With a maximum SPL of 130dB, bass response extending down to 35Hz and an integrated 4-channel mixer, the POLAR 15 MK2 is built to handle everything from mobile DJ sets and wedding receptions to live music and corporate events.

Powerful 15-Inch Bass for DJs and Live Events

At the heart of the POLAR 15 MK2 is a high-performance 15-inch woofer housed in a generously sized plywood subwoofer enclosure. Designed to deliver powerful, controlled low frequencies, the system reaches down to 35Hz, giving kick drums, basslines and electronic music the depth and impact they need.

The rigid wooden cabinet helps minimise unwanted resonance, keeping bass reproduction tight and defined even during demanding performances. Whether you're playing dance music at a wedding, entertaining a packed dancefloor or performing with a live band, the POLAR 15 MK2 provides a substantial low-frequency foundation.

Clear Sound with Wide Audience Coverage

The column speaker features six efficient 3-inch neodymium midrange drivers housed in a rigid, low-resonance aluminium profile. A dedicated 1-inch precision tweeter works alongside a Constant Directivity horn to deliver detailed high frequencies and clear vocal reproduction.

With 120° horizontal and 30° vertical dispersion, the POLAR 15 MK2 provides broad, controlled sound coverage. This makes it particularly useful for mobile DJs, wedding venues, function rooms and live performances where consistent sound across the audience is essential.

The redesigned column connection system also makes assembly straightforward, with secure connections between the subwoofer, spacer and mid/high unit.

Integrated 4-Channel Mixer

The built-in 4-channel mixer gives you the flexibility to connect multiple audio sources directly to the PA system, reducing the need to carry a separate mixer for simpler setups.

Two microphone/line channels feature XLR/jack combination inputs with individual gain controls, making them suitable for microphones, keyboards and external mixers. Switchable phantom power supports compatible condenser microphones, while a dedicated high-impedance instrument input accommodates instruments such as electric or acoustic-electric guitars.

A stereo auxiliary input provides connectivity for DJ equipment and music players, with Bluetooth audio playback also controlled through the mixer. An XLR mix output allows further integration into larger sound systems.

Bluetooth 5.0 with True Wireless Stereo

Built-in Bluetooth 5.0 makes it easy to stream music wirelessly from a compatible smartphone or tablet. It's a convenient option for background music, event playlists, breaks between performances and general music playback.

For larger setups, Bluetooth True Wireless Stereo (TWS) allows two compatible POLAR MK2 systems to be paired wirelessly for stereo Bluetooth playback. This provides a straightforward way to expand your sound system while maintaining a clean setup.

Professional DSP with Music, Voice and DJ Modes

The POLAR 15 MK2 features integrated digital signal processing, allowing you to tailor the system's sound to different applications and venues.

Three selectable sound modes, Music, Voice and DJ, provide convenient starting points for different types of performance. A 3-band master EQ with semi-parametric midrange adjustment offers additional control, while five user presets allow you to save and recall your preferred settings.

The DSP also includes a system delay function, useful when integrating the POLAR 15 MK2 into larger PA configurations. Settings are accessed through the built-in LCD display and Push-to-Edit control.

M20 FlexMount for a Cleaner DJ Setup

One of the standout additions to the POLAR 15 MK2 is the integrated M20 FlexMount thread in the subwoofer cabinet.

This allows a compatible threaded mounting pole to be fitted directly to the subwoofer, providing a convenient mounting point for suitable lighting fixtures and show accessories. For mobile DJs and event professionals, it can reduce the number of separate stands required, helping create a tidier setup while saving valuable floor space.

It's a particularly practical feature for wedding DJs, mobile entertainers and anyone regularly transporting both sound and lighting equipment between venues.

Easy Transport and Quick Assembly

Despite its powerful output and substantial 15-inch subwoofer, the POLAR 15 MK2 has been designed with regular transport and setup in mind.

HK Audio's MultiGrip handles and additional recessed grips make the subwoofer easier to lift and position, while the modular column design allows the system to be assembled without complicated cabling or separate speaker stands.

A padded protective cover for the subwoofer and a dedicated carry bag for the column components are included as standard. An optional POLAR 15 MK2 wheel board is also available for easier movement between vehicles and venues.

USB-C Charging for Your Equipment

A built-in USB-C charging port provides a convenient power source for compatible smartphones, tablets and rechargeable wireless microphone receivers.

With a 5V/0.9A charging output, it helps keep essential devices powered during performances without requiring an additional USB charger.

Expandable for Larger Events

A single POLAR 15 MK2 provides a complete column PA solution, but the system can also grow alongside your requirements.

Using two systems creates a wider stereo PA configuration, while additional low-frequency reinforcement can be achieved with compatible HK Audio PORTABLE SUB 115 A or PORTABLE SUB 118 A active subwoofers.

This flexibility makes the POLAR 15 MK2 a practical investment for DJs and performers working across venues of different sizes.
