AD-15X350MG – 15” Professional Loudspeaker

Unleash the true power of sound with the Audiotone AD-15X350MG – 15” Professional Loudspeaker driver engineered to deliver outstanding clarity, deep bass, and high performance. With a continuous max power capacity of 700W and an RMS power rating of 350W, this speaker is perfect for professional audio setups, including PA systems, stage monitors, DJ sound systems, and installations demanding consistent and powerful output.

At the heart of the AD-15X350MG is a 75.5mm (3”) CCAW voice coil that ensures excellent thermal conductivity, high efficiency, and reduced weight. This advanced coil construction provides greater control over sound production, enhancing both the accuracy and detail of your audio. With a sensitivity rating of 96 ± 2dB, this driver is built to produce powerful sound with minimal distortion, even at high volumes.

Covering a wide frequency response range from 40Hz to 3000Hz, the AD-15X350MG delivers smooth lows and crisp mids — ideal for full-range or low-mid audio reinforcement. Whether you’re pushing thunderous basslines or detailed vocals, this speaker driver responds with clarity and precision.

Built to last, the AD-15X350MG features a strong metal basket that enhances structural integrity. This rugged frame also helps reduce unwanted resonance, delivering cleaner and more accurate sound. The high-grade Y35 magnet (170×86×20 mm) ensures powerful magnetic flux, resulting in consistent performance even under demanding conditions. Weighing just 5.4 kg, the driver offers the perfect balance between power and portability.

FAQ Section

1. What unique performance role does a 15-inch lower-midrange loudspeaker fill in a professional sound setup?

A 15-inch driver optimized for lower-mid and core midrange frequencies (spanning 45Hz to 3500Hz) is designed to deliver a massive lower-midrange presence and impactful chest-thumping energy. In a standard two-way PA cabinet or stage monitor, its job is to move a substantial volume of air to give instruments and lower vocal registers body and warmth.

2. Why is an inside/outside voice coil winding structure critical for a 350W RMS driver?

An inside/outside wound voice coil features copper wiring wrapped on both the inner and outer surfaces of the cylindrical glass-fiber former. This specific manufacturing layout effectively doubles the physical surface area directly exposed to cooling airflow and the metal pole pieces inside the magnetic gap.

3. What acoustic benefits does a 3-inch (75.5mm) voice coil diameter provide in a 15-inch woofer?

A 3-inch voice coil strikes an ideal engineering sweet spot for a utility lower-midrange transducer. It provides a significantly larger surface area for power handling and thermal stability than smaller 2-inch or 2.5-inch coils, yet avoids the added physical mass of a heavy 4-inch coil.

4. How does the choice of a premium Y35-grade ferrite magnet optimize transient response?

Y35 is a highly saturated grade of sintered ceramic ferrite designed to deliver a dense, uniform magnetic flux field within the voice coil gap. This intense motor force gives the speaker strict mechanical command over the cone’s physical displacement. It forces the cone assembly to start and stop near-instantly with incoming electrical signals.

5. What are the best active crossover parameters to configure on a DSP for a 15-inch lower-mid unit?

To safeguard the suspension from mechanical damage and maximize vocal intelligibility, precise filtering via a Digital Signal Processor (DSP) is recommended. For typical multi-way full-range configurations, program a High-Pass Filter (HPF) set between 45Hz and 60Hz using a sharp 24dB/octave Linkwitz-Riley slope to reject non-reproducible sub-low frequencies that cause mechanical over-excursion.
