Sonos Sub 4 Wireless Subwoofer – Save $140

Here's the description for #2: Amazon has the Sonos Sub 4 Wireless Subwoofer for $759.00 — 16% off the $899.00 list price. Rated 4.7 out of 5 stars across 481 reviews, Amazon's Choice, with 200+ bought in the past month. Available in black and white. If you already own a Sonos Arc Ultra, Arc, or Beam soundbar, the Sub 4 is the natural next step — and reviewers consistently say the difference is immediately noticeable. Dual force-canceling woofers deliver deep, clean bass with virtually no distortion or rattle, even at high volume. The ported enclosure enhances low-frequency output so you feel explosions and bass lines as much as hear them. Setup is plug-and-play: one power cable, pair through the Sonos app, done. The wireless design means you can place it anywhere in the room — upright, on its side, or tucked under a sofa — without running cables. The updated matte finish matches current Sonos hardware. The main caveat is the price. At $759 it's a significant add-on, and it's compatible only with Sonos soundbars, so this isn't a standalone purchase. But for anyone already in the Sonos ecosystem who wants genuine home theater bass, 90% of reviewers give it five stars. Free 30-day returns through Amazon.
