HK Audio L3 HIGH PERFORMANCE PACK - Complete sound system (2 × L3 115 FA + 2 × L Sub 1800 A)

HK Audio L3 HIGH PERFORMANCE PACK – Complete sound system (2 × L3 115 FA + 2 × L Sub 1800 A)

High-performance active PA pack designed for those who need great bass extension without sacrificing clarity in the midrange and treble. The combination of two LINEAR 3 115 FA (15”/1”) mid/tweeter units with two LINEAR SUB 1800 A (18”) subwoofers delivers a high and even sound pressure level across the entire spectrum, with an integrated DSP and 4 presets on the tops ( Bass Boost , Flat (LF) , Flat (HMF) and Contour ) to adapt the system to the room and the application in just a few steps. The set includes K&M poles with M20 thread for solid sub+top coupling and specific padded covers to protect the cabinets during transport and storage.

What's included in the pack

• 2 × HK Audio LINEAR 3 115 FA — 2-way active speaker (15” + 1” driver), 1,200 W peak, 90° × 55°, 4 DSP presets, DuoTilt 3°/7°.
• 2 × HK Audio LINEAR SUB 1800 A — 18” active bass-reflex subwoofer, 1,200 W peak, 38 Hz (−10 dB), max. peak SPL 132 dB, selectable 100/120 Hz crossover.

• Padded covers: 2 × for L3 115 FA and 2 × for L Sub 1800 A.

Main features of the system

• Great low-frequency extension: the L Sub 1800 A goes down to 38 Hz (−10 dB) providing punch and depth.
• Instant control: 4 presets on the L3 115 FA ( Bass Boost / Flat (LF) / Flat (HMF) / Contour ) to adjust the character of the system without external processors.
• Pressure and Coverage: L3 115 FA with 135 dB SPL peak (126 dB average) and 90° × 55° dispersion for consistent projection.
• Easy TOP+SUB integration: The L Sub 1800 A incorporates Mid/High outputs with high-pass and selectable crossover at 100/120 Hz for clean blending with the tops.
• Professional construction: MDF enclosures with acrylic finish, steel grille with acoustic foam and HK MultiGrip handles.
• Robust mounting: M20 masts to avoid looseness and DuoTilt 3°/7° socket on the tops to direct the beam towards the audience.

Connections and control

• L3 115 FA: 2 × XLR/Jack combo inputs (Mic/Line switchable), 1 × RCA stereo Aux input; 1 × XLR Thru; 1 × selectable XLR Thru/Mix Out; protection by limiters (peak, RMS, multiband) and subsonic filter.
• L Sub 1800 A: 2 × XLR/Jack combo inputs; 2 × XLR Thru; 2 × Mid/High Line Out with high-pass; 1,200 W peak Class D amplification, 24 dB/oct subsonic filter and limiter.

User benefits

• Quick and reliable setup: clear rear controls and direct signal flow from subs to tops.
• First-class sound in real spaces: the 15” woofer in the tops reinforces the low/midrange, and the 18” woofer in the subwoofers adds depth without losing definition.
• Protection and logistics: Custom-fit cases included for tops and subs; MultiGrip handles for secure handling.
• Scalability: possibility of expanding with more subwoofers or additional units depending on capacity.
