Short answer: the Teufel Rockster Air, on the noted tuning problems. The Sony GTK-XB72 is credited with exceptional sound quality, powerful bass and vibrant multi-colored LED lights, yet the same notes flag no deep bass at all, a weird midrange peak, rolled-off treble and overall strange tuning. The Teufel delivers 112dB and an exceptional 58-hour battery, 31 hours at full volume in ECO mode, but its midrange is peaky and it distorts above half volume.
Buy the Teufel Rockster Air for a battery-powered PA speaker; the Sony GTK-XB72 suits a party speaker instead.

Teufel Rockster Air: €500 Discontinued eBay

Party Link Stereo pairs two units wirelessly. Measured bass extension of ~52Hz (-10dB).
