Short answer: the Motion Boom, on both price and ranking. It ranks #14 of 76 large speakers at $109.99; the T9 ranks #37 at $130, $20 more.
The T9’s spec sheet reads long: 80W output, a 24-hour battery with power bank function, dual subwoofers, RGB lighting, microSD and AUX support, and even a karaoke mode with a bundled wireless microphone. Our notes still flag peaks in the upper mids that make it sound a bit harsh.
The Motion Boom keeps it simpler and measures better for it. Our notes call it excellent budget-friendly value with a genuinely long battery of its own, 24 hours claimed, and a waterproof buoyant design that doubles as a practical carry handle.
Buy the Motion Boom for the better value and higher ranking. Buy the T9 if the karaoke mode and bundled microphone specifically matter to you.
