Detailed Features and Benefits

Robust Die Cast Aluminium Chassis

The cast aluminium enclosure significantly enhances structural stability without excessive weight. This rigid design dampens unwanted resonance, allowing cleaner sound reproduction even under extended heavy-duty operation. Compared to other materials, aluminium better withstands wear in professional environments, prolonging the lifespan of your PA system’s components.

18 inch Woofer Speaker Driver

Featuring an impressive 18-inch diameter, this driver efficiently moves higher air volumes, generating deeper bass responses and greater sonic presence. Its size makes it especially suitable for professional sound setups that need clarity at both low and mid frequencies, ensuring reliable performance during live music events, concerts, and large gatherings.

Heat Resistant 3" Voice Coil

Equipped with a sturdy and well-ventilated 3-inch voice coil, the driver efficiently dissipates heat accumulated from prolonged operation. This prevents the coil from overheating and distortion at high volume levels, allowing continuous performance without damaging the speaker or sacrificing audio quality.

Single Spider Suspension System

The single spider suspension ensures precise control over the driver's cone movement, maintaining accurate linear motion. The result is an improved audio reproduction across the speaker’s operational frequency range. The suspension design also minimises dynamicdistortion, enhancing clarity and transparency in critical listening and sound reinforcement tasks.

Fibreglass Cone Construction

The tough fibreglass cone employed in this woofer provides exceptional stiffness and consistency without adding unnecessary weight. This improves driver sensitivity (98dB SPL @ 1W/1m) and frequency response (35 – 3.500 Hz), creating a smooth, well-defined audio performance. Fibreglass cones outperform traditional paper or plastic cones in terms of long-term reliability under regular use.

Suitable Applications and User Types

The Power Dynamics PD18PS Woofer is perfectly tailored for professional audio technicians, musicians, and sound reinforcement specialists requiring dependable audio output. Utilise as a replacement driver when updating or maintaining PA speaker equipment frequently used in live music venues, festivals, club installations and event spaces. Additionally, installers working on custom audio set-ups benefit from the versatile performance offered by this durable and clearly defined-sounding speaker component.

Given its reliability, it's recommended in commercial sound installations for bars, theatres, churches, performance halls and evening entertainment businesses looking for consistent audio delivery. DJs, bands, audio hire companies, and event organisers can achieve clearer and more responsive sound, optimising audience satisfaction and system longevity.
