Vonyx SWA15 - 15" Active PA Subwoofer with Adjustable Filter and 600W Power
The Vonyx SWA15 is a high-performance bass reinforcement solution designed to transform standard sound systems into complete and powerful audio setups. This 15-inch active subwoofer eliminates the need for external amplifiers thanks to its integrated, high-efficiency amplification module, capable of delivering a maximum power of 600W (300W output power). It's the ideal component for mobile DJs, bands, and event organizers looking to add depth and body to their music without complicated technical setups.
Its "Plug & Play" design allows for immediate integration with existing active or passive speakers. By incorporating a fully adjustable low-pass filter, the user has complete control over the crossover frequency, allowing the subwoofer to handle the deepest bass frequencies exclusively, freeing the satellite speakers (tops) to reproduce mids and highs with greater clarity and definition. The robust acoustic carpet finish and metal front grille ensure that the system can withstand the rigors of transport and continuous use on stages and at parties.
Main features
-
Power and performance: Equipped with a 15-inch high-excursion woofer and an internal amplifier that generates a maximum sound pressure (SPL) of 115dB, ensuring bass that you can physically feel.
-
Adjustable Low-Pass Filter: Features a dedicated rotary control that allows you to adjust the operating frequency range between 30Hz and 120Hz . This is vital for "tuning" the subwoofer to the main speakers and avoiding unwanted frequency overlap.
-
Phase Control: Includes a phase switch (0° - 180°). This professional feature corrects wave cancellation problems when the subwoofer and main speakers are placed in different positions, ensuring that the bass reaches the audience with maximum power.
-
Versatile Connectivity: It features XLR and RCA inputs, ensuring compatibility with virtually any mixer, DJ controller, or audio source. Additionally, its THRU output facilitates daisy-chaining multiple subwoofers for larger setups.
-
Road-ready construction: The enclosure is covered with wear-resistant carpeting and features protective corner guards. It incorporates side handles for ergonomic transport and a top hat for mounting satellite speakers using a spreader bar.
Benefits of the SWA15 active system
Adding the Vonyx SWA15 to your existing setup offers an immediate improvement in perceived sound quality . By delegating the low frequencies (the "punch" and resonance) to this dedicated subwoofer, your main speakers don't have to work hard to reproduce sounds they aren't optimized for. This results in a cleaner overall sound, with clearer vocals and higher overall volume without distortion. Furthermore, its active nature simplifies installation: you only need a signal cable and a power outlet, saving space in amplifier racks.
Recommended use cases
-
Mobile DJs and Discomobiles: Perfect for adding the necessary punch in genres such as electronic music, reggaeton or hip-hop at weddings and private parties.
-
Small Bands and Live Performances: Ideal for reinforcing the bass drum and electric bass in small venues, bars or rehearsal rooms.
-
Karaoke and Home Party Systems: Enhance the entertainment experience by providing cinematic or club-style sound.
-
Presentations and Corporate Events: Adds depth to background music and multimedia presentations in medium-sized auditoriums.
Frequently Asked Questions
-
Do I need an external amplifier for this subwoofer?
No, the Vonyx SWA15 is active, meaning it already has the amplifier built into the box. You just need to plug it into a power outlet and send it an audio signal from your mixing console.
-
What is the purpose of the phase switch?
Sound travels in waves. Sometimes, the subwoofer's wave and the speakers' wave can "collide" and cancel each other out (the bass disappears). The phase switch inverts the subwoofer's wave to align it with the speakers and restore the bass's power.
-
Can I connect my speakers directly to the subwoofer?
The SWA15 has "THRU" outputs that copy the input signal. You can use these outputs to send the signal to your active speakers. If your speakers are passive, they will need their own separate amplifier.
-
What is the "Top Hat" or top glass?
It's a standard hole on the top of the subwoofer that allows you to insert a bar (not included) to place your main speaker right on top of the sub, creating a compact and aesthetically pleasing sound tower.
