Ultimate-1

The heavy-duty frame employs three-inch diameter steel support posts, which may be filled with sand or lead shot to provide maximum reactive mass. The high mass of the frame system insures that all of the energy of powerful bass demands is converted to music, giving the tightest, fastest bass possible. The termination of the front and rear support posts taper to a point to provide optimum floor coupling.
     The standard finish of the frame is a catalyzed paint that provides a beautiful lustrous black finish. Other colors may be selected. Black Spandex grille cloth is standard, giving maximum acoustical openness. The interface electronics uses premium hookup wire and is the first to employ toroidal audio transformers.
     The membrane is the thinnest, lowest mass film commercially available, assuring large, powerful linear membrane excursions and silky-smooth extended highs. The internal structure of the electrostatic panel is constructed of laser-cut high density plastic for the ultimate in dimensional accuracy and environmental stability.
     Generally, the philosophy of a manufacturer of high-end products is to provide a product that will satisfy the majority of its customers. However, for the few customers who cannot betray their personal desires at any cost, a different approach must be taken. Since the inception of Sound Lab in 1978, we have continually made improvements. Many of these have been prompted by the customers, themselves. Some of the suggestions have been of a nature that would not appeal to the majority. Nevertheless, for those few who must "go all the way" we have devised the Ultimate series. The customer is invited to assist in choosing some of the critical parts, such as the type of internal conductors and speaker posts. The color of the framework and the type of grille treatment are other areas in which the customer may participate. In other words, the Ultimate is a specialized, customized product that bears the trademark of the owner.
