Driven by an integrated 400-watt RMS amplification package, the system pairs two 7.5-inch woofers with dual 1-inch dome tweeters to maintain clean acoustic extension down to 40 Hz. Real-time AI Sound Boost processing actively analyses the incoming audio signal to optimise transducer excursion and prevent harmonic distortion at high sound pressure levels.\u003c\/p\u003e\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\u003cp\u003eRepresenting a substantial step forward among battery-powered portable speakers, the JBL PartyBox 520 exhibits strict acoustic control across its frequency range. The reinforced enclosure manages deep bass transients without introducing unwanted cabinet resonance or masking midrange vocal articulation. Built-in heavy-duty wheels, a telescopic handle, and an IPX4 splashproof exterior ensure practical mobility across patios, stages, and outdoor gathering spaces. With a swappable battery system supplying up to 15 hours of continuous playback, it sustains high-energy playback throughout full-length events without tethering to mains power.\u003c\/p\u003e\u003ch3\u003eKey Acoustic \u0026amp; Design Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer Support:\u003c\/strong\u003e Hi-Fi Centre is an Authorized Dealer for JBL, guaranteeing authentic products, valid manufacturer warranties, and dedicated technical service.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 7.5-Inch Woofers:\u003c\/strong\u003e High-output low-frequency drivers deliver impactful bass response down to 40 Hz with minimal compression.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAI Sound Boost:\u003c\/strong\u003e Dynamic algorithmic processing continuously monitors driver excursion and thermal thresholds to minimise acoustic distortion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwappable Battery Architecture:\u003c\/strong\u003e A field-replaceable lithium-ion battery pack provides up to 15 hours of runtime with 10-minute fast-charging capabilities.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand \u0026amp; Model:\u003c\/strong\u003e JBL PartyBox 520\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Battery-powered portable party speaker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance:\u003c\/strong\u003e Frequency response 40 Hz – 20 kHz; Signal-to-noise ratio \u0026gt; 80 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 400 W RMS (IEC60268); 100–240 V AC, 50\/60 Hz mains input; up to 15 hours playback (swappable 99.02 Wh Li-ion battery)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransducers:\u003c\/strong\u003e 2 x 7.5-inch (208 mm) woofers, 2 x 1-inch (25 mm) dome tweeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions \u0026amp; Weight:\u003c\/strong\u003e 420 x 770 x 370 mm (W x H x D); 26.0 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eI\/O \u0026amp; Connectivity:\u003c\/strong\u003e Bluetooth 5.4, Auracast multi-speaker pairing, 3.5 mm Aux input, dual 6.3 mm microphone\/guitar inputs, USB-C audio\/charge port\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":50515462684725,"sku":"PartyBox 520","price":1099.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/9355\/files\/Partybox520Angle.jpg?v=1790532244","url":"https:\/\/hificentre.com\/products\/jbl-partybox-520-portable-speaker","provider":"Hi-Fi Centre","version":"1.0","type":"link"}
