The 670GTi’s spider and surround are specifically designed to ensure linear motion in both forward and rearward directions. This minimizes distortion caused by the speaker’s suspension.
The ultra-rigid Kevlar dustcap and cone body minimize unwanted cone flexing, ensuring smooth frequency response.
The 670GTi delivers crystal-clear vocals and midrange—even during heavy bass signals—thanks to its polepiece cap. The copper cap provides linear inductance over the full range of forward voice-coil travel, which reduces intermodulation distortion.
When air gets trapped in a voice coil, it can cause distortion—and the 670GTi isn’t about to let that happen. Vents allow air to move over the voice coil, which eliminates distortion and enables superior power handling.
An extra long, aluminum edge-wound voice coil provides high excursion for improved low-frequency capability. The two-inch diameter, over-hung voice coil reduces distortion at low frequencies and high input power.
The one-inch, edge-driven textile dome tweeter employs an oversized voice coil, which increases power handling and lowers distortion at high output levels, and produces a flatter overall frequency response.
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.
Technology and construction you might find in a premium home loudspeaker are right at home in the 670GTi’s crossover network. Aluminum-encased, wire-wound resistors and heavy-trace printed circuit boards greatly increase heat dissipation and power handling, maximizing the amount of amplifier power that reaches the woofer and tweeter.
