Vonyx SWP18 PRO - 18" Active Subwoofer with Adjustable Low Pass Filter
The Vonyx SWP18 PRO is a high-performance sound reinforcement solution designed for audio professionals and enthusiasts looking to add powerful depth to their PA setups. This active subwoofer features an impressive 18-inch woofer , capable of moving large volumes of air to generate dense, vibrant bass that can be felt throughout the room. With a maximum power output of 1200W , this system delivers the necessary punch for live events, DJ sets, and sound reinforcement in medium to large venues.
Unlike standard subwoofers, the Vonyx PRO model stands out for its active and adjustable low-pass filter . This feature allows the user to precisely select the crossover frequency range between 40Hz and 250Hz . Thanks to this functionality, it's possible to achieve perfect acoustic integration with satellite or full-range speakers, ensuring that the subwoofer handles only the frequencies it reproduces best, freeing the main speakers from the bass load and improving the overall clarity of the system.
The cabinet's construction has been meticulously designed to withstand the demands of professional use. Made from high-density MDF, it offers a rigid structure that minimizes unwanted vibrations and eliminates internal resonance, delivering a clean, distortion-free sound. Furthermore, its exterior finish features a hardened epoxy coating , an extra-resistant layer that protects the unit against bumps, scratches, and the wear and tear typical of touring and mobile events.
Main Features
-
High Power Amplification: Integrated 1200W peak (600W RMS) amplifier module, designed to deliver sustained high performance without the need for external power stages.
-
Total Frequency Control: The adjustable active low-pass filter allows you to fine-tune the frequency cutoff between 40Hz and 250Hz to suit any musical genre or room acoustics.
-
Phase Management: Includes a switchable phase switch (0º - 180º) to temporarily synchronize the sound wave with the main speakers, avoiding frequency cancellations and ensuring that the bass reaches the audience with maximum impact.
-
Versatile Connectivity: Equipped with dual XLR and RCA inputs and outputs, facilitating daisy-chaining (linking) with other subwoofers or amplifiers, allowing for complex mono or stereo configurations.
-
Design for Transport: The handles integrated into the wooden casing itself facilitate handling and loading of the equipment, while its high-resistance coating ensures its long-term durability.
Benefits of the Vonyx SWP18 PRO
Integrating the Vonyx SWP18 PRO into your sound system radically transforms the listening experience. Its main benefit lies in its signal-to-noise ratio of over 120dB , resulting in a quiet background and highly accurate dynamic reproduction. As an active system, it greatly simplifies setup, eliminating the need for impedance calculations or lugging around heavy amplifier racks; it's a professional "Plug & Play" system.
Furthermore, the inclusion of a tripod mount (Top Hat) at the top is a crucial logistical advantage. It allows a satellite speaker to be mounted directly on top of the subwoofer using a spacer bar, saving floor space and creating an aesthetically clean and acoustically aligned sound tower.
Use Cases
-
Mobile DJs and Events: Ideal for mobile discos that need to transport their own equipment and require bass that fills the dance floor without technical complications.
-
Live Bands: Perfect for reinforcing the bass drum and electric bass in performances in bars, small concert halls or outdoor events.
-
Fixed Installations: Gyms, pubs or clubs looking for a permanent sound installation with a deep and reliable bass response.
-
Conferences and Presentations: Adds body and presence to background music and sound effects in high-impact corporate presentations.
Frequently Asked Questions
Do I need an external amplifier to use this subwoofer?
No, the Vonyx SWP18 PRO is an active subwoofer, meaning it already has a built-in amplifier. You just need to plug it into a power outlet and send the audio signal from your mixer or controller.
How should I configure the low-pass filter?
It will depend on your main speakers. If your speakers are small (8-10 inches), you can adjust the crossover point to 100Hz-120Hz. If you use larger speakers (12-15 inches), you can lower the crossover point to 80Hz. The idea is for the subwoofer to cover the frequencies that your main speakers don't produce strongly.
Can I connect two SWP18 PRO subwoofers together?
Yes, thanks to its "Thru" output connections (RCA or XLR), you can send the signal from one subwoofer to another, allowing you to set up systems with double subwoofers for greater sound pressure.
