Each pack pairs four black surface-mount loudspeakers with a factory-matched integrated zone amplifier, delivering even background music and clear paging coverage straight out of the box, with no complicated component matching or guesswork required.\u003c\/p\u003e\n\u003cp\u003eAt the heart of the system are four FreeSpace FS2SE surface-mount loudspeakers, each built around a full-range 2.25-inch driver tuned for natural, intelligible voice reproduction and rich background music. Their wide 145 x 140 degree nominal coverage means fewer speakers are needed for consistent, room-filling sound, while weather-resistant IP55-rated enclosures made from UV fade-resistant engineered plastic make them equally suited to indoor walls or covered outdoor patios. Combined 70V\/100V and 16-ohm low-impedance operation gives installers maximum flexibility across zones and venues.\u003c\/p\u003e\n\u003cp\u003eDriving the loudspeakers is the FreeSpace IZA 190-HZ integrated zone amplifier, which combines signal processing, source routing, paging, and 90 watts of amplification in a compact half-rack chassis. With included U-bracket mounts for flexible aiming, removable Bose Professional logos for a clean, branded-or-discreet look, and QR-code-guided setup, the AudioPack Pro S4B is engineered for fast, professional installation and dependable, long-term commercial performance.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComplete, ready-to-install commercial background music and paging system\u003c\/li\u003e\n\u003cli\u003eFour (4) black FreeSpace FS2SE surface-mount loudspeakers, factory-matched to the included amplifier\u003c\/li\u003e\n\u003cli\u003eFreeSpace IZA 190-HZ integrated zone amplifier with signal processing, routing, paging, and 90W output\u003c\/li\u003e\n\u003cli\u003eFull-range 2.25-inch driver delivers clear voice and music reproduction\u003c\/li\u003e\n\u003cli\u003eWide 145 x 140 degree nominal coverage for even, room-filling sound from fewer speakers\u003c\/li\u003e\n\u003cli\u003eWeather-resistant IP55-rated loudspeakers for indoor or covered-outdoor installations\u003c\/li\u003e\n\u003cli\u003eCombined 70V\/100V and 16-ohm low-impedance operation for installation flexibility\u003c\/li\u003e\n\u003cli\u003eUV fade-resistant engineered-plastic enclosures with removable Bose Professional logos\u003c\/li\u003e\n\u003cli\u003eAdjustable U-bracket mounts allow horizontal or vertical orientation with pitch and yaw aiming\u003c\/li\u003e\n\u003cli\u003eQR-code-guided installation for fast, professional setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem:\u003c\/strong\u003e 4 x FreeSpace FS2SE loudspeakers + 1 x FreeSpace IZA 190-HZ amplifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoudspeaker driver:\u003c\/strong\u003e 1 x 2.25 in (57 mm) full-range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response (-10 dB):\u003c\/strong\u003e 83 Hz - 19 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 87 dB (SPL\/1W @ 1m)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum SPL:\u003c\/strong\u003e 99 dB @ 1 m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower handling:\u003c\/strong\u003e 16 W continuous \/ 64 W peak\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal impedance:\u003c\/strong\u003e 16 ohms (transformer bypass)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal coverage:\u003c\/strong\u003e 145 deg horizontal x 140 deg vertical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e70V transformer taps:\u003c\/strong\u003e 1, 2, 4, 8, 16 W (plus bypass)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100V transformer taps:\u003c\/strong\u003e 2, 4, 8, 16 W (plus bypass)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIngress protection:\u003c\/strong\u003e IP55 (loudspeakers)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoudspeaker dimensions:\u003c\/strong\u003e 7.1 x 4.4 x 4.5 in (H x W x D)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoudspeaker weight:\u003c\/strong\u003e 3.2 lb each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier output:\u003c\/strong\u003e 90 W (70V \/ 100V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmplifier format:\u003c\/strong\u003e 1U high, half-rack wide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains voltage:\u003c\/strong\u003e 100-240 VAC, 50\/60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 5 years\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e4 x FreeSpace FS2SE surface-mount loudspeakers (black)\u003c\/li\u003e\n\u003cli\u003e1 x FreeSpace IZA 190-HZ integrated zone amplifier\u003c\/li\u003e\n\u003cli\u003eU-bracket mounts for the loudspeakers\u003c\/li\u003e\n\u003cli\u003eWeather-resistant input covers\u003c\/li\u003e\n\u003cli\u003eRemovable Bose Professional logos\u003c\/li\u003e\n\u003cli\u003eQR-code installation guide \/ documentation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bose Professional","offers":[{"title":"Default Title","offer_id":46468580245701,"sku":"BOSE-AUDIOPACKPROS4B-8884781110","price":999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/BoseProfessional-AudioPackProS4B-CommercialA.png?v=1782756438","url":"https:\/\/avlgear.com\/products\/bose-professional-audiopack-pro-s4b-surface-mount-loudspeaker-system-black","provider":"AVLGEAR","version":"1.0","type":"link"}
