HK Audio GALA SUB 15 is a professional subwoofer model optimally designed for medium and large scale performance sound systems, especially compatible with the HK Audio ELEMENTS GALA speaker line.

With a sturdy design, powerful bass and flexible connections, the product delivers impressive audio performance, meeting the rigorous demands of live music performances, stages, halls and outdoor events.

Introducing the HK Audio GALA SUB 15 Subwoofer

HK Audio GALA SUB 15 is a professional 15-inch subwoofer, designed specifically for performance and stage sound systems. With a peak SPL of up to 129 dB, a frequency range of 44 Hz - 130 Hz and a powerful 15-inch bass driver, the product delivers deep, solid and powerful bass.

Technical parameters of the product to consider:

• Speaker Type – Professional 15 inch Subwoofer Specializes in reproducing bass frequencies from 44 Hz and above. The large diameter of the woofer increases the diaphragm area, allowing more air to move, thereby reproducing deep, thick and powerful bass - especially suitable for live music, DJs and stage performances.
• SPL (Sound Pressure Level): Peak 129 dB is a parameter that shows the maximum volume level that the speaker can emit in halfspace conditions (usually when placed close to the ground). 10% THD (Total Harmonic Distortion) is the level of sound distortion at maximum power.
• Frequency range 44 Hz – 130 Hz is the optimal operating area for the subwoofer, helping to create a solid bass foundation for the entire sound system.
• Filter slope 24 dB/oct (Linkwitz-Riley crossover) allows precise frequency division and reduces sound overlap with mid/high speakers, resulting in clear, balanced sound.
• Error ±5 dB represents the speaker's linearity, showing that the GALA SUB 15 maintains volume uniformity throughout the entire operating frequency range.
• LF Speaker – 1x 15″ is a bass reproduction component, with a size of 15 inches ideal for high-power subwoofers. The speaker membrane can be made of synthetic fiber paper (treated cellulose) combined with a large-sized voice coil and corrugated ribs, withstand high power and operate durably for a long time.
• Input – 2x XLR/6.35 mm combo: The combo jack input supports both balanced XLR and 6.35mm TRS, compatible with mixers, digital echo, microphones or other signal processing devices. This design makes the system flexible and easy to connect whether using professional or semi-professional equipment.
• Output – 2x XLR Thru, 2x Speakon Mid/High Out: The XLR Thru port allows the signal to be transmitted to another speaker, supporting the construction of a daisy-chain multi-speaker system. The Speakon Mid/High Out port is the power output port for satellite speakers (mid/high), often used to match with top speakers in the HK Audio ELEMENTS GALA system.
• Grips – 2x MultiGrip is HK Audio's specialized handle technology, with an ergonomic design, making it easy to lift, carry or transport equipment in many positions. Suitable for stage technical teams that frequently move or install mobile.
• Case – MDF is a popular material in the manufacture of high-end speaker cabinets, capable of reducing vibration and preventing unwanted resonance. Combined with a closed cabinet structure and internal bracing, the speaker achieves high solidity and acoustic stability.
• Protective mesh – Metal + acoustic foam has the effect of preventing impact and protecting the speaker membrane. The sound-absorbing foam layer at the back helps reduce dust while maintaining optimal acoustic properties, limiting unwanted sound reflections.
• Dimensions – 48 x 48.5 x 59.5 cm: This size allows the speaker to optimize the resonance volume in the cabinet, while remaining compact enough to be moved or installed in a standard stage space.
• Weight – 30.2 kg / 66.6 lbs: This mass balances performance and portability, allowing one person to operate the speaker with a dedicated cart or bag.
• Optional accessories – GALA SUB 15 Roller Bag: The Roller Bag is the ideal solution for touring bands, DJs or event organizers who need to transport multiple subwoofers. The padded, heavy-duty design helps protect your equipment from bumps and dust during transport.

Outstanding features of HK Audio GALA SUB 15 Subwoofer

HK Audio GALA SUB 15  is a line of subwoofers made for professional audio workers – where stability, convenience and performance are just as important as volume or frequency range.

Below are the outstanding features that make up the true value of the HK Audio GALA SUB 15 speaker - factors you can only feel when actually using it.

