LG has just revealed that the upcoming G7 ThinQ flagship will feature a "Boombox Speaker" that packs a resonance chamber which allows it to provide 6 dB higher base sound levels and twice the amount of bass that the brand's existing flagships can deliver. The G7 ThinQ will also feature a HiFi Quad DAC and DTS:X 3D Surround Sound.
