Main Features
-
Powerful 18-Inch Woofer: Equipped with a large diameter (18") speaker and a 3" voice coil, the PDY218SA is capable of moving large volumes of air to generate deep and powerful bass, covering a frequency range from 30Hz to 250Hz.
-
Efficient Class D Amplification: It integrates a Class D amplifier that delivers up to 1000W of peak power (500W RMS). This technology ensures high performance with low distortion, minimal heat generation, and a lighter weight, ideal for mobile applications.
-
Total Signal Control: It features an adjustable crossover between 80Hz and 150Hz, allowing for seamless integration with satellite speakers. Furthermore, phase control (0-180°) helps align the subwoofer's response with the rest of the system, preventing cancellations and maximizing sonic impact.
-
Protection and Reliability: It incorporates a digital signal limiter with an LED indicator that protects the speaker from spikes and overloads, ensuring safe operation and a long lifespan. The delayed soft-start system protects internal components during power-up.
-
Professional and Versatile Connectivity: Offers multiple input options, including balanced XLR, RCA and 6.3 mm jack connectors, making it easy to connect from mixing consoles, DJ controllers or other audio sources.
-
System Expansion Outputs: It has an XLR "Loop Through" output to send the signal to a second subwoofer and a "High Pass" output that filters low frequencies to power active satellite speakers, optimizing the overall performance of the sound system.
-
Rugged Construction for Touring: The enclosure is constructed from high-density plywood with an extra-resistant finish that resists scratches and impacts. It includes side handles for easy transport and a 35mm socket (Top Hat) on top for mounting a speaker pole.

Frequently Asked Questions
Do I need an external amplifier for this subwoofer?
No, the PDY218SA is an active subwoofer, which means it has its own built-in amplifier. You just need to connect it to a power source and an audio signal source.
What type of speakers can I connect to the High-Pass output?
You can connect any active full-range speaker (satellite). The High-Pass output will send the filtered audio signal (without the low frequencies reproduced by the subwoofer), allowing the satellites to work more efficiently and cleanly.
How do I connect two PDY218SA subwoofers together?
You can connect the signal source to the first subwoofer and then use the XLR "Loop Through" output of the first one to send the complete signal to the second subwoofer.
What is phase control used for?
The phase control (0-180°) allows you to adjust the timing of the subwoofer's sound wave so that it is perfectly synchronized with that of the main speakers. Proper phase alignment prevents frequency cancellations and ensures that the bass is perceived with maximum punch and clarity.
