Engineered to deliver 1,100 watts RMS across a three-way, six-driver acoustic layout, the JBL PartyBox Ultimate incorporates dual 242 mm subwoofers, two 120 mm midrange drivers, and dual 74 mm tweeters capable of low-frequency extension down to 30 Hz. Dual microphone inputs, dedicated guitar connectivity, multi-dimensional dynamic lighting, and an IPX4 splashproof chassis complete the standalone enclosure.\u003c\/p\u003e\u003ch3\u003eThe Hi-Fi Centre Team Take\u003c\/h3\u003e\u003cp\u003eCompared to conventional portable speakers, the JBL PartyBox Ultimate demonstrates an unexpectedly composed acoustic profile, delivering substantial low-end displacement without collapsing into distortion or high-frequency harshness at elevated listening levels. The integration of dual-band Wi-Fi streaming alongside standard Bluetooth transmission enables native high-resolution playback and Dolby Atmos spatial decoding, generating an expansive, layered soundstage across large indoor spaces or open-air patios. At nearly 40 kilograms, this mains-tethered loudspeaker requires deliberate physical placement, though heavy-duty wheels and an integrated handle facilitate straightforward repositioning across flat surfaces. The resulting presentation remains authoritative and room-energising, maintaining clear instrumental separation as effortlessly as the JBL PartyBox Ultimate handles continuous sub-bass demands.\u003c\/p\u003e\u003ch3\u003eKey Acoustic \u0026amp; Design Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSix-Driver Acoustic Array:\u003c\/strong\u003e Dual 9-inch subwoofers, dual 4.5-inch midrange units, and dual 2.75-inch tweeters generate 1,100 watts RMS of dynamic sound down to 30 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Resolution Wireless Streaming:\u003c\/strong\u003e Dual-band Wi-Fi 6 and Bluetooth 5.3 architecture facilitate lossless audio and immersive Dolby Atmos spatial playback without interruption from phone notifications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSplashproof Event Enclosure:\u003c\/strong\u003e Heavy-duty rolling wheels, a solid transport handle, and IPX4 splash resistance provide physical resilience for indoor and outdoor environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorized Dealer Support:\u003c\/strong\u003e Hi-Fi Centre is an Authorized Dealer, ensuring genuine manufacturer warranty coverage, certified product provenance, and specialist technical support.\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 Ultimate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker Type:\u003c\/strong\u003e Mains-powered three-way party loudspeaker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAcoustic Performance:\u003c\/strong\u003e Frequency response 30 Hz – 20,000 Hz (-6 dB), signal-to-noise ratio \u0026gt; 80 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Output:\u003c\/strong\u003e 1,100 W RMS (IEC60268)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDriver Complement:\u003c\/strong\u003e 2 x 242 mm (9 in) subwoofers, 2 x 120 mm (4.5 in) midrange drivers, 2 x 74 mm (2.75 in) tweeters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWireless Connectivity:\u003c\/strong\u003e Wi-Fi 6 (802.11 a\/b\/g\/n\/ac\/ax, 2.4 GHz \/ 5 GHz), Bluetooth 5.3 (A2DP V1.3, AVRCP V1.5)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs \u0026amp; Outputs:\u003c\/strong\u003e 1 x 3.5 mm auxiliary input, 2 x 6.35 mm microphone inputs (one shared with instrument), 1 x 3.5 mm daisy-chain input\/output, 1 x USB-A port (5 V \/ 2.1 A charge out \/ audio playback)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W x H x D):\u003c\/strong\u003e 455 mm x 1,049 mm x 440 mm (17.9 in x 41.3 in x 17.3 in)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 39.5 kg (87.1 lbs)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress Protection:\u003c\/strong\u003e IPX4 splashproof\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JBL","offers":[{"title":"Default Title","offer_id":50515469500469,"sku":"PartyBox Ultimate","price":2499.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2246\/9355\/files\/PartyboxUltimate.jpg?v=1790532586","url":"https:\/\/hificentre.com\/products\/jbl-partybox-ultimate-portable-speaker","provider":"Hi-Fi Centre","version":"1.0","type":"link"}
