Canton"s Ergo 690 DC is a three-way floorstanding speaker. Able to handle up to 320 watts, each ash-veneered enclosure houses two 8-inch aluminum wave surround woofers, a 7-inch aluminum wave surround midrange driver, and a 1-inch aluminum-manganese tweeter. The Ergo 690 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.
