| Price (US) | Not published priceUsd nulled on adversarial verification: the source (JBL official Boombox 4 English spec sheet PDF) lists no price, and the corroboration (Amazon listing, re-fetched) showed "No featured offers available" with no numeric price for the Boombox 4 itself (only unrelated accessories/similar items showed EUR prices). The $549.95 US MSRP originates from a HARMAN press release (news.harman.com, Sep 3 2025), which is NOT one of the fetched source/corroboration URLs, so it could not be confirmed verbatim here. |

Source: jbl.com.br (verified 2026-07-10) · corroborated by amazon.com. Specs verified verbatim against JBL's official Boombox 4 English spec sheet PDF (HARMAN/JBL, © 2025 HARMAN, re-fetched 2026-07-10 and extracted via pdftotext): Transducers "2 x 5 inch / 2 x 123mm woofer, 2 x 0.75 inch / 2 x 20mm Tweeter, 2 pcs circle + 1 pc racetrack passive radiator" (mapped to 2×123mm woofer + 2×20mm tweeter + 3 passive radiators); "Bluetooth version: 5.4"; "IP68 waterproof and dustproof"; "Music play time: Up to 28 hours of playtime plus 6 hours with playtime boost" (base 28 h); "Net weight: 5.89kg / 13 Ibs" (13 lb); "Connection ports: AC-in, USB-C" only (no 3.5mm aux, so aux_in=false); "effortlessly stereo pair two Boombox 4 speakers" via Auracast (stereo_pairing=true); frequency response 37Hz–20kHz. Exact model confirmed: spec sheet "Model No.: JBL Boombox 4"; Amazon corroboration lists Model Name "JBL Boombox 4" / Model Number JBLBOOMBOX4BLUAM, and independently confirms IP68, two woofers + two tweeters + three passive radiators, Auracast stereo pairing, and up to 34 h playtime (28 + 6 boost). NULLED on verification: priceUsd — neither the source spec sheet (no price) nor the Amazon corroboration ("No featured offers available", no numeric price for the item) states a price; the $549.95 figure derives from a HARMAN press release not among the fetched URLs. releaseDate and specs.release — the spec sheet shows only "© 2025" (no month) and Amazon lists no release date, so "2025-09" could not be confirmed verbatim from the fetched source/corroboration text.
