NHT C Series C-3 3-Way Bookshelf Speaker (Single) - High Gloss Black With excellent dispersion and detail typically found only in the most expensive designs, the C-3's bookshelf design provides a wide soundstage for its size. Compact bookshelf cabinet construction houses a high-efficiency 6.5-inch aluminum cone woofer, 2-inch aluminum dome midrange, and 1-inch aluminum dome tweeter. Bass response down to 40Hz makes subwoofers optional. Combine with other NHT C-Series components for an audiophile grade system for home theater. Improving on earlier NHT designs, the C-3 is sturdier and more serviceable.
