All speakers of the Capello, Elargo, Berlina and DARC series are available in a special version, which we call the Double Vision version. Here we use even more finely selected components from Mundorf, higher quality internal wiring, top quality WBT terminals and rhodium-plated bi-wiring bridges instead of the gold-plated ones. All this means that our speakers sound even finer, even more spacious and give you even more musical enjoyment. An investment that really pays off. The Double Vision version is so elaborate that it cannot be retrofitted. Please specify this when ordering!
