HiVi RT2C-A Isodynamic Planar Ribbon Tweeter — Includes Install Kit

HiVi RT2C-A Large-Format Isodynamic Planar Tweeter — With Installation Kit. The HiVi RT2C-A challenges the limitations of conventional dome tweeters by delivering true large-format planar performance. Measuring nearly 7 inches in diameter, it is an absolute giant among planar tweeters. This isodynamic ribbon utilizes an ultralight Kapton film diaphragm for a nearly perfect transient response. The large radiating area permits a relatively low crossover point between 2,000 Hz and 3,000 Hz, making it easy to pair with larger 6.5-inch or 8-inch midbass woofers in high-end 2-way and 3-way systems. Acoustically, it offers exceptional efficiency and dynamcs. For crossover designers, the RT2C-A solves several common passive network headaches. Because the conductive trace is an etched planar surface rather than a wound wire coil, voice coil inductance is practically nonexistent. This yields a flat, purely resistive impedance curve across its operational band from 1,700 Hz up to 30,000 Hz, meaning you won't need to add impedance-flattening Zobel networks to keep filter slopes predictable. The tweeter has a heavy, rigid cast aluminum front flange with an integrated acoustic flare to optimize horizontal dispersion while controlling vertical ceiling and floor reflections. To save you a trip to the hardware store, we include a custom-matched Installation Kit at no extra charge so you can start building immediately. Each tweeter you buy comes with a pre-cut gasket, two quick connect terminals, and screws for free. Highlights Ultralight Kapton Planar Membrane: Delivers extended frequency response up to 30 kHz with rapid transient response and zero dome-resonance colorations. Push-Pull Neodymium Matrix: Symmetrical magnetic field distributes uniform force across the entire diaphragm for ultra-low second- and third-order distortion. Massive Cast Aluminum Flange: 176mm diameter heavy-gauge cast frame eliminates flexing while managing off-axis horizontal dispersion. Complete Installation Kit Included: Ships with the exact matching mounting screws and quick-connect wire terminals needed to start your build immediately.
