AUDIOFROG GB12D4 GB Series 12″ Dual 4-ohm Subwoofer

Product Description:

The Audiofrog GB12D4 is a 12″ (300mm) flagship audiophile-grade subwoofer, sharing the same elite construction as the D2 version but featuring dual 4-ohm voice coils. This model is the premier choice for multi-subwoofer systems or for users with mono amplifiers that reach their peak efficiency at a 2-ohm load. It is engineered for massive displacement with 19mm of linear one-way excursion, allowing it to reproduce the lowest frequencies with startling realism and physical impact. Like all GB subwoofers, it utilizes a massive 3″ (75mm) voice coil and a low-distortion motor design to ensure every bass note is musical, tight, and free of coloration.

Product Features:

• Dual 4-Ohm Voice Coil Configuration: Offers versatile wiring; most commonly wired in parallel for a 2-ohm load, or in series for an 8-ohm load in high-voltage configurations.
• Massive 3″ Voice Coil: Wound on a high-temperature fiberglass former, providing the thermal stability needed to handle 500W RMS of continuous, heavy-duty playback.
• Extreme 19mm Xmax: One of the highest linear excursion ratings in its class, allowing this 12-inch driver to move a significant volume of air for deep, authoritative sub-bass.
• Low-Distortion Motor: Features a copper inductance-reducing pole piece cap and an aluminum shorting ring to stabilize the magnetic field and reduce non-linear distortion.
• Rigid Vented Basket: The proprietary cast aluminum basket is designed to be acoustically “dead,” preventing resonances and providing a clear path for airflow to cool the voice coil.
• Treated Paper Cone & NBR Surround: Combines a stiff, lightweight treated paper cone with a durable Nitrile Butadiene Rubber surround for a natural tonal balance and long-term mechanical reliability.
