Elevate your home audio experience with the Bose Acoustimass 15 Series II 6.1 Upgrade with Rear Center Speaker. This sleek and stylish white subwoofer is designed to complement your existing sound system seamlessly. With 200W RMS power and wired connectivity, you can enjoy crystal clear, powerful sound for your favorite music, movies, and TV shows. The Bose Acoustimass is the perfect addition to your home speakers and subwoofers collection. Its superior brand quality, reliable model, and exceptional color make it a must-have for any audiophile. With this upgrade kit center speaker, you can transform your entertainment area into a cinematic experience. Functionally is equivalent to Acoustimass 16 system. When originally purchased from Bose Store, was a factory renewed product. Comes with all RCA plug wiring for 6 speakers, extra speaker cable with RCA plug included, Original Owners Guide, wall/ceiling brackets for 5 speakers (instructions included but no anchors), as well as a module input cable adapter (pigtail) for use with your existing wiring or bare end cabling. I used the pigtail and wall mounts. Two or three speaker wire input thumb releases might stick. Commonplace on Bose cubes (see internet discussion). If so, just release the thumb press with a small flat-blade screwdriver and all is well. Very easy to do! Will need a 6.1 or 7.1 or greater receiver to power all 6 speakers. Can run 5.1 receiver with 5 speakers not 6. Please see photos and feel free to contact me with any questions.
