What the Sonos Arc Ultra and Sub 4 Memorial Day deals offer
The Sonos Arc Ultra and Sonos Sub 4 Memorial Day audio deals are limited-time discounts on a premium home theater soundbar and wireless subwoofer bundle that targets buyers who want immersive Dolby Atmos sound with deep, room-shaking bass, without the complexity of a traditional AV receiver and separate speakers. The headline Sonos Arc Ultra deal sees this 9.1.4 Dolby Atmos home theater soundbar drop by USD 200 (approx. RM920) on Amazon during the holiday weekend, making a flagship-level bar more accessible. PC Guide notes that the Arc Ultra offers expansive, room-filling output, improved Atmos height effects, and AI-enhanced dialogue that helps voices stay clear over background effects and music. According to PC Guide, the Arc Ultra also supports HDMI eARC, Wi-Fi, Bluetooth, Apple AirPlay 2, and major voice assistants for both TV audio and music streaming.
Sonos Sub 4 discount: why this wireless subwoofer sale matters
Alongside the Arc Ultra, the Sonos Sub 4 discount on Amazon turns a high-end wireless subwoofer into a more tempting add-on for existing Sonos users. WePC reports that the wireless subwoofer sale brings the Sub 4 down from USD 899 (approx. RM4,135) to USD 759 (approx. RM3,490), saving buyers USD 140 (approx. RM645) for the Memorial Day period. The Sub 4 uses dual inward-facing elliptical woofers in a force-canceling design so the cabinet does not rattle or walk across the floor, even at higher volumes. Its ported enclosure and dual Class-D amplifiers deliver bass down to 25 Hz, adding the physical impact that most standalone bars cannot reach. Inside, Wi-Fi 6 radios, a faster 1.9 GHz quad-core processor, and Trueplay tuning help the sub integrate smoothly with modern Sonos soundbars and speakers.
Best-value Sonos home theater combinations this weekend
For home theater buyers, pairing the Arc Ultra with the Sub 4 creates a complete premium setup that covers both detailed surround and powerful low frequencies. The Arc Ultra’s 9.1.4-channel design handles Dolby Atmos height effects, positional audio, and dialogue clarity, while the Sub 4 focuses solely on deep, distortion-free bass. Together they form a flexible home theater soundbar system that can later be expanded with Sonos rear speakers. This combo is ideal for a main living room or media space where you want cinema-style immersion without racks of equipment. If you already own an Arc, Arc Ultra, or Beam (Gen 2), the Sub 4 deal is the obvious upgrade, since it works with most S2-compatible Sonos products and can be placed upright or flat to fit under couches or beside cabinets.
Who should grab these Memorial Day audio deals (and who can skip)
These Memorial Day audio deals are best for users ready to invest in premium, long-term home theater gear rather than entry-level soundbars. The Arc Ultra is a strong fit if you watch a lot of Dolby Atmos movies, premium TV, or cinematic games, and want a single soundbar that can fill a larger room. The Sub 4 is ideal if your current Sonos setup feels light on low-end impact, or if you want bass that you can feel as well as hear for action scenes, music, and gaming. Budget-focused buyers may prefer smaller bars or all-in-one systems, but anyone prioritizing sound quality, dialogue clarity, and upgrade paths within the Sonos ecosystem should look closely before the holiday sale ends, since both the Sonos Arc Ultra deal and the Sonos Sub 4 discount are limited-time offers.
