How does the OontZ Angle 3 Ultra deliver bigger bass and clear sound?

Cambridge Soundworks tuned the Angle 3 Ultra with a digital audio processor that emphasizes low-end impact while preserving midrange and high-frequency detail. The result is fuller-sounding playback from a small enclosure, with minimal distortion even at louder listening levels.

• Proprietary passive bass radiator for deeper low frequencies.
• Digital audio processing to balance bass, mids, and highs.
• Distortion-free stereo sound up to max volume.

What wireless connectivity and range can I expect?

Can I use multiple speakers together for wider stereo sound?
