The Gauder Akustic ceramic series of high end audio loud speakers use ceramic drivers to render a large natural sound that is full of detail with a wide soundstage and pin point positioning. The cross overs include a 3 fold room equalisation switch (-1.5db, linear, +1.5db) for additional fine tuning. The speakers are down firing vented bass, closed mid/high cabinet, and sand filled. The ceramic speakers are available in a range of finishes, with black drivers, and  a choice of diamond or ceramic tweeters, either on purchase or in your home as an upgrade.
