EXTENDED-RANGE DOME TWEETER

The 670GTi employs a full one-inch edge-driven textile dome tweeter. This advanced tweeter features an oversized voice coil, which increases power handling and

lowers distortion at high output levels, and produces a ﬂ atter overall frequency response. Another of this tweeter’s signiﬁ cant beneﬁ ts is that it allows a lower cross-

over point, providing a more seamless transition between the system’s woofer and the tweeter. This gives you far superior stereo imaging and ﬂ atter overall system

response, especially in the critical vocal range. At the other end of the spectrum, the 670GTi’s tweeter plays all the way out to 30kHz, so you hear every bit of detail

and nuance that your music has to offer.

PRECISION CROSSOVER NETWORK

The 670GTi crossover network features technology and construction that are more likely to be found in an expensive audiophile home loudspeaker than a typical car

audio component speaker system. High-precision polypropylene capacitors and air-core inductors that approach the ideal theoretical characteristics of a capacitor

and a coil are employed. precisely integrating the woofer and tweeter without adding a resistive component or other non-linearities to the signal. Aluminum-encased,

wire-wound resistors and heavy-trace printed circuit boards greatly increase heat dissipation and power handling, maximizing the amount of ampliﬁ er power that

reaches the woofer and tweeter.
