Built on an updated hardware platform, the Sub 4 features refreshed internal processing power, expanded memory, upgraded Wi-Fi 6 wireless radios, and an updated matte-finish enclosure that aligns visually with modern Sonos soundbars and ambient speakers.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"2\"\u003eAcoustic Architecture and Force-Cancelling Engineering\u003c\/h3\u003e\n\u003cp data-path-to-node=\"3\"\u003eThe core acoustic structure of the \u003cb data-index-in-node=\"35\" data-path-to-node=\"3\"\u003eSub 4\u003c\/b\u003e utilizes dual \u003cb data-index-in-node=\"55\" data-path-to-node=\"3\"\u003e5x8-inch elliptical woofers\u003c\/b\u003e mounted face-to-face inside a precision-engineered ported enclosure. Powered by dual Class-D digital amplifiers, these inward-firing drivers create a natural \u003cb data-index-in-node=\"241\" data-path-to-node=\"3\"\u003eforce-cancelling effect\u003c\/b\u003e that neutralises mechanical cabinet vibration and eliminates distortion. This enables the subwoofer to reproduce clean low frequencies down to \u003cb data-index-in-node=\"408\" data-path-to-node=\"3\"\u003e25 Hz\u003c\/b\u003e without mechanical buzz, cabinet rattling, or unwanted resonance.\u003c\/p\u003e\n\u003cp data-path-to-node=\"4\"\u003eBy pairing the Sub 4 with an active home theatre setup, the host soundbar automatically delegates low-frequency playback to the subwoofer. This frees up the mid-range and high-frequency drivers in the main soundbar or satellite speakers, improving clarity, dynamic range, and spatial soundstage separation across movies and music.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eSystem Tuning, Dual-Sub Configurations, and Placement\u003c\/h3\u003e\n\u003cp data-path-to-node=\"6\"\u003eThe Sub 4 integrates with \u003cb data-index-in-node=\"26\" data-path-to-node=\"6\"\u003eSonos Trueplay\u003c\/b\u003e room calibration software, using mobile measurement microphones to measure room boundaries and automatically balance frequency response to suit local room acoustics. Manual bass, treble, and loudness controls remain accessible within the Sonos app interface.\u003c\/p\u003e\n\u003cp data-path-to-node=\"7\"\u003eFor large open-plan living spaces or dedicated home theatre installations, the system supports \u003cb data-index-in-node=\"95\" data-path-to-node=\"7\"\u003edual-subwoofer setups\u003c\/b\u003e. A pair of Sub 4 units can be bound to flagship soundbars like the Sonos Arc or Arc Ultra, increasing total low-end output, smoothing out acoustic room nodes, and delivering even bass coverage across multiple seating positions. The enclosure supports versatile physical placement, operating either standing upright on its integrated rubber feet or laid flat on its side to tuck beneath low-profile furniture.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"8\"\u003eTechnical Specification Overview\u003c\/h3\u003e\n\u003ctable
