Power Dynamics PD618SA - Professional 18-inch 1400W Active Subwoofer
The Power Dynamics PD618SA is a high-performance active subwoofer designed for sound professionals seeking deep, powerful, and accurate bass response. Part of the acclaimed PD6 series, this subwoofer is built to the highest quality standards, utilizing a robust plywood enclosure that minimizes unwanted resonances and ensures exceptional durability. Its textured black paint finish and rubberized coating effectively protect it against the rigors of transport and continuous use on tour, making it the perfect choice for rental companies, stages, mobile DJs, and large-scale events.
At the heart of the PD618SA is a powerful, high-efficiency Class-D amplifier capable of delivering 500W of continuous RMS power and peak power up to 1400W. This amplifier powers an imposing 18-inch ferrite magnet woofer, designed to move large volumes of air and generate a maximum sound pressure level of 130 dB. The result is a punchy, defined bass that adds the impact and depth needed for any music production.
Main Features
-
Class-D Amplifier: Provides 500W RMS (1400W peak) of clean and efficient power, with less weight and heat generation.
-
18-Inch Woofer: A large diameter transducer that ensures solid and deep low-frequency reproduction, from 35 Hz.
-
Integrated Active Crossover: The variable crossover, adjustable between 50 Hz and 150 Hz, allows for seamless integration with satellite speakers, sending only the frequencies it needs to reproduce to each component.
-
Phase Control: A phase switch (0 - 180 degrees) that allows you to acoustically align the subwoofer with the main speakers, avoiding cancellations and ensuring maximum punch.
-
Professional Connectivity: It features balanced line inputs in XLR and 6.3 mm jack format. It includes a "Loop Thru" output to send the complete signal to another subwoofer and a filtered "High Pass" output to directly connect active satellites.
-
Robust Construction: Housing made of high-density plywood with a textured protective coating, integrated handles and a 35mm post mounting socket.
Benefits for the Sound Professional
The PD618SA's intelligent design translates into direct benefits for both the technician and the performer. The ability to adjust the crossover point and phase directly on the rear panel greatly simplifies PA system setup, eliminating the need for external processors. Its Class-D amplifier not only ensures reliable performance night after night but also makes the unit lighter, facilitating transport and setup. Its robust construction guarantees a long-lasting investment, capable of withstanding the demands of intensive professional use.
Use Cases
Thanks to its power and versatility, the Power Dynamics PD618SA is the ideal solution for a wide range of applications:
-
Live Sound: Provides the essential bass foundation for bands in concert halls, festivals, and outdoor events.
- Mobile DJs and Discos: Offers the impact and energy that electronic and urban music demands, filling the dance floor with deep bass.
- Fixed Installations: Perfect for reinforcing the sound system in theaters, auditoriums, places of worship and convention centers.
- Rental Companies: Its reliability, robust construction and ease of setup make it a profitable and highly demanded asset.
Frequently Asked Questions
Do I need an external amplifier for this subwoofer?
No. The PD618SA is an active subwoofer, which means it has its own built-in amplifier. You just need to connect it to a signal source (like a mixing console) and a power outlet.
How do I connect my main (satellite) speakers?
You can connect the output of your mixer to the input of the PD618SA. Then, use the subwoofer's XLR "High Pass" output to send the filtered (bass-free) signal to your active satellite speakers. This optimizes the performance of the entire system.
What is phase control used for?
Phase control helps synchronize the subwoofer's sound wave with that of the main speakers. Proper phase alignment ensures that the bass frequencies don't cancel each other out and instead blend correctly, resulting in a more coherent and impactful sound.
Can I use more than one subwoofer?
Yes. You can use the "Loop Thru" output to send the full audio signal to a second PD618SA subwoofer, allowing you to easily scale the bass system for larger events.
