Have more fun with Party Playlist and Karaoke Ranking through our Fiestable app. Protectors make the unit hardwearing and castors make transportation easier than ever. With Spread Sound, two High-efficiency Tweeters and Midrange will spread your music wider and higher from the front of the unit, so all of your guests will enjoy a rich, clear sound. The two High-efficiency Tweeters that use horn tweeters on the front of the MHC-V43D expand the sound stage and increase sound pressure level upward, so your music travels further, wider and higher. High-efficiency Midrange that uses mid horn speakers on the front and back distributes sound with improved clarity and sound pressure for the vital midrange frequencies. This means that whether youre in front of the unit or behind, close up or far away, you can enjoy clearer vocals as you dance or sing along to your favourite tracks. A tapered bass reflex duct structure concentrates the airflow of the bass sound, so you can hear it clearly and feel it physically, wherever you are in the crowd and over long distances. DSP Technology creates that festival vibe by giving your music the realistic ambience of a music festival and live concert.
