Audibax GR12-DE - Professional 12" Woofer (4 Ω, 180 W RMS, vented magnet)

Audibax GR12-DE - Professional 12" Woofer (4 Ω, 180 W RMS, vented magnet)

The Audibax GR12-DE is a 12-inch woofer designed for replacement and construction of speaker enclosures in PA systems, installations, and rental applications. It features a vented magnet for improved heat dissipation, a rigid suspension for enhanced motion control, and a 1.5" voice coil , delivering a sensitivity of 93 dB (1 W/1 m) and a frequency response of 30 Hz to 3.5 kHz . Its 4 Ω impedance and 180 W RMS continuous power handling (up to 360 W max. ) make it a solid choice for two-way speakers and bass-reflex enclosures where punch and reliability are paramount. Spade terminals facilitate quick and secure wiring during service or workshop installation.

Main features

• Nominal diameter: 12" (30 cm).
• Ventilated magnet: improves cooling and stability during prolonged use.
• Rigid suspension: displacement control for more defined bass.
• Voice coil: 1.5" for thermal management according to 180 W RMS.
• Impedance: 4 Ω, compatible with standard passive amplifiers and filters.
• Sensitivity: 93 dB @ 1 W / 1 m.
• Frequency response: 30 Hz – 3.5 kHz (typical range for use as a woofer).
• Connection: spade-type terminals for quick assembly.
• Lightweight construction: weighs approximately 2 kg for easy transport and assembly.
• Overall dimensions: 300 × 300 × 125 mm.
• Mounting dimensions: 320 × 320 × 140 mm.
• Finish: black color.

Product benefits

• Balanced performance: 180 W RMS with good sensitivity to achieve adequate sound pressure levels without requiring excessive amplification.
• Reliability in continuous use: the ventilated magnet helps keep the temperature under control, reducing heat compression.
• Easy maintenance and replacement: sword terminals and chassis accessible for quick replacements on tours or installations.
• Versatility: suitable as a woofer in 2-way systems for sound reinforcement in halls, pubs, rehearsal rooms, schools and mobile events.

Use cases

• PA speaker repair: replacing the bass driver in 12" cabinets
• DIY construction or retrofit: upgrade of 12" bass-reflex enclosures with 4 Ω impedance.
• Fixed installation and rental: speakers for multipurpose rooms, cultural centers, gyms or rental backline.

Frequently Asked Questions

• What is the actual power? The continuous power is 180 W RMS and the maximum recommended power is 360 W.
• Is it a passive speaker? Yes, it requires external amplification and, in 2-way systems, a suitable crossover .
• Does it work at 4 Ω? Correct, its nominal impedance is 4 Ω .
• What connectors does it use? Spade-type terminals for crimping or snapping into Faston female connectors.

Compatibility and assembly

Before installation, verify the mounting dimensions and the enclosure volume/port to ensure optimal performance. Use appropriately sized wiring and adjust the passive filter or DSP processing to the system's cutoff points to protect the transducer.
