Active subwoofer Omnitronic 11038870

The Omnitronic 11038870 is an active subwoofer designed to extend low-frequency response for home and small professional audio systems. It delivers a continuous 300 W RMS to reproduce deep bass notes down to 45 Hz, with an upper range reaching 250 Hz for seamless integration with midrange speakers. Built with a robust MDF cabinet and a compact footprint (30 cm W × 47 cm D × 43 cm H), this subwoofer balances performance and space efficiency while operating from standard AC power.

Advantages

This active subwoofer provides reliable low-frequency output with a rated 300 W RMS, enabling consistent bass reproduction at moderate to high listening levels. The MDF enclosure reduces unwanted resonance and improves tonal stability. Its frequency range of 45–250 Hz makes it suitable for both music and film content, and the compact dimensions allow placement in tight spaces without compromising sound quality. The unit’s AC-powered design and reasonable power consumption make it compatible with commonly used home audio setups.

How to use

Place the subwoofer close to a wall or in a corner for increased low-frequency reinforcement, taking care to allow ventilation around the cabinet. Connect the subwoofer to your audio system using the appropriate line-level or speaker-level inputs as available on your system; set crossover and level controls on the subwoofer or on the system to blend it with the main speakers, aiming for a natural transition around the upper frequency limit. Operate the unit from a grounded AC outlet and follow basic safety precautions such as avoiding exposure to moisture and extreme heat.

Recommendations

For balanced bass performance, start with the crossover set near 80–120 Hz and adjust the level so that bass is present but not overpowering. When placing the subwoofer, test a few positions while listening to familiar material to find the best integration with your main speakers. If using in a small room, reduce the level slightly to prevent boominess.
