- HK Audio is launching two ranges designed for mobile PA: three LUNAR speakers (10″, 12″, 15″) and two PORTABLE SUB subwoofers.
- The concept is the same across the board: ready-to-use presets and immediate hands-on control, with no menus to navigate.
- The LUNAR speakers feature a 32-bit DSP, FIR filter and Bluetooth TWS; the SUBs deliver 1,400 W and tight low-end.
- Everything is compatible at the touch of a button: one preset aligns the subwoofer to your chosen speaker.
We’ve all been there — a soundcheck that drags on while the room fills up. After years of setting up and breaking down systems at Woodbrass, we’ve learned to spot gear that saves time. The new HK Audio LUNAR and PORTABLE SUB ranges are built exactly for that. Their promise: professional sound at the touch of a button, with no endless tweaking. Three active speakers, two subwoofers, one unified concept. Everything you need for a coherent mobile PA system, from bar gigs to mid-sized stages. Here’s a full breakdown of the range, the use cases, and the best pairings between tops and subs.
LUNAR: three active speakers for mobile PA
The LUNAR range is built on a simple idea: get professional results fast. Four presets are stored in the speaker (Music, Monitor, Voice, Subwoofer). You choose the mode, and the voicing adapts to the situation. No sub-menus, no fuss.
On the sound side, the 32-bit DSP with FIR filter and phase correction delivers a clear image and controlled dynamics, even as the volume climbs. Every model includes a combined mic/line input and Bluetooth TWS (True Wireless Stereo), letting you pair two speakers in stereo with no audio cable between them. The cabinet is wood-built, manufactured in Germany, and backed by a 5-year warranty on registration.
The LUNAR 110 XA is the 10" active speaker in the range: compact, easy to carry, and quick to set up. It’s aimed at DJs, musicians, and mobile operators who want a plug-and-play system capable of switching from full-range FOH to stage monitoring.
Its four presets (Music, Monitor, Voice, Subwoofer) cover real-world scenarios, and the 32-bit DSP with FIR filter keeps the sound clear even at high levels. Bluetooth TWS enables wireless stereo between two speakers.

The LUNAR 112 XA is the 12" format in the range — and the most versatile for modern PA. The 12" strikes a natural balance between low-mid presence, punch and clarity, with a crisp transient response ideal for DJ sets and bands.
Like the whole range, it relies on ready-to-use presets (Music, Monitor, Voice, Subwoofer) and a 32-bit FIR DSP with phase correction for a consistent, well-defined sound. Combined mic/line input and Bluetooth TWS round out the connectivity.

The LUNAR 115 XA is the 15" format in the range, focused on power and presence. Standalone, it delivers generous bass and low-mids: perfect when you need punch straight away, without necessarily adding a sub.
Its presets (Music, Monitor, Voice, Subwoofer) switch it from FOH to monitor use in one move. The 32-bit DSP with FIR filter and phase correction ensures clean, dynamic reproduction even at high SPLs.
Pairs with PORTABLE SUB cabinets for extended low-end reach. Wood cabinet, Made in Germany, 5-year warranty (on registration).
All three LUNAR speakers share the same presets, the same Bluetooth TWS and the same hands-on philosophy. Your choice really comes down to driver size: 10″ for portability, 12″ for versatility, 15″ for standalone bass.
PORTABLE SUB: plug-and-play low-end
The PORTABLE SUB cabinets extend the same logic into the low end. Their strength: a 24-bit DSP with presets dedicated to the LUNAR, SONAR and POLAR MK2 ranges. Select the preset that matches your tops, and the sub aligns automatically. A general-purpose preset with a 100 Hz low-pass filter is also available for other systems.
Both models share 1,400 W (peak), fanless Class D amplification and up to 131 dB SPL max. No parasitic noise between tracks — a real asset at cocktail events and corporate functions. Wood cabinet for tight bass, MultiGrip handles, a stereo preamp for 2.1 setups, and input/thru connectivity with gain control and polarity switch.
The PORTABLE SUB 115 A is the compact, punchy active subwoofer in the range, fitted with a 15" driver. It delivers precise, hard-hitting bass up to 131 dB SPL max, powered by a 1,400 W (peak) fanless amplifier.
