Audibax GR15-AR - Professional 15” Woofer (8 Ω, 250 W RMS) for replacement and flush mounting

Audibax GR15-AR - Professional 15” Woofer (8 Ω, 250 W RMS) for replacement and flush mounting

The Audibax GR15-AR is a 15-inch woofer designed for replacements and professional audio projects. It delivers 250W RMS (up to 400W peak power), a nominal impedance of 8 ohms , and a frequency response of 30Hz to 3.5kHz , effectively covering the bass range in passive PA cabinets, floor monitors, and installed systems. It features a vented magnet for improved heat dissipation, a rigid suspension for enhanced cone control, and spade terminals for quick and reliable connection. With a sensitivity of 88dB (1W/1m) , a 1.5” voice coil , and a light weight of 2.3kg , it integrates easily into standard 15” (≈ 381mm) enclosures thanks to its verified dimensions and flush-mount design.

Frequently Asked Questions

Is it compatible with my box?
Check that your enclosure is 15” and 8 Ω and that the mounting dimensions (400 × 400 × 170 mm) and available depth (≥ 140 mm) fit your speaker cabinet.

Do I need a filter/crossover?
In 2-way systems, the use of a passive crossover suitable for the cutoff frequency and the power of the system is recommended.

How do I connect it?
Using spade terminals . Respect the polarity (+/–) indicated on the box/filter.

Is it suitable for domestic use?
It is designed for professional sound applications and installation projects. It can be used for DIY projects if the enclosure design and filter are properly calculated.

What is the difference between RMS and peak power?
The RMS power (250 W) is the reference for continuous use; the maximum power (400 W) is tolerance for short peaks.

Compatibility and assembly

• Format: 15” (≈ 381 mm) with an outer diameter of 385 mm .
• Installation: recessed mounting; check the opening and depth of the enclosure according to the measurements provided.
• Connection: spade terminals; crimping or using quality faston is recommended.
• Impedance: 8 Ω nominal; confirm that it matches the impedance of the enclosure and stage.
