Vonyx SMWBA18 - 18" 1000W Bi-Amplified Active Subwoofer
The Vonyx SMWBA18 isn't just a subwoofer; it's the beating heart of a complete and powerful sound system. Designed to offer an all-in-one solution for mobile DJs, event organizers, and entertainment venues, this 18-inch active subwoofer stands out thanks to its impressive bi-amplified technology . Unlike conventional subwoofers that are self-powered, the SMWBA18 incorporates an internal three-channel amplifier: one dedicated exclusively to managing its 500W of bass power, and two independent 250W channels each designed to directly power a pair of passive satellite speakers. This eliminates the need to carry additional external amplifiers, drastically simplifying setup and wiring.
Sound quality is guaranteed thanks to its high-performance 18-inch woofer, capable of moving large volumes of air to generate powerful sound pressure and deep, chest-filling bass. With an operating frequency range in the sub-bass from 20Hz to 200Hz , this system ensures that low frequencies have the presence and definition necessary for demanding musical genres such as electronic, hip-hop, and dance music. Furthermore, its robust construction is designed for the road: a solid cabinet covered in wear-resistant acoustic carpet, protected corners, and a metal front grille that shields the cone from accidental impacts during transport or performance.
The Vonyx SMWBA18's versatility extends to its rear control panel, designed to adapt to a wide range of situations. It includes an integrated mixer with stereo line inputs for connecting mixing consoles, computers, or players, and a dedicated microphone input. This latter feature is essential for karaoke events or presentations, as it includes an adjustable Echo effect, allowing vocalists to add depth to their voices without the need for external effects processors. Bass and treble controls allow you to equalize the overall output to tailor the sound to the room's acoustics, ensuring optimal listening performance at all times.

Frequently Asked Questions
Can I connect any speaker to the satellite outputs?
Yes, you can connect passive speakers (without their own amplifier) rated at 8 ohms. Make sure the power handling of the speakers is compatible with the amplifier's 250W output to avoid damage.
Is an external crossover necessary?
No, the SMWBA18 already manages the frequencies internally. The subwoofer reproduces the low frequencies (up to 200Hz) and sends the rest of the audio spectrum to the satellite outputs, ensuring balanced sound.
What type of maintenance does carpet finishes require?
The finish is very durable and built to last. Generally, occasional vacuuming or gentle brushing is enough to keep it dust-free and looking new.
