Soundstream overheard, and we listened. “Design a subwoofer for SPL!” The Limited Production X5 Series Subwoofer was designed for bass heads by bass heads. These monstrous subwoofers have exceptional specifications; 4” Dual 1Ω Voice Coils, numerous large vents for fast heat dissipation, beefy triple-stacked magnet assembly, and 8ga Duplex direct wire hookups.

X5.12 and X5.15 were crafted to help Team Soundstream move in the direction past standard production subwoofers. These pair nicely with the newest Soundstream amplifier arsenal, the “Tarantula XP” High Output series. Both subwoofers can handle up to 3,500w RMS… which is sure to set off some alarms!

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. ½ Ohm is wild…
