Each speaker is a single 215 mm Supravox 215 Signature Bicone full-range driver mounted on a clear acrylic baffle, with no crossover. It began in 2003 as a DIY project and was then built commercially: ten pairs were made.</p> <p><figure class="fig"><a href="transparence-dimensions.jpg"><img src="transparence-dimensions.jpg" alt="Photograph: a clear acrylic baffle on an aluminium stand, with the driver behind it.
