220W Peak Power IPX5 Water Resistant RGB Party Lighting
Made for Beach Days, BBQs and Outdoor Music
Take the ACEFAST K2 Max from the living room to the beach, backyard or camping setup. Its portable handle design and high-power sound make it a better fit for social moments where small speakers feel too quiet.
DSP-Enhanced Sound for a More Immersive Listen
The built-in DSP processor helps optimise audio signals for a fuller and more balanced sound experience, giving music, vocals and bass more impact during parties, movie nights and everyday listening.
Multi-Speaker System with Stronger Bass
With multiple speaker units and bass diaphragm support, the K2 Max is designed to deliver louder volume, clearer detail and stronger low-end performance than a basic compact Bluetooth speaker.
Splash-Ready for Indoor and Outdoor Use
Built for real-life use around backyards, beach days, poolside areas and outdoor gatherings. The splash-resistant design helps protect the speaker from everyday water exposure, but it should not be fully submerged.
TWS Interconnection for Bigger Stereo Sound
Pair two compatible ACEFAST speakers with TWS interconnection to create a wider stereo sound field, making movie nights, parties and larger rooms feel more immersive.
Flexible Playback for Different Setups
Play music through Bluetooth, USB flash drive or AUX input, so you are not limited to one source. It is useful for phones, laptops, tablets, offline playlists and casual home entertainment.
