HK Audio PSUB-118A

A Subwoofer Designed for the PORTABLE SOUND Family: Range Consistency and "Plug & Play" Logic

The HK Audio PORTABLE SUB 118 A is part of the PORTABLE SUB series, developed to work seamlessly with LUNAR, SONAR, and POLAR MK2 speakers. The concept is simple: a single format, a clear usage concept, and a consistent sound signature to quickly assemble a complete system without hassle.

Within the range, HK Audio offers two models: the PORTABLE SUB 115 A (more compact and direct orientation) and the PORTABLE SUB 118 A, chosen when seeking more foundation and a sensation of deeper bass. The result: a subwoofer designed to provide a solid base for high-performance setups, whether solo or as reinforcement for a 2.1 system.

For Whom and For What Uses: Musicians, DJs, Service Providers, and Rentals

This active subwoofer is an excellent choice if you want to strengthen the low end without complicating your setup. For a DJ, it guarantees a firmer kick, clearer bass, and a track that "breathes." For a band, it adds body to keyboards, sequences, and kick drums while maintaining clean articulation.

The PORTABLE SUB 118 A also targets service providers and rental fleets: its "ready-to-play" operation, quick settings, and ergonomic transport make it a reliable tool when fast setup, operation, and teardown are required. Thanks to its matching design, it integrates naturally with HK Audio PORTABLE SOUND series systems.

Control, DSP, and Integration: Clean, Tuned Bass That's Easy to Use

24-bit DSP: Presets That Save Time (and Improve Quality)

The 24-bit DSP is not there to add unnecessary menus: it provides automatically consistent tuning with the selected speaker via presets perfectly matched for LUNAR, SONAR, and POLAR MK2. The benefits include more natural phase alignment, better bass control, and improved impulse fidelity for a "crisper," more controlled low end.

Stereo 2.1 Preamplifier: Architecture Designed for the Field

The PORTABLE SUB 118 A features a stereo preamplifier suited for 2.1 systems, with a clear logic: input / thru, gain control, and a polarity switch. These simple but essential functions allow quick adaptation of the subwoofer to the room, placement, and the rest of the sound system without adding extra devices.

Powerful and Silent Amplification: Fanless, No Compromise

With 1,400 watts (peak), this active subwoofer has the reserve needed to handle realistic dynamics. Its fanless amplification design is especially appreciated in demanding environments: no fan noise, no mechanical sounds, just the power needed to drive the bass.

Robust Wooden Enclosure and MultiGrip Handles: Safer Transport, "Tighter" Bass

Built around a compact and sturdy wooden enclosure, designed for dry, controlled reproduction. The MultiGrip handles provide a secure and ergonomic grip, a real advantage when handling multiple loads or stairs. Finally, the design remains elegant and consistent with other elements of the series.

The PORTABLE SUB 118 A is Made in Germany and comes with a 5-year warranty after registration, offering peace of mind for regular or professional use.
