Bose Professional FreeSpace FS4SE 50W 2-Way Surface-Mount Speaker - White

Background music and paging in outdoor or challenging indoor spaces often suffer from weak bass, harsh highs, or weather damage. The Bose Professional FreeSpace FS4SE solves this with a 4.5-inch woofer and 0.75-inch dome tweeter in a durable, IP55-rated enclosure, delivering clear, full-range sound from a compact surface-mount speaker.

Who is it for

Installers and business owners who need reliable, high-quality audio in restaurants, retail stores, hospitality venues, or outdoor patios. The FS4SE is ideal for background music, announcements, and small-to-medium sound reinforcement where consistent coverage and weather resistance are required.
