This is a brand new (opened the box, plugged it in to show one person, now it's back in the box and ready to go!) Bose L1 model 1S speaker system with subwoofer (B2). Bose is famous for their left to right dispersion of almost a full 180 degrees. The bass speaker is just pure deep, clean bass frequency. This system is very powerful and is perfect for audiences indoor or outdoor up to around 500 people. I really hope you buy from me. I'm a Bose dealer and this really is an awesome system for an outdoor gig. I have the L1 Compact, F1 812, and all of Bose's products available if you want to inquire about any other items. Thanks for viewing the listing and I hope to do business with you soon!
