法国阿酷司l-acoustics A15 KS28 X12 K2 LA12X LA4X 娱乐音响产品

The KS28 is a reference subwoofer designed to extend the 

frequency response of large format systems. The KS28 features 

two high excursion, 18’’ direct radiating transducers mounted 

in a bass-reflex tuned enclosure. The L-Vents reduce turbulence 

and port noise at high levels while also increasing LF efficiency. 

The KS28 operates from 25 Hz. The excursion capability of 

the transducer, combined with L-Vents contributes to deliver 

a high SPL, with low distortion. The KS28 can offer standard 

or cardioid directivity, by combining physical deployment and 

the suitable preset.

The KS28 is the first L-Acoustics enclosure to fully utilize the 

LA12X amplified controller power. The LA12X ensures advan�ced crossover functions, linearization and L-Drive protection of 

the transducers. Its onboard library offers standard and cardioid 

presets, each available with two low-pass filters to accommoda�te various coupling conditions and LF contour requirements.
