Power Dynamics PD15PS - 15-inch 800W Woofer with Aluminum Chassis

Power Dynamics PD15PS - 15-inch 800W Woofer with Aluminum Chassis

The Power Dynamics PD15PS is a 15-inch woofer designed to deliver robust, professional-grade, high-fidelity audio performance. This component is the perfect choice for replacing a damaged woofer in an existing system or for starting a new DIY speaker construction project. Its meticulous construction, using premium materials, ensures powerful, clear, and accurate low-frequency reproduction, even in the most demanding environments.

With a peak power of 800W and a continuous (RMS) power of 400W, the PD15PS is ready to handle high sound pressure levels without sacrificing sound quality. Its die-cast aluminum chassis not only provides an extremely rigid structure that minimizes unwanted vibrations and resonances, but also acts as an efficient heat sink, protecting the voice coil during extended use.

Main features

• Cast Aluminum Chassis: Unlike stamped steel chassis, cast aluminum provides a solid and stable base for all components, improving transient response and overall speaker durability. It also helps dissipate the heat generated by the voice coil.
• Fiberglass Cone: The cone is made of fiberglass, a material known for its excellent stiffness-to-weight ratio. This allows the cone to move with precision and speed, resulting in defined, controlled, and distortion-free bass, even at high volumes.
• 3-Inch Voice Coil: Equipped with a high-temperature resistant 3-inch (76 mm) voice coil, the PD15PS is designed to withstand long working days at full power, ensuring consistent reliability and performance.
• High Sensitivity: With a sensitivity of 97 dB (SPL @ 1W/1m), this woofer converts amplifier power into sound very efficiently. This means less power is needed to achieve high volume, optimizing the performance of the entire audio system.
• Simple Spider Suspension: The suspension (spider) design ensures linear and precise control over the cone's movement, improving low-frequency clarity and the overall speaker response.

Benefits for the Sound Professional

The Power Dynamics PD15PS is designed for sound engineers, installers, and musicians seeking reliability and quality. Its robust construction ensures a long lifespan under the demands of professional use on tours or in fixed installations. The combination of the aluminum chassis and fiberglass cone results in superior audio quality, with deep, articulate bass that enriches any mix. Its versatility makes it an ideal solution for a wide range of sound reinforcement applications.

Use cases

This woofer is extremely versatile and perfectly suited to a wide variety of professional audio applications, including:

• PA systems for concerts and live events.
• Main speakers and subwoofers for nightclubs, pubs and party venues.
• High-power stage monitors for musicians.
• Custom speaker construction projects for audio enthusiasts and professionals.
• Replacement and improvement of woofers in 15-inch speaker boxes from recognized brands.

Frequently Asked Questions

What is the actual RMS power of this woofer?
The continuous or RMS power is 400W, while the maximum or peak power is 800W. It is recommended to use an amplifier that delivers around 400W into 8 Ohms for optimal and safe performance.

Is this speaker suitable for a subwoofer or a 2-way system?
Thanks to its wide frequency response (35 Hz - 4,000 Hz), the PD15PS is very versatile. It works excellently as a bass component in a 2- or 3-way system, but it also provides a solid foundation for building a powerful passive subwoofer.

Does the aluminum chassis offer any real advantage over steel ones?
Yes. The cast aluminum chassis is much more rigid and non-magnetic, which reduces distortion and resonances. Furthermore, it dissipates heat from the voice coil more effectively than steel, increasing long-term reliability and power handling capacity.

Project description
