″ works best in ported enclosures (4.25 cu ft, tuned to 32 Hz) but can also be customized for complex box designs like 4th order setups. Every element — from the high-grade magnet to the precision voice coil — is crafted to deliver unmatched performance and reliability.
Perfect for audiophiles and competitors seeking solid bass impact, this subwoofer combines engineering excellence and raw power in one package.
