What customers like about LG XBOOM RNC9

  • Excellent value for money compared to premium competitors
  • Powerful 1000W output with intense double bass boost capabilities
  • Rich connectivity options including dual USB, optical, guitar, and mic inputs
  • Fun entertainment features like karaoke vocal filters, DJ pad, and app controls
  • Dynamic multi-colour RGB LED lighting that syncs to the rhythm of the music
  • Clear, distortion-free sound performance even at higher volumes

What customers don't like about LG XBOOM RNC9

  • Lacks a built-in rechargeable battery and must remain plugged into a wall outlet
  • Very large, bulky, and heavy layout making it difficult to transport without wheels
  • Bass blast mode can sometimes overpower vocal clarity and mid-tones at maximum volume
  • Noisy internal cooling fan that triggers automatically
  • Plastic-heavy exterior can feel a bit cheap to some users
  • Occasional Bluetooth connectivity drops when approaching the 30-foot range limit

Verdict

The LG XBOOM RNC9 is a high-power, floor-standing party speaker featuring a 2-way audio configuration with dual 8-inch woofers and dual 1-inch tweeters designed to deliver up to 1000W of peak audio performance. Key characteristics include a Double Super Bass Boost system, integrated multi-color rhythm-synced LED lighting, dual USB ports, an FM radio, dedicated guitar and microphone inputs, and a dedicated smartphone DJ/Karaoke application. The speaker excels with its deep, booming bass reproduction, versatile connectivity options, voice-cancelling karaoke effects, and the ability to wirelessly link with up to 10 other compatible LG speakers. However, its massive 22.5 kg footprint lacks integrated transport wheels, it requires a constant AC power grid connection due to having no built-in rechargeable battery, and it does not feature an HDMI port or Wi-Fi connectivity.
