Sony SRSULT900AC Speaker System - ULT POWER SOUND Bluetooth 148 W RMS 20 Hz to 20 kHz USB

Powerful sound and bigger bass for better parties

The prominent ULT button gives you access to two exciting bass modes. Powerful bass to feel the beat and get you dancing, or deep bass boost for low-frequency sound that will make your heart tremble.

Hit the button. Feel the bass.

Press the ULT button to enjoy the powerful sound of ULT1 and ULT2. Select ULT1 for deeper, lower frequency bass. Select ULT2 for powerful, punchy bass.

A richer, clearer, deeper experience

The non-circular diaphragm not only maximises the area of speaker diaphragm but it also increases sound pressure for deeper and punchier bass, less distortion and greater vocal clarity. Altogether, it elevates your listening experience.
