Massive Audio H124X - 12" 2000 Watts RMS Dual 4 Ohm 3" V.C. Mega Subwoofer

The Massive Audio H124X delivers 2000 watts RMS through a 3-inch dual 4-ohm voice coil in a 12-inch package designed for high-output car audio builds that demand both power and accurate bass response.

• Voice Coil: 3-inch dual 4-ohm coil on an anodized aluminum former with triple heavy-duty tinsel leads handles sustained 2000 watts RMS while managing heat and mechanical stress.
• Motor Structure: 274 oz strontium double-stack motor provides the magnetic force needed to control the large voice coil at high excursion levels.
• Cone and Suspension: Non-pressed paper cone reinforced with Kevlar fiber, paired with a tall narrow foam surround and mirrored dual Nomex spiders, maintains rigidity while allowing 20.5 mm X-Max.
• Basket and Cooling: Cast aluminum basket with vented back plate and basket dissipates heat during extended high-power use.
• Terminals: Heavy-duty direct-input wire connections provide low-resistance power delivery without traditional terminal blocks.
• Fs and Sensitivity: 38 Hz free-air resonance and 89 dB SPL rating support efficient output in both sealed and ported enclosures.

This subwoofer suits competition or high-output daily-driver systems where a single 12-inch driver must deliver controlled low-frequency output across varied music without sacrificing durability under prolonged high power. The combination of large voice coil, oversized motor, and rigid cone addresses the common issues of voice-coil overheating and cone flex encountered in demanding installs.
