Serious Low-End for Demanding Performances

BIG SOUND, BIG VALUE
The SXA18p is an 18” vented line array subwoofer capable of handling the most demanding performances. When combined with one or more Alto Professional SXA28p speakers, this powerhouse subwoofer is engineered to deliver a nearly limitless array of configuration options, allowing you to easily incorporate it with as up to four SXA28p loudspeakers as needed for any short or medium throw environment. The SXA18p is also built to endure the rigors of the road night after night, while maintaining a sound that is loud, clean and uncolored. As part of Alto Professional's TOURMAX ARRAY series, the SX18p is part of the most remarkable value in component speaker arrays in the industry.

BRING ON THE POWER
With the ability to handle 750 watts Continuous, 1500 watts Program or 3000 watts Peak, the SXA18p is ideal for obtaining clean, deep frequencies. Capable of delivering 125 dB Peak SPL, the SXA18p packs serious punch for any performance. No matter how big or small the gig may be, the SXA18p can handle the job and produce incredible sonic clarity.

BUILT FOR THE RIGORS OF THE STAGE
The SXA18p has a rugged cabinet made of 18mm calibrated plywood that is ready for the constant abuse that touring systems endure on a daily basis. The sleek black finish and perforated metal grill make sure it is heard, not seen, so audiences stay focused on the performance. Whether on stage, on the road or in a house of worship, the SXA18p delivers flexible, powerful sound for a remarkable value.

Suggested configurations include 2 × SXA18P subwoofers usable from 37Hz at 180Hz, plus 4 × SXA28P speakers usable from 77Hz at 18kHz and one STAGEDRIVE+ Digital Processor that includes factory presets and user memory for custom presets.
