SW 1218A<\/strong><\/h3>\n

Low-frequency power for high-demand systems<\/h4>\n

O SW 1218A<\/strong> It was developed to extend the low-frequency response of professional systems, delivering high sound pressure levels and extended bass on an integrated platform.<\/p>\n

Equipped with two 18-inch speakers with 3-inch voice coils<\/strong>, the SW 1218A is designed to reproduce the bass range with power and consistency, making it a suitable solution for systems that require impact and presence at low frequencies.<\/p>\n

More than just a subwoofer<\/h4>\n

The performance of a subwoofer system does not depend solely on the amount of available power. Controlling that power is essential for achieving a consistent response and proper integration with the rest of the system.<\/p>\n

For this reason, the SW 1218A features 48 kHz, 24-bit DSP<\/strong>, allowing the signal parameters to be processed before the signal is sent to the speakers.<\/p>\n

Integrated processing works in conjunction with amplification and transducers, forming a platform designed to operate as a single system.<\/p>\n

Two 18-inch speakers. A single platform<\/h4>\n

The configuration with two 18-inch speakers<\/strong> It allows the SW 1218A to move a large volume of air, providing the power needed for applications that require a powerful bass response.<\/p>\n

With a frequency response of 30 Hz to 200 Hz<\/strong>, the system is capable of covering a wide range of low frequencies, allowing it to be used as an extension of main systems in various sound reinforcement configurations.<\/p>\n

Power Under Control<\/h4>\n

The SW 1218A uses amplification Class D<\/strong>, with 1,000 W RMS and up to 2,000 W of peak power<\/strong>. The built-in amplifier eliminates the need for a dedicated external subwoofer amplifier and keeps the electronics directly connected to the drivers.<\/p>\n

This architecture simplifies system implementation and allows the amplifier, processor, and speakers to operate within a single platform.<\/p>\n

Designed for sound pressure<\/h4>\n

With 131 dB maximum SPL<\/strong>, the SW 1218A is designed for applications that require high sound pressure levels at low frequencies.<\/p>\n

Its design combines acoustic capabilities, amplification, and processing to deliver not only more bass, but serious, yet controlled and consistent<\/strong>.<\/p>\n

The subwoofer as part of the system<\/h4>\n

A subwoofer does not exist in isolation. Its function is to complement the main system, extending its low-frequency response and allowing the other components to operate within their respective frequency ranges.<\/p>\n

The SW 1218A was developed with this system vision in mind: a subwoofer platform capable of integrating into different setups and delivering the power needed to take the audio experience to a whole new level.<\/p>\n

More reach. More pressure. More impact.<\/strong><\/p>\n

SW 1218A \u2014 designed to bring the entire system to life.<\/strong><\/p>\n

Comes with:<\/p>\n