Its 24-bit DSP offers presets optimised for the LUNAR, SONAR and POLAR MK2 ranges: select your speaker, and the sub aligns automatically. Stereo preamp for 2.1 setups, input/thru connectivity, gain control and polarity switch.
Wood cabinet for tight bass, MultiGrip handles, Made in Germany and 5-year warranty (on registration).
The PORTABLE SUB 118 A is the 18" model in the range, chosen when you want more weight and deeper low-end extension. It targets sets and events with a club vibe: more volume, more pressure in the sub-bass.
It shares the same architecture: 1,400 W (peak), fanless amplification, up to 131 dB SPL max and a 24-bit DSP with presets optimised for LUNAR, SONAR and POLAR MK2. Stereo 2.1 preamp, input/thru, gain control and polarity switch.
Wood cabinet for tight, controlled bass, MultiGrip handles, Made in Germany, 5-year warranty (on registration).
To get started, grab two LUNAR tops and pair them via TWS: you’ve already got genuine wireless stereo. Add a subwoofer later without changing a single setting.
Which PA system should you choose for your use case?
The strength of these two ranges is the ability to build a scalable system. Start light, then expand as your needs grow. Here are a few pairings that make real sense in the field:
- Full-range stereo: 2 × LUNAR 112 XA. The go-to for music and vocals, no sub needed.
- Compact 2.1 system: 2 × LUNAR 110 XA + 1 × PORTABLE SUB 115 A. Lightweight, ideal for adding low-end without the extra bulk.
- Stereo + bass system: 2 × LUNAR 112 XA + 2 × PORTABLE SUB 118 A. The classic setup for DJs and bands, with real energy in the low end.
On a PORTABLE SUB, the polarity switch can fix an unfavourable interaction between sub and tops in two seconds, depending on placement. Try that first if your low-end lacks definition, before touching the gain.
FAQ – HK Audio LUNAR and PORTABLE SUB
Which LUNAR speaker should you choose — the 110, 112 or 115 XA?
It depends on your use case. The 110 XA (10″) prioritises portability and smaller gigs. The 112 XA (12″) is the most versatile and suits the majority of situations. The 115 XA (15″) offers more bass in standalone use, when you need punch without a sub.
Do you need a PORTABLE SUB with a LUNAR speaker?
Not necessarily. The LUNAR speakers work very well full-range on their own, especially the 115 XA. A subwoofer becomes useful when you want more low-end: DJ sets, club-style atmospheres, or larger venues. The speaker’s Subwoofer preset handles the crossover.
How do you pair a PORTABLE SUB with your speakers?
It’s plug-and-play. The sub comes with dedicated presets for the LUNAR, SONAR and POLAR MK2 ranges. Select the one that matches your tops, and the sub aligns automatically. A general-purpose preset with a 100 Hz low-pass covers other systems.
What is the difference between the PORTABLE SUB 115 A and the 118 A?
The 115 A (15″) is compact and punchy, with tight bass and easy portability. The 118 A (18″) delivers more weight and deeper low-end, suited to club-style settings. Both share 1,400 W and up to 131 dB SPL max.
Does Bluetooth TWS provide true wireless stereo?
Yes. True Wireless Stereo (TWS) lets you pair two LUNAR speakers in stereo with no audio cable between them. Stream from a smartphone or tablet — perfect for quick setups, background music or mobile performances.
A mobile PA system built to last
With the LUNAR and PORTABLE SUB ranges, HK Audio has kept the formula simple: professional sound without the complexity, presets that do the heavy lifting, and full compatibility between tops and subs. German manufacturing and a 5-year warranty add the reliability argument — invaluable when you’re running back-to-back gigs.
The next step is figuring out your starting point: a pair of tops for versatility, or a full system with a sub for bigger events. Either way, you can grow your mobile PA setup without starting from scratch. And if you’re torn between two configurations, the Woodbrass team is on hand to point you in the right direction.
If you’re new to mobile PA, start with a pair of LUNAR 112 XA speakers: it’s the most versatile format going. Add a PORTABLE SUB whenever your gigs call for more low-end, without touching the rest of your setup.
