Canton"s Chrono 507 DC is a 2-1/2-way floorstanding speaker. Able to handle up to 170 watts, each silver high gloss enclosure houses a 7-inch aluminum wave surround woofer, a 7-inch aluminum wave surround midrange driver, and a 1-inch aluminum-manganese tweeter. The Chrono 507 DC features DC technology, which allows the speaker to provide sharp, precise bass reproduction at much lower frequencies than can be attained with conventional crossover designs.
