Introducing the New Avante Audio Imperio Pro IMP118 Single 18-inch Active Subwoofer

Christian Wissmuller • Sound Reinforcement • March 26, 2024

Powerful, versatile, compact, and reliable, the new Imperio Pro IMP118 active subwoofer from professional audio manufacturer AVANTE Audio is now shipping. Featuring high quality components, precision audio engineering, a robust enclosure, a powerful integrated amplifier, and a flexible internal DSP, it delivers high quality low frequency audio output suitable for a range of applications. With a variety of hardware options, it can be deployed in numerous configurations for medium-to-large-scale concerts, parties and events.

At the heart of the Imperio Pro IMP118 is a powerful 18-inch high-power transducer driven by a high-energy 4-inch (100mm) voice coil motor assembly. It is implemented through an efficient bass-reflex system design to deliver exceptionally linear frequency response from 32Hz – 130 Hz (-10dB) / 38 Hz -130Hz (-3dB) with a maximum SPL of 136 dB (peak). An integrated 3600-Watt (peak) Class-D power amplifier provides ample headroom and minimizes distortion, ensuring highly responsive deep sub bass output.

The enclosure is also fitted with an advanced DSP system that allows configuration for a wide variety of different applications and speaker arrangements. Access to the DSP settings is provided via a large backlit LCD display on the rear panel. An intuitive menu interface allows quick and easy setup, which is navigated using a single push-to-select rotary control.

DSP presets are provided for normal solo cabinet deployment as well as more advanced cardioid and end-fire coverage control patterns using multiple cabinets. The DSP also features FIR filters for accurate LP-crossover settings that can be configured to 60 Hz, 70Hz, 80 Hz, 90 Hz, 100 Hz or 120 Hz. The menu interface can also be used to reverse the driver polarity, enter a delay time / distance and alter the volume level to optimize the signal gain structure.

The enclosure is designed to withstand the rigors of professional touring applications. Constructed from premium CNC-machined Birch plywood, it has a sleek black polyurea finish that is very durable as well as a black powder coated steel grille to protect the speaker cone. It is fitted with a pair of recessed carry handles on the sides and features an XLR input socket alongside an XLR output for linking together additional active speakers. Power is supplied via a locking IP65-rated socket, which can’t become accidentally disconnected during use. A locking IP65-rated output link socket is also provided, allowing the power supply for multiple speakers to be ‘daisy chained’ from a single outlet. The unit can be used globally as it is compatible with a power supply of 100~240V AC 50/60Hz. A protective rain cover is also provided for the amplifier panel and connection sockets, allowing for safe use outdoors in wet conditions.

A variety of integrated hardware accessories allow for versatile deployment. Firstly, a standard M20 threaded speaker pole slot is located on the top of the cabinet to allow a mid/top cabinet (for example one of AVANTE Audio’s Achromic X Series models) or small configuration of Imperio Pro IMP205compact line array modules to be mounted above. The bottom of the cabinet is also fitted with skids, which fit into corresponding shallow recesses on the top for when multiple units are stacked. A convenient spring-loaded locking system then allows the cabinets to be secured together without the need for straps or any other additional hardware. Finally, the cabinet is fitted with 20 captive nut M10 fly points for applications that require the speaker to be permanently mounted overhead.

Weighing in at 101 lbs. / 45.8 kgs., the unit can be easily managed by one or two people. To allow convenient transportation, a dedicated caster board (Imperio Pro IMC118) is available as an optional accessory. This locks securely to the bottom or the front of the cabinet, with the later option covering the speaker grille to provide added protection during transportation and storage.

“The result of years of R&D and extensive real-world field testing, the Imperio Pro IMP118 is an 18-inch active sub that meets every expectation of audio professionals,” enthuses Avante Audio’s Product Engineer, Tony Mirador. “It combines a powerful Class D amplifier with a versatile DSP and premium speaker driver with a large 4” voice coil to deliver exceptional output. Meanwhile, its tough construction and versatile design – complete with useful interlocking stacking hardware – means that it is ready for life on the road. Featuring premium components and an efficient bass-reflex design, the Imperio Pro IMP118 produces high output, low-frequency energy that you can truly feel.”

The Avante Audio Imperio Pro IMP118 is shipping now in the Americas and will be available in Europe from late March 2024.
