The Mackie Thump18Sv4 is an active 18" PA subwoofer for users who need even more depth and sound pressure in their sound reinforcement system. Equipped with an 18" high-performance woofer and a powerful 1,400 watt Class-D power amplifier, this model delivers a superior bass foundation for live sound reinforcement, DJ setups, club applications and events. With a frequency range of 25 Hz to 160 Hz and a maximum sound pressure level of 132 dB SPL, the Thump18Sv4 is designed for powerful yet controlled bass reproduction.
For optimum integration into different PA setups, the subwoofer offers a switchable crossover frequency with presets for 140 Hz for the Thump12v4, 110 Hz for the Thump15v4 and 150 Hz for the Thump GO. In addition, the crossover frequency can be variably adjusted so that other tops can also be connected appropriately. A phase reverse switch and a mono/stereo switch extend the customization options and help to ensure that the overall system is perfectly matched.
On the connection side, the Mackie Thump18Sv4 is set up professionally and practically. It has two balanced XLR inputs and four balanced XLR outputs, including two full-range and two high-pass outputs. This allows the subwoofer to be versatilely integrated into various signal paths. An input gain control and an overload LED are available for easy everyday operation. Peak and RMS limiters as well as a temperature protection circuit are also integrated to protect the electronics and speaker equipment, which supports reliable operation even at higher levels.
Despite its performance, the Thump18Sv4 is designed for practical use. Integrated carrying handles make transportation easier, the front LED can be switched off if required and an optional SPM400 distance rod can be used to mount a top section via the M20 thread. This makes the Mackie Thump18Sv4 a convincing choice for anyone looking for a powerful active subwoofer with high practical suitability, flexible system adaptation and powerful bass performance.
