BASSBOSS SSP118-MK3 - 2500W 18-inch Powered Vented Direct Radiating Subwoofer with 4.5-inch Voice Coil and 360-Degree Coverage in Black Finish

The BASSBOSS SSP118-MK3 is a powerful, compact 18-inch powered subwoofer designed to deliver deep, low-frequency output with remarkable efficiency and precision. Perfect for mobile professionals, touring sound systems, and venues with limited space, the SSP118-MK3 provides impressive bass performance in a manageable, portable form factor. With a frequency response extending from 30Hz to 100Hz (+3 dB), this subwoofer offers an ideal solution for those looking for high output, superior sound quality, and the ability to cover a wide range of low-end frequencies with ease.

Weighing just 125 lbs and measuring 22.5 x 30 x 24 inches, the SSP118-MK3 provides exceptional output at 136 dB peak SPL, with sustained output levels reaching 130 dB SPL at 1 meter, ground plane. The subwoofer is powered by a 2500W Class-D amplifier with a global auto-sensing power supply, capable of running on mains voltages anywhere between 90V and 250V. This wide voltage compatibility ensures the subwoofer can be used in various locations around the world, with full power available for anything over 110V. The amplifier's high peak-output voltage provides dynamic power for impactful bass hits, while its sustained output delivers liquid lows with remarkable clarity.

At the heart of the SSP118-MK3 is a robust 18-inch, neodymium motor woofer with a 4.5-inch voice coil and a 56mm peak-to-peak excursion. The neodymium magnet ensures a lighter, more efficient design compared to traditional ferrite drivers, resulting in both a louder and lighter cabinet. The woofer is housed in a vented enclosure, optimized to maximize low-frequency output through a large port that enhances air movement for deeper bass response. The port is engineered to minimize noise and distortion while allowing for efficient cooling, ensuring reliable performance even during prolonged use. When necessary, two blower fans engage to provide additional cooling, preventing thermal overload and ensuring optimal operation in demanding conditions.

Integrating advanced digital signal processing (DSP), the SSP118-MK3 delivers flawless performance with precise control over low-frequency response. The DSP includes high-pass and low-pass filters, phase alignment, and multi-stage limiting, offering protection from thermal damage, excessive excursion, and clipping. The sophisticated five-level protection system minimizes long-term thermal compression, reduces driver overload, and ensures the subwoofer performs optimally, even at peak output levels. Additionally, the DSP features up to 100 presets, with eight directly accessible presets that are compatible with other BASSBOSS MK3 series top boxes and subs, allowing for easy integration and customization.

The SSP118-MK3 is housed in a rugged, CNC-machined Baltic Birch plywood cabinet, constructed using dado and rabbet joinery for strength and durability. The cabinet is coated with a high-pressure polyurethane finish, making it resistant to weather and environmental wear, making the subwoofer ideal for both indoor and outdoor applications. The integrated, powder-coated steel grille protects the woofer and enhances midrange dispersion. With four integrated handles for easy transport, four interlocking rubber feet, and a 35mm pole socket for mounting, the SSP118-MK3 is designed for flexibility, convenience, and reliability on the go.

In addition to its portable design, the SSP118-MK3 features 16 M10 threaded fly points for easy rigging and mounting, ensuring that it can be flown or ground-stacked as needed for different setups. The cabinet's design also allows for seamless integration with other BASSBOSS loudspeakers, offering a complete sound system solution for events of any size. Whether you're a DJ, sound engineer, or venue owner, the BASSBOSS SSP118-MK3 is the perfect choice for delivering deep, powerful bass with outstanding clarity and reliability.
