The Klipsch R-121SW is a 12-inch Reference subwoofer built around a high-excursion spun-copper TCP (thermoformed crystalline polymer) woofer and a built-in all-digital amplifier delivering 200 watts continuous and 400 watts peak. Its front-firing driver provides deep bass with flexible room placement.
Why This Model Matters
The R-121SW represents the latest generation of the legendary Klipsch Reference line, pairing revamped TCP woofers with an efficient all-digital amp for cleaner, deeper bass and reduced cone breakup. Reinforced 3/4-inch MDF construction and updated bracing keep the cabinet quiet so you hear the music, not the box.
