The best design feature of PK8 is the frame design, called the X- Grip. The 4 frames around the speakers' main body greatly enhances the product’s portability as well as its durability. Completing its profile as a speaker for the outdoors is the fact that it is fully waterproof. The front animation lighting provides users with various experiences such as high-output beat, party mode, and mood lighting. A total of six internal speakers, including two twitters that produce the clear high sound, two 2.5inch woofer units that amplify the mid and bass sound, and the dual passive radiators on both sides that produce strong bass, offer the kind of sound that will get any beach or pool party started.
