Hear the best of both music and voice with the Bose Professional AudioPack Pro S4, a background music and paging solution that brings the signature sound and quality of Bose Professional to your business, all in one convenient, ready-to-install package.

The AudioPack Pro S4 combines four FreeSpace FS2SE surface-mount loudspeakers with the FreeSpace IZA 190-HZ integrated zone amplifier, which are specifically matched to elevate your customer experience with premium audio. Each of the FreeSpace FS2SE delivers remarkably consistent tonality, clear voice reproduction, and a smooth musical response, while their pleasing aesthetic blends into any environment.

Bose Professional FS2SE Surface-Mount 2.25" 80W Passive Outdoor Loudspeaker

A passive, surface-mount, outdoor loudspeaker with a remarkably consistent tonality. The speaker features a 2.25" full-range driver with a 130 x 130° coverage pattern designed for intelligible foreground/background music and paging applications in retail stores, restaurants, resorts, and more.

The FS2SE handles up to 80W of peak handling power and is capable of producing a maximum peak SPL of 106 dB. The integrated multi-tap transformer can be configured for an array of 70/100V settings via a convenient thumbwheel beneath the grille. The FS2SE is voiced to ensure consistent tonality throughout the FreeSpace family, so it can be installed alongside other surface-mount and in-ceiling loudspeakers without compromising the system's sonic signature. The supplied U-brackets allows horizontal or vertical orientation and adjustable pitch or yaw. A removeable logo and weather-resistant input cover are also included.

Bose Professional Freespace IZA 190-Hz Integrated Zone Amplifier (70/100V)

An easy-to-use background/foreground music and paging integrated zone amplifier that's well suited for retail stores, restaurants, bars, hospitality venues, conference centers, schools, and auxiliary zones. The IZA 190-HZ delivers premium sound, provides a simplified setup, and easy daily operation and offers the flexibility to expand when additional loudspeakers are required. The IZA 190-HZ features signal processing, routing, paging, and amplification on a single 90W Euroblock speaker output with separate leads for 70 and 100V. The unit offers a variety of easy-to-use input connections (mic/line/page), input gain and output level adjustments, and operational modes. When used with FreeSpace FS2 and FS4 loudspeakers, even further sound optimization is possible through onboard selectable EQ presets.
