## Long description

The Bitmat DNA SPX18 SUB is an active 18-inch subwoofer with integrated DSP and 600W of onboard amplification, engineered to reproduce deep low-frequency sound for PA systems, clubs and fixed installations. Designed for reinforcement of music and live sound, this subwoofer provides focused sub-bass extension while allowing on-site adjustment of level, crossover and protection settings through its digital signal processing. The enclosure and driver are tuned to deliver controlled low-end output suitable for stage, event and venue use.
Advantages
This active subwoofer combines a high-power amplifier and built-in DSP to simplify system setup and reduce the need for external electronics. The large 18-inch driver delivers extended bass response and high acoustic output, while the DSP provides precise control over level, crossover frequency and protection parameters to protect the driver and maintain consistent performance. The integrated design reduces cabling and rack space requirements compared with separate amplifier and processor solutions.
Suitable for
 Public address systems and live sound reinforcement
 Nightclubs and DJ setups requiring strong sub-bass
 Fixed installations in venues, bars and houses of worship
 Portable PA systems for events and small concerts
Key specifications
 Speaker size: 18-inch low-frequency driver
 Amplifier power: 600 watts (integrated)
 Processing: on-board digital signal processor for level, crossover and protection adjustment
 Application: active sub-bass reinforcement for PA, clubs and installations
 Enclosure: ported or sealed design tuned for low-frequency extension (as provided by manufacturer)
How to use
Place the subwoofer on stable ground or on a stage riser, ensuring correct orientation and sufficient ventilation for the amplifier. Connect input sources from the mixing console or signal processor using appropriate balanced or line-level connections. Set initial gain and crossover values via the onboard DSP, monitoring levels to avoid clipping. Adjust phase and level relative to main loudspeakers to achieve coherent low-frequency response, then fine-tune crossover frequency and output level for the room or event. Use built-in protection settings to prevent over-excursion and thermal overload during extended use.
Usage recommendations
 For consistent performance, position the subwoofer to minimize boundary reinforcement that causes boomy bass, and perform listening checks at typical audience positions while adjusting the DSP crossover and level. When deploying multiple units, use time alignment and level matching to maintain even low-frequency coverage across the listening area.
