One of the best things I ever did for my home theater was to add a Klipsch powered sub to it. I love the deep, visceral bass that it delivers when I watch movies or listen to music. The Klipsch SPL-100 is part of the company's 2018 lineup, and it's a powerhouse — offering low-frequency punch way down to 27 Hz, which will make dinosaur and spaceship movies take on a whole new level of realism in your room.
A built-in, 200-watt RMS amplifier powers the 10" SPL-100 and ensures controlled, accurate bass that sounds great with movie soundtracks and music alike.
Line-level and LFE (Low-Frequency Effects) inputs let you easily connect the SPL-100 to almost any home theater or stereo receiver. Its back-panel gain, crossover, and phase controls help you fine-tune the bass to your liking, and blend its sound into your system.
