- The HK Audio Elements MK2 takes the line array concept into a slim column, designed to cover an entire room evenly.
- The SnapLock system assembles the subwoofer, spacer, and columns with one hand, no tools or visible cables between the elements.
- Two active subwoofers, a 10 inch and a 15 inch, create the SMART BASE and BIG BASE packs, rated for up to 250 and 500 people.
- Audio and control run through a single network cable thanks to Milan-AVB, which significantly shortens setup time.
This issue is quite common for mobile DJs and bands: how to set up quickly, cleanly, without turning the venue into a technical stage? The HK Audio Elements MK2 answers this with a clear idea. A slim column, a subwoofer on the floor, and a system that grows as the room grows.
This second version of the Elements system keeps its modular spirit. It adds a revised locking system, two new subwoofers, and full network management. It remains a column system in the strict sense: you stack, you connect, you play. Let's see what each piece brings, and for what kind of gig.
The line array principle in an Elements MK2 column
A line array is a line of stacked speakers that behave as a single source. The benefit: the sound projects far and loses less level between the front row and the back of the room. It's the technique of big stages, scaled down here to a wedding or a multipurpose room.
The Elements MK2 635 column houses six 3.25-inch speakers, each paired with a phase plug waveguide. This small cone in front of the diaphragm aligns the high-frequency dispersion.
Result: a 90-degree horizontal and only 5-degree vertical dispersion. The sound spreads widely over the audience, without unnecessarily hitting the ceiling or floor. The black powder-coated aluminum cabinet weighs 7.3 kg, with an anti-corrosion treated steel grille.
This tight vertical dispersion changes the game for voice. A speech remains intelligible at the back of the room, and the front row is not overwhelmed. For a wedding with speeches and a dance floor, that's valuable.
The Spacer Elements MK2 slips between the subwoofer and the columns to place the speakers at the right height, above heads. It weighs only 3.85 kg and transmits the signal like the rest of the assembly.
SnapLock: tool-free and cable-free assembly
The new HK Audio SnapLock system mechanically connects the subwoofer, spacer, and columns in one motion. No screws, no wrench. The integrated contacts also carry the signal from one element to the next, so no cable runs along the column.
On site, you gain two things. First time, especially when setting up and tearing down multiple times a week. Then a clean installation that blends into a neat decor. The connection is said to be stable and play-free, designed to withstand repeated transport by a rental company.
The DSP automatically detects the number of connected columns and applies the appropriate midrange compensation. You add a module, the response stays balanced without touching a setting.
Two subwoofers for two uses
The subwoofers are the active core of the system: they house the amplification and DSP that also drive the passive columns. HK Audio offers two, and the choice mainly depends on what you play.
The 110 Sub A is based on a 10-inch speaker, with 900 W and 1800 W peak. It reaches 123 dB max SPL for 28.5 kg.
Its field: speech, conferences, background music, and corporate events. It offers a solid low-midrange that gives body to voices, in a size easy to load.
The 115 Sub A moves to 15 inches, with 1500 W and 3000 W peak, for 128 dB max and 39.4 kg on the scale.
It's the subwoofer for DJ sets, cover bands, and parties where the dance floor must vibrate. It brings a deeper extension in the bass and more headroom when the level rises.
Both subwoofers share the same DSP platform, controllable from the DSP Control software. It includes a 10-band parametric EQ, high-pass and low-pass filters, polarity, limiter, mute, and delay on the DSP output. Four presets cover the essentials: Flat, Contour, Voice, and Remote, the latter for custom settings.
The HK Audio Elements MK2 packs by room size
To start without calculation, HK Audio assembles two ready-to-play configurations. The stated capacities obviously depend on the music program, the venue acoustics, and the desired level.
The SMART BASE combines two 635 columns, a Spacer, and a 110 Sub A subwoofer. Thirteen speakers total, 900 W and 1800 W peak, for events up to 250 people. It's the ideal base for a wedding DJ or a speaker in a seminar room.
The BIG BASE uses the same architecture around the 115 Sub A cabinet: 1500 W and 3000 W peak, designed for up to 500 people. It's aimed at live bands and dance parties that need impact in the low end.
And the system doesn't stop there. One setup supports up to three mid-high modules and two cabinets. Adding columns mainly increases the range and consistency of coverage, rather than just volume. Handy when the same crew does a 150-seat venue on Friday and a gym on Saturday.
Start from the nature of your gigs rather than the number of guests. Lots of speech and background music: the SMART BASE is enough. Dance sets or a band with drums: the BIG BASE will give you some headroom.
Milan network and Elements MK2 system extension
The cabinets have Ethercon RJ45 connectors (a reinforced network plug for the stage). They integrate into an Ethernet and Milan-AVB network, a protocol that carries digital audio and control data on the same cable. Fewer cables to run, less chance of failure, and remote system adjustment.
The DSP Out on XLR output sends an already processed signal to other speakers: stage monitors, frontfills (small speakers covering the front rows), delay lines for the back of a long room, or additional cabinets. It also works with active speakers that are not network compatible. A classic mixer with XLR outputs is enough to power everything.
In a long room, place a pair of speakers halfway along the DSP Out output and set the delay in DSP Control. The sound from both points arrives at the ears of the audience at the back at the same time.
On the bass side, the system can be extended with the LINEAR 5 MK2 115 Sub A, which opens the door to cardioid mode setups. This cabinet placement focuses bass towards the audience and reduces it on stage, which helps musicians and microphones. Elements MK2 also coexists with the LINEAR 5 MK2 and LINEAR 9 ranges from HK Audio.
For transport, HK Audio finally announces the LS-WB1 wheeled trolley, designed for Elements MK2 cabinets as well as those from the LINEAR MK2 series. A detail that matters when unloading a van at midnight.
Who is this column system for?
The HK Audio Elements MK2 targets providers, rental companies, and event technicians. It also speaks to mobile DJs, dance or cover bands, places of worship, theaters, and cultural venues that want a discreet setup.
Its strong point can be summed up in one sentence: aesthetics matter as much as sound. At a cocktail, corporate event, or ceremony, a slim column goes unnoticed. The audience hears the music without seeing a forest of speakers.
FAQ - HK Audio Elements MK2
What is the difference between the SMART BASE and the BIG BASE?
Both packs include two 635 columns and a Spacer. The SMART BASE uses the 110 Sub A cabinet (10 inches) for events up to 250 people. The BIG BASE uses the 115 Sub A (15 inches) and targets up to 500 people.
Are the Elements MK2 635 columns active?
No, the 635 column is passive. Amplification and DSP are in the 110 Sub A and 115 Sub A cabinets, which power the columns via the SnapLock system.
How many columns can be added to the system?
An Elements MK2 setup supports up to three mid-high modules and two bass cabinets. The DSP automatically detects the number of columns and adjusts its compensation.
Is a network required to use Elements MK2?
No. XLR inputs are enough to play. The Milan-AVB network via Ethercon RJ45 adds digital audio transport and remote control on a single cable.
Can bass be added to the system?
Yes, with a second Elements MK2 cabinet or with the LINEAR 5 MK2 115 Sub A, which allows a cardioid mode setup.
With the Elements MK2, HK Audio builds a column system that adapts to the gig rather than the other way around. One column and one cabinet for Thursday's seminar, three modules and two active bass cabinets for Saturday night. Just pick your starting base and let the system grow with your dates.
