Subwoofer Omnitronic AZX-115 — 400W power, 15-inch driver

The Omnitronic AZX-115 active subwoofer delivers 400W continuous power through a 15-inch driver to reinforce low frequencies for PA systems, clubs and live events. Designed to reproduce deep bass with controlled impact, this compact subwoofer integrates into DJ rigs, small-to-medium venue sound systems and permanent installations where reliable low-end extension is required. The robust enclosure and practical footprint simplify transport and stage placement while maintaining consistent performance during repeated use.

Advantages

The AZX-115 combines a high-power amplifier with a 15-inch transducer to provide precise bass reproduction and strong low-frequency output. Its construction balances portability and durability for regular handling and stage use. Built-in signal routing and level control options enable straightforward integration with mixers, full-range speakers and DJ equipment. The design emphasizes stable performance and predictable frequency response across typical live and installation scenarios.

How to use

Place the AZX-115 on a stable surface or use it as a flown or stacked element within a PA array according to venue and stage setup. Connect the mixer or DJ controller to the subwoofer line inputs and route the subwoofer output to full-range speakers if required. Adjust the level control and crossover settings so the subwoofer blends smoothly with the main speakers, avoiding excessive overlap that could cause muddiness. For live events, start with conservative gain settings and increase gradually while monitoring bass balance in the listening area.

Recommendations

Position the subwoofer near the front-of-house or stage edge for even bass coverage, and allow space for the ported enclosure to operate without obstruction. Use the built-in crossover to set a clear transition between the subwoofer and main speakers—typical crossover points range between 80–120 Hz depending on the other system components. Regularly inspect connectors and cabinet hardware before transport and use moderate levels to prolong driver life.
