LAS VEGAS — As the professional audio industry descends upon the Las Vegas Convention Center for InfoComm 2026, the buzz surrounding the exhibition floor is palpable. Among the myriad of announcements, German audio engineering stalwart HK Audio has made a significant splash with the global debut of two new, highly anticipated product lines: the LUNAR series of 2-way loudspeakers and the companion PORTABLE SUB series.
Designed to address the evolving demands of mobile DJs, live event performers, and corporate AV integrators, these systems represent a shift toward modular, "smart" audio solutions. By decoupling the design process while ensuring tight integration through advanced digital signal processing (DSP), HK Audio is aiming to provide a versatile ecosystem that remains robust in both small-scale mobile setups and sophisticated professional live applications.
The Core Innovation: Defining the LUNAR Series
At the heart of the new launch is the LUNAR series, a trio of 2-way loudspeakers designed for maximum flexibility. Recognizing that modern sound reinforcement often requires a "Swiss Army knife" approach, HK Audio has engineered the LUNAR units to serve triple duty: as full-range standalone systems, as stage monitors, or as the mid/high-frequency components of a larger, sub-integrated array.
The series is comprised of three models, differentiated by their cone driver sizes: 10-inch, 12-inch, and 15-inch versions. This range allows users to scale their investment according to the venue size and the required output levels.
Engineering for Efficiency
The technical backbone of the LUNAR series is its 32-bit DSP. By incorporating sophisticated Finite Impulse Response (FIR) filtering and phase correction, HK Audio has addressed the common acoustic challenges faced in challenging rooms, such as comb filtering and phase smear. This ensures that even when driven to high sound pressure levels (SPL), the cabinets maintain a transparent, dynamic, and high-impact reproduction.
Furthermore, the integration of Bluetooth True Wireless Stereo (TWS) connectivity marks a nod to the modern requirements of convenience. For the mobile entertainer or the solo performer, the ability to stream high-quality audio wirelessly to a pair of LUNAR speakers without the need for complex cabling simplifies the setup process significantly—a major advantage for those operating on tight schedules.
The Foundation: PORTABLE SUB Series
If the LUNAR speakers are the voice of the system, the new PORTABLE SUB series acts as its foundation. Available in 15-inch and 18-inch configurations, these subwoofers have been engineered not just as a closed ecosystem for LUNAR, but as a universal low-frequency solution for HK Audio’s broader product catalog, including the popular POLAR MK2 and SONAR series.
The Power of Presets
The standout feature of the PORTABLE SUB series is its intelligent preset management. In the world of professional audio, the "crossover point" is often a source of frustration. Mismatched phase responses between a subwoofer and a top box can lead to a "hollow" or "muddy" low-mid frequency response.
HK Audio has solved this by implementing series-specific presets. By selecting the appropriate mode at the touch of a button, the system automatically tunes the crossover and phase alignment to match the characteristics of the specific HK Audio top cabinet being used. For those using speakers from other manufacturers, a "General" preset is available, providing a starting point that can be further adjusted to suit non-proprietary setups.
The internal power plant is equally impressive, delivering up to 1,400 watts of peak power. This translates to a maximum SPL of 131 dB, ensuring that the low-end remains "well-defined" rather than just loud. The integrated stereo preamp simplifies the configuration of 2.1 systems, allowing users to run two LUNAR top cabinets directly from a single subwoofer, further reducing the hardware footprint.
Chronology of Development and Market Entry
The development of the LUNAR and PORTABLE SUB series follows a multi-year R&D cycle at HK Audio’s headquarters. Following the success of the SONAR and POLAR lines, the company identified a gap in the market for a system that provided the durability and sonic pedigree of high-end concert gear, but with the user-friendliness of entry-level portable PA.
- Early 2025: Initial conceptualization of the LUNAR "flexible-use" architecture.
- Late 2025: Beta testing of the FIR filter integration in field conditions across Europe.
- Q1 2026: Finalization of the DSP presets for seamless cross-compatibility with the POLAR and SONAR lines.
- June 2026: Official unveiling at InfoComm 2026, marking the commencement of global distribution.
Supporting Data: Why Scalability Matters
In the current AV climate, the "one-size-fits-all" model is increasingly obsolete. Data from the live sound sector suggests that rental houses and mobile performers are moving away from proprietary, fixed-system investments in favor of modular components.
The LUNAR/PORTABLE SUB combination is a direct response to this trend. By offering three different top-box sizes and two subwoofer sizes, HK Audio allows a single user to build a small, 10-inch "coffee shop" rig on Monday, and combine all components for a 15-inch/18-inch "full-production" gig on Friday. The use of wood cabinetry—rather than injection-molded plastic—suggests a focus on long-term durability, backed by a five-year manufacturer’s warranty, which serves as a significant selling point for cost-conscious professional buyers.
Implications for the Industry
The introduction of these two series signals a wider shift in the professional audio landscape. Manufacturers are no longer just selling "hardware"; they are selling "ecosystems." The ability for a user to plug an existing POLAR MK2 system into a new PORTABLE SUB and achieve an instant, professionally tuned sound via a preset is a major advancement in workflow efficiency.
For the rental and integration market, this reduces the learning curve for staff. When gear is easy to set up and difficult to misconfigure, the likelihood of on-site errors decreases. This is particularly relevant in the post-pandemic live event market, where skilled labor shortages have made "fast and reliable" the gold standard for equipment selection.
Official Perspective and Future Outlook
While HK Audio has remained relatively tight-lipped about the exact pricing tiers for the individual components, their messaging at InfoComm has been clear: "Two independent product lines that work together optimally."
By separating the R&D paths for the top cabinets and the subwoofers, HK Audio has allowed each to reach its maximum performance potential. The LUNAR cabinets are optimized for clarity and midrange punch, while the PORTABLE SUBs are optimized for impulse response and low-frequency depth. When combined, the resulting synergy is designed to bridge the gap between "portable" and "pro."
As attendees at InfoComm 2026 continue to explore the exhibit halls, the LUNAR and PORTABLE SUB series will undoubtedly remain a focal point for those seeking to upgrade their inventory. Whether for a corporate boardroom, a house of worship, or a weekend wedding DJ, the flexibility offered by this new ecosystem is poised to set a new benchmark for mid-market audio performance.
With the official launch now behind them, all eyes are on the field reports that will emerge as these units begin shipping to dealers worldwide. If the initial reception at the convention is any indication, HK Audio has succeeded in creating a scalable, durable, and sonically superior solution that addresses the needs of a diverse range of audio professionals.
For those in attendance at InfoComm, the systems are available for demonstration, allowing engineers and end-users to hear the impact of the 32-bit DSP and FIR filtering firsthand. For those who could not make the trip to Las Vegas, the LUNAR and PORTABLE SUB series are expected to be available through regional distributors starting in late summer 2026.