• Optimized design for professional performance systems: HK Audio GALA SUB 15 is not just a single subwoofer, but is designed to integrate perfectly with the ELEMENTS GALA system. This helps users easily expand the sound system in a modular way without having to adjust too much about the combination.
• High flexibility in installation configuration: HK Audio GALA SUB 15 speakers can be used in many different spaces such as conference rooms, mobile stages, outdoor events, tea rooms, bars... without having to change too much in the layout. This is thanks to the ability to accurately divide frequencies and diverse output signals for satellite speakers (mid/high out).
• Easy to transport and install: With its clever MultiGrip handle and optional Roller Bag, the GALA SUB 15 is extremely convenient for technical teams that move around frequently. This is a big plus for event organizers, touring bands, or flexible DJ setups.
• High stability and durability in harsh operating environments: HK Audio has invested in the cabinet structure and protective materials to ensure the speaker operates stably even when used continuously in humid, dusty or changing ambient temperatures. This brings high reliability, minimizing the risk of problems during performance.
• Clean, deep and easy-to-match bass: Unlike many subwoofer models that produce bass that is too "heavy" causing background hum or overpowering the mid-range, the GALA SUB 15 delivers accurate, well-controlled bass, suitable for pairing with full-range speakers, line arrays or professional karaoke systems. Users can easily process post-production sound thanks to the fidelity of the bass signal emitted.
• Synchronized product ecosystem from HK Audio: When using HK Audio GALA SUB 15 with other products in HK Audio's ELEMENTS or LINEAR ecosystem, users will enjoy absolute compatibility in phase, sensitivity and crossover frequency - something that many asynchronous brands often find difficult to achieve.

Detailed review of HK Audio GALA SUB 15 Speaker

Overall design – Durable, sturdy

HK Audio GALA SUB 15 speaker has a professional and sturdy design, meeting the maximum requirements of aesthetics as well as durability in the stage environment.

The cabinet is made of MDF (Medium-Density Fiberboard) which is resistant to vibration and unwanted sound resonance, ensuring stable sound quality.

The outer coating is Black acrylic enamel, which not only increases aesthetics but also helps protect the speaker box from impacts during transportation. In addition, the MultiGrip handle design on both sides makes it easy for users to carry or install in different stage spaces.

The overall appearance of the GALA SUB 15 exudes professionalism, solidity and is suitable for all performance spaces, from closed halls to outdoor stages.

Bass Quality – Powerful, Accurate and Deep

HK Audio GALA SUB 15 impresses with powerful, clean and deep bass, reproduced through a dedicated 15-inch bass driver (1x 15″ LF Speaker).

With a peak SPL of up to 129 dB @10% THD (Halfspace), the speaker is capable of generating extremely high sound pressure while still controlling distortion well. This allows the GALA SUB 15 to operate effectively in large spaces without the need for additional support equipment.

The frequency response range from 44 Hz to 130 Hz, along with a crossover slope of 24 dB/oct, helps the speaker focus on accurately reproducing the bass range without overwhelming the mid or treble range, bringing a harmonious and balanced sound quality. In particular, the bass from the HK Audio GALA SUB 15 15 Speaker is not boomy, not diluted but very "solid", creating a solid foundation for the entire performance sound system.

Connectivity and Integration – Flexible, Easy to Mix and Match

HK Audio GALA SUB 15 is equipped with a full and diverse connection port system, suitable for both professional and semi-professional environments. Two combo input ports (XLR/6.35mm TRS) help users easily connect to mixers, digital echo, or signal processors from many different sources.

In addition, the speaker also has two XLR Thru ports to daisy-chain signals to other speakers in the system without signal loss. In particular, two Speakon Mid/High Out ports allow users to output power signals to satellite speakers (mid/high), creating a complete matching system.

This design clearly demonstrates the optimization for small line array configurations, mobile sound systems or medium to large stage systems, especially compatible with the HK Audio ELEMENTS GALA series and other audio equipment on the market.

Portability – Optimized for installation and movement

Despite owning a 15-inch speaker with high power, HK Audio GALA SUB 15 still maintains high mobility thanks to its weight of only 30.2 kg, and relatively compact size of 48 x 48.5 x 59.5 cm. Users can easily arrange the speaker in a transport vehicle or install it quickly without too much manpower.

In particular, HK Audio provides additional specialized ROLLER BAG accessories to help protect the speakers during transportation and support easy pushing and pulling. This is a great advantage for event organizers, touring bands or sound rental companies that often have to transport equipment across many locations.

The dual-sided MultiGrip handle design also contributes to improved maneuverability in tight spaces or quick set-up times.
