1999: launch of the first H-P with a diameter of 15 cm, a size not previously available at Scan-Speak (while many other manufacturers offer them). Special feature of the 15W: simple paper membrane, not pressed, with an exponential shape (curvilinear), and slits cut in the paper and glued together, in order to reduce standing waves and thus avoid having to dampen the membrane. New success and unparalleled sound quality.
