The Spectrum was an indoor arena in Philadelphia, Pennsylvania. The arena opened in September 1967 as part of what is now known as the South Philadelphia Sports Complex. After several expansions of its seating capacity, it accommodated 18,168 for basketball and 17,380 for ice hockey, arena football, indoor soccer, and box lacrosse. It was the home arena for the Philadelphia Flyers and the Philadelphia 76ers from 1967 to 1996 before both moved to the CoreStates Center. The Spectrum continued to be used for concerts and as the home for other sports teams including a new AHL affiliate for the Flyers, the Philadelphia Phantoms.
