Samsung MX-ST90B Sound Tower Portable Party Speaker - 1700W Power

In this review the Samsung MX-ST90B Sound Tower is assessed as a portable party speaker for people who want room-filling low end and feature-rich party controls. The bottom line: this is for hosts and outdoor entertainers who want a physically large, high-power unit that emphasizes strong bass and LED-driven party atmosphere. It stands out because its bi-directional sound and 1700W output deliver an immersive, floor-shaking experience that works for backyard gatherings, tailgates, and larger indoor rooms.

Key Features

• Bi-directional sound: Dual-facing speakers push sound across a room so listeners feel bass and presence from multiple angles during parties.
• 1700W high power: The rated power gives plenty of volume headroom for large spaces and keeps playback clear at high levels.
• IPX5 water resistant: The cabinet is protected against low-pressure water jets so it can handle splashes at pool parties or light rain.
• Party Lights+: Built-in LED modes including party, ambient, and dance let you set mood lighting without extra accessories.
• Karaoke mode: Two mic inputs enable singing with a friend and basic live vocal fun for social gatherings.
• Bluetooth multi-connection: Pair two devices at once to share control and queue music without constantly switching phones.

Who It's For

The MX-ST90B is aimed at hosts who prioritize loud, physical sound and integrated party features over compactness. It suits people who move gear between backyard, garage, or park thanks to the included wheels and who want simple on-device lighting and karaoke options.

It is less suitable for buyers who need a discreet bookshelf speaker or a battery-powered boombox for long off-grid use. Also, listeners wanting studio-grade neutrality should look elsewhere, since this design favors impactful party bass and presentation.

• Versatile party features including Party Lights+, karaoke inputs, and multi-device Bluetooth.

Cons

Our Verdict
