  • Full-Range Separable Speaker System
    The high performance speaker array consists of a pair of 4" long excursion mid/woofers and one high output tweeter per channel. The STADIUM UB4100 can also be separated into two speaker towers utilizing the optional Harman SK-300 separation kit which includes a 10’ (3m) bridge umbilical cable and rear and bottom filler plates.
  • Flexible Placement
    A versatile mounting system with universal mounting clamps, inserts, and quick release brackets offers easy installation and multi-mounting options—that includes pontoon boats!
  • Detachable Remote BT
    A detachable RF remote gives you full control over your music wherever you are without having to aim the remote at the Soundbar and worrying about the sunlight washing you out.
  • Class D Amplifier with Multi-Inputs
    The high-efficiency Class D amplifier with 80Wrms per channel is equipped with Bluetooth, 3.5mm and RCA inputs and includes intelligent priority switching, greatly simplifying the user interface by completely eliminating manual source selection. The 3.5mm jack overrides Bluetooth, which overrides the RCA inputs. Simple and efficient!
  • Party Mode
    This provides simultaneous connection of up to three Bluetooth devices—while playing music from one device at a time. Audio will stream from the device most recently selected and pause other AVRCP-compatible devices. Share playlists with three of your closest friends.
  • Outstanding Display and Appearance
    Aside from being an impressive looking product, the STADIUM UB4100 is also weatherproof with an IPx6 rating. A glowing red LED display across the front panel flashes in time with the music. And dual-level LED down lighting makes a perfect work light for reading maps or executing other on-the-move tasks.
  • Audio Output
    Two channel full-range L & R outputs enable you to expand the sound system with additional components such as a powered subwoofer or amplifier.
  • Power/Protection LED
    Power/protection LED flashes when amplifier shuts down due to overcurrent, overvolt, overtemp, or DC offset.
  • Micro USB
    A micro USB connection is provided to future proof the STADIUM UB4100 with software updates.
