Applications
The Thunder-KS2P I is suited to permanent installations in demanding environments such as outdoor venues, marine applications, aquatic facilities, and beach bars, where IP54 ingress protection is required. It operates as a satellite subwoofer driven by a K-Array active system and can pass signal through to further passive speakers in the same installation.
Standards and compliance
IP54 ingress protection rating (dust partial protection, water splash resistance). For critical environments such as swimming pools, beaches, and yachts, K-Array recommends additional protection beyond the rated IP54 level.
