Production Timeline & BackgroundThe SF-1 towers were manufactured at the Klipsch factory in Hope, Arkansas and were actively produced from 1999 until they were discontinued in late 2004. They originally launched at a retail price of approximately $500 per pair. [1, 2, 3, 4]Overview & PerformanceThe SF-1 is highly regarded for its extreme efficiency, allowing it to deliver massive, dynamic sound even when powered by modest or entry-level home theater receivers. Because of the signature horn-loaded tweeter technology, they excel at reproducing clear, bright highs and crisp vocals. [1, 2, 3]System Setup Tips

• Placement: Because these towers feature a large rear-firing flared bass port, try to leave at least 1–2 feet of clearance between the back of the cabinet and the wall behind them to avoid boomy or loose bass. [1, 2]
• Crossover Setting: If you are pairing these with a separate powered subwoofer, home audio forums on Audioholics and the Klipsch Community generally recommend setting your AV receiver's crossover frequency between 60Hz and 80Hz. This allows a subwoofer to handle the ultra-deep low end while letting the 6.5" woofers sing cleanly in their ideal comfort zone. [1, 2, 3, 4, 5]
