Short answer: the Infitbo D40CS. It ranks #13 of 16 soundbars with a subwoofer by sound quality, rated 3.3/5, at $98.99; the Ultimea Poseidon M60 ranks #15, rated 3.2/5, and costs $139.99, so there is not much of a tradeoff to weigh.
The case for the Infitbo D40CS: In The Hook Up’s 2026 budget shootout the D40CS took the top spot ahead of the Ultimea Poseidon M60, sounding the most dynamic of the group with clean vocals. It keeps a wired aux input, which the Ultimea Poseidon M60 lacks. Watch for: It does not play as loud as some rivals, so large rooms may need more.
What the Ultimea Poseidon M60 does well: A compact bar with a dedicated center and a small wired sub that reaches surprisingly deep with tight, controlled bass. The catch: Atmos and surround are virtual only, and the effect is barely noticeable.
Buy the Infitbo D40CS. It is rated higher for sound quality than the Ultimea Poseidon M60 and costs less, which makes it the one to get unless you need something the other one does better.
