Used L-Acoustics K1

The L-Acoustics K1 is a 3-way full-range active WST loudspeaker enclosure built for professional live sound reinforcement and large-scale events. It is designed for environments where uniform coverage and clear sound reproduction are critical requirements, making it a common choice for sound engineers and event production companies working at touring or festival scale.

The K1 is made by L-Acoustics, a French professional audio manufacturer credited with pioneering modern line array technology. The K1 sits at the top end of the L-Acoustics touring loudspeaker range, intended for large-scale live events and touring applications where full-range active line array performance is required.

The K1 is commonly deployed with K1 SB subwoofers to extend low-frequency output, and with SB28-2 subwoofers in larger configurations. The system is driven by LA12X amplifiers housed in dedicated ampracks. Array frames and accessories designed specifically for the K1 are also used to support full system rigging and configuration.

Check that each cabinet has been tested and is in full working order, and ask whether any cosmetic work such as repainting has been carried out. Confirm the vintage of the units, as K1 cabinets span several production years. For complete system purchases, verify exactly which subwoofers, amplifiers and array frames are included. Every listing on 10K Used carries a 21-day warranty covering major functional faults; full detail is in the buying guide at 10kused.com/used-av-equipment-guide/.

Used K1 pricing varies with the age and condition of the cabinets, whether cosmetic restoration has been carried out, and the size and completeness of the package. Configurations that include matching subwoofers, LA12X ampracks and array frames command higher prices than bare cabinets alone.
