Summary: these speakers are great. Bought a brand new pair 10-12 years ago. When I decided to get another set, Bose had apparently stopped making them. the set I got off ebay is just like new, perfect sound, even had owners manual. Great for low profile applications - with high profile sound.
Summary: I bought my first pair new in 1994 and used them outside under the eve of the roof. I moved in 2006 taking the speakers with me and purchased another used pair on E-Bay to set up four around my patio. This created a great surround sound. When the house sold in 2009, the buyer was so impressed with the quality that he included the speakers in the contract to stay with the house.
Summary: Big sound , in a small package , and the range of sound , I own four of the 100's and when paired with a subwoofer, the movie experance is just that much more intence , but you don't realy need a sub because these little guys pack enuff bass , if you are limited to space and want amazing sound get your self a pair of 100s
