L SUB 1500 A

LINEAR SUB 1500 A is a 15” bass reflex subwoofer – a diminutive miracle of power that packs a powerful punch and offers precise playback and an impressive low end (all the way to 45 Hz). This makes this powered sub the perfect bass extension to the ELEMENTS EASY BASE, SMART BASE and LINE BASE systems, or the active 2.1 LUCAS 2K15 system.

The Speaker Stand Stretch Cover allows you to stylishly and elegantly conceal your tripod stands, allowing you to aesthetically integrate LUCAS 2K into the atmosphere of the event.

Over the course of an event, the mobile DJ must often meet a number of different audio requirements with a single PA system. As well as getting the party started and the people dancing, the PA is often used for speech applications, or to play unobtrusive background music.



When the party gets really loud and energetic, LUCAS 2K calls on its superior power reserves to deliver powerful bass at high volumes – all the while remaining perfectly balanced.



LUCAS 2K also excels as a PA whenever soft background music is required – for example at celebratory dinners – offering up a full yet pleasantly unobtrusive sound.



LUCAS 2K delivers extremely natural, transparent and easily understandable voice reproduction, making it the perfect solution for wedding speeches, celebratory toasts, or any other conceivable kind of speech application.




 LUCAS 2K15 as a 2.1-System

To achieve the best possible full-range stereo sound with a LUCAS 2K15 system, the subwoofer should be placed centrally, between the two satellites. Used this way, the satellites and subwoofer are optimally coupled in the crossover frequency range, allowing for the highest amount of usable SPL, and the sound can spread evenly throughout the entire room. The two satellites are aimed at the dancefloor, and very slightly turned inwards towards one another. The wide 90° horizontal sound dispersion angle means even the area directly in front of the DJ booth gets great sound, without any unwanted phase cancellation or reflections from walls or ceilings.


LUCAS 2K15 with an L SUB bass extension

When it comes to extending LUCAS 2K, HK Audio recommends only the relevant subwoofers from the LINEAR SUB family. This is because the L SUB basses are a perfect acoustic – and aesthetic – match for LUCAS 2K systems. In this setup, the two subwoofers are typically placed next to each other in a mono cluster, between the satellites. This results in homogenous sound dispersion in the bass and higher frequency ranges. The satellites stand to the left and right of the DJ booth, and are aimed towards the dancefloor. This is the ideal way to enjoy the most bass-rich LUCAS 2K15 sound.
