Since its founding in 2008 in Guangzhou, China, Huiyin Audio has stood as a beacon of excellence in the audio industry, specializing in professional and car audio systems that blend innovation with reliability. Recognized as a high-tech enterprise in 2017, we leverage state-of-the-art automated production lines and precision testing equipment to craft products that meet the most rigorous standards. Today, we’re thrilled to showcase the HYW-1575-039B-4—our 15-inch low-frequency (LF) driver that embodies our commitment to power, durability, and acoustic precision. Designed for audio professionals, enthusiasts, and commercial users alike, this speaker delivers uncompromising performance in every application. Let’s explore the engineering, specifications, and versatility that make the HYW-1575-039B-4 a game-changer in its class.
The HYW-1575-039B-4 is built around a suite of carefully calibrated specifications, each working in harmony to deliver consistent, high-impact sound. Every parameter is rooted in real-world functionality, ensuring the speaker excels in demanding environments where power and clarity are non-negotiable.
At its core, the speaker features a 15-inch nominal diameter, paired with a 4Ω nominal impedance (RE = 4Ω)—a design that ensures seamless compatibility with a wide range of amplifiers, from professional rack systems to car audio setups. What truly sets it apart is its exceptional power capacity: an AES power handling rating of 3000W and a continuous program power of 6000W. This robust power reserve means the HYW-1575-039B-4 can endure hours of high-volume operation without distortion, making it ideal for large venues, live performances, or high-performance car audio systems. Whether you’re powering a stadium sound system or upgrading your vehicle’s bass response, this driver’s power handling ensures it never misses a beat.
Versatility in frequency reproduction is key to a top-tier LF driver, and the HYW-1575-039B-4 delivers with a frequency range of 36Hz to 500Hz. This range is optimized for deep, resonant bass—perfect for genres like hip-hop, EDM, and rock—while maintaining clarity in the lower midrange, ensuring speech and musical details come through crisply. Complementing this range is a sensitivity of 90dB (1w/1m), which translates to efficient power-to-sound conversion. Even with moderate amplifier input, the speaker produces loud, clear output, making it energy-efficient without sacrificing performance. For commercial venues like nightclubs or concert halls, this combination ensures the audience feels every low-frequency note with precision and depth.
Beneath the surface, the HYW-1575-039B-4 boasts impressive electrical and mechanical characteristics that elevate its performance. The BL factor (magnetic force) of 23.3337 delivers strong cone control, ensuring tight, accurate bass reproduction even at high volumes. The total quality factor (QTS) of 0.4170 strikes a perfect balance between low-frequency extension and damping, making the driver adaptable to various enclosure designs—from sealed cabinets to ported systems.
On the mechanical front, the effective moving mass (MMS) of 268.1954 and resonance frequency (FS) of 35.9662Hz work in tandem to reproduce deep bass without unwanted resonance. The effective piston area (SD) of 0.0855m² maximizes air displacement, enhancing low-frequency output, while the compliance (CMS) of 0.0730 and equivalent case air load (VAS) of 74.5822 L ensure consistent performance across different installation setups. The electrical quality factor (QMS = 6.5808) and mechanical quality factor (QES = 0.4453) further refine the driver’s response, minimizing distortion and optimizing efficiency. These aren’t just numbers—they’re the result of meticulous engineering that ensures reliability in real-world use.
Huiyin Audio’s dedication to quality shines through in every component of the HYW-1575-039B-4. Each part is selected for its durability, acoustic performance, and long-term reliability, reflecting our promise to build products that stand the test of time.
The voice coil is the heart of any speaker, and the HYW-1575-039B-4 features a 75mm diameter coil wound with four layers of round aluminum wire. Round aluminum wire offers excellent conductivity and heat dissipation, allowing the coil to handle high power levels without overheating—critical for prolonged use in professional settings. The coil is mounted on an aluminum former, which enhances structural rigidity and further improves heat management, preventing performance degradation during intense use.
Complementing the voice coil is a robust magnetic assembly: three ferrite magnets that deliver consistent magnetic flux density for precise cone movement. Ferrite magnets are chosen for their stability, cost-effectiveness, and ability to maintain performance in varying temperatures—ideal for both indoor and outdoor applications. The magnetic gap depth of 12mm ensures optimal interaction between the voice coil and magnet, minimizing distortion and maximizing power transfer. With a winding depth of 60mm, the voice coil maximizes contact with the magnetic field, further enhancing control and power handling.
The speaker’s surround is crafted from paper cone high-foam material, designed in a U-shape for maximum flexibility and durability. The U-shape allows the cone to move freely, even at extreme displacements, while the high-foam material absorbs vibrations that could cause distortion. This design ensures the driver maintains clarity and consistency, whether it’s reproducing deep bass notes or handling transient peaks in music.
Every structural component is engineered for rigidity and longevity. The speaker’s frame is built to withstand the rigors of professional use—from touring stages to mobile audio setups—while the precision assembly ensures consistent performance across every unit. Huiyin Audio’s automated production lines eliminate human error, guaranteeing that each HYW-1575-039B-4 meets the same high standards of quality and performance.
The HYW-1575-039B-4 is designed with versatility in mind, featuring mounting and physical specs that make it suitable for a wide range of applications—from professional sound systems to custom car audio builds.
The speaker’s overall diameter of 389mm and panel cutout diameter of 356mm ensure compatibility with standard speaker enclosures and mounting bracings. The bolt circle diameter of 375mm (with 8 holes of Ф6.5mm) provides a secure, stable installation, whether you’re mounting it in a speaker cabinet, stage rig, or car door. At just 220mm in depth, the driver is compact enough for most installation spaces while still accommodating its robust magnetic assembly and voice coil—making it a flexible choice for tight setups.
With a net weight of 14KG and a shipping weight of 15KG, the HYW-1575-039B-4 is sturdy yet manageable for transportation and installation. The single packaging dimensions (425×425×268mm) are engineered to protect the speaker during transit, with durable packaging materials that shield against impacts and vibrations. Whether you’re shipping the driver to a venue or transporting it between gigs, you can trust it will arrive in perfect working condition.
The HYW-1575-039B-4’s blend of power, frequency response, and durability makes it suitable for a diverse range of applications, aligning with Huiyin Audio’s focus on both professional and car audio solutions.
