The exceptional ability of the Model 7T surpasses the competence of conventional systems through its exacting design and the high quality of its enclosures, networks, and drivers.

Multiple layers of curved, stressed, and laminated MDF provide non-resonant behavior unmatched in conventional flat panel construction. Seven full cross section braces remove any remaining subtle coloration. The resulting labyrinthine structure is virtually inert.

Specially compounded Papyrus forms the stiff but precisely damped midrange cone. This driver is isolated in a separate, wool-filled chamber. The woofer cones are a rigid, damped bilaminate composite. Both driver types have cast magnesium frames, large magnets and long linear excursions. The soft ring-dome tweeter has large dual magnets, a damped chamber, and a copper pole sleeve. The result is that each driver remains linear well beyond its range of use, maintains accurate transients, and exhibits exceedingly low distortion.

Seamless amplitude and phase integration is provided by precision networks using 21 high-quality components including polypropylene film capacitors and low-oxygen copper air-core coils. High current nickel-steel cores are used in the bass. Separate glass-epoxy boards are employed for the bass and midrange/treble sections. Silver solder and Teflon® insulated high-purity copper wire are used throughout.

System performance is exceptionally accurate and natural with excellent transparency, detail, dynamics, and spatial presentation. Low bass has outstanding authority, control, and extension. Upper bass is well defined and articulate. Midrange is extremely natural, clear, and beautifully detailed. Treble is delicate and open, without edge or false emphasis.

Excellent coherence, three-dimensional imaging, and transient accuracy are provided by the wide dispersion, low diffraction, phase accuracy, and extremely low stored energy of the system. The result is a musical experience that is truly captivating.
