Overview
The Bobtot K89 is a 2.0-channel system rated at 1400 watts, connecting via Bluetooth, optical, or USB. At nearly 19 inches wide and over 20 lb, it is built as a substantial standalone unit rather than a slim soundbar.
A 1400W rating on a 2.0-channel system is a large figure for just two channels, so it likely reflects a combined or peak power spec rather than continuous RMS per channel, worth checking before comparing it to smaller-wattage bars. Three connection options give it more flexibility than remote-only units for pairing with a TV, phone, or computer. Its size and weight point to floor or shelf placement rather than wall mounting, since no mounting spec is listed.
- 2.0-channel, 1400W rated
- Bluetooth, optical, and USB
- 18.89 x 10.62 x 17.32 in
- 20.2 lb
Who it's for
Fits someone wanting a loud, multi-input 2.0 system for a living room or gathering space rather than a discreet under-TV bar. Less suited to anyone tight on shelf space or wanting a wall-mounted profile.
Pros and cons
- Multiple inputs: Bluetooth, optical, and USB
- High-wattage rating for loud output
- Substantial build at over 20 lb
- Only 2.0 channels, no dedicated surround speakers
- Large footprint compared to slim soundbars
- No wall-mount option listed
Performance notes
With optical and USB alongside Bluetooth, the K89 can take a digital audio feed from a TV's optical port as well as wireless or wired sources, giving it broader compatibility than Bluetooth-only speakers. Its 20+ lb weight and cabinet-style dimensions point to internal drivers built for volume over a compact footprint.
