Super-strong Neodymium offers extra efficiency and linear field density. Extremely thin diaphragm for maximising signal fidelity and extra response Low distortion factor, good power-handling capabilities, flat impedance. High linear impedance and amplitude response over a very broad range. Attractive silver rough-finish aluminium face plate with rubber grommet. Quality polycarbonate package with low stray flux for close to TV use. Recommended minimum crossover frequency is 2KHz 3rd Order (-18dB) Higher crossover frequency will give higher system total power handling Ribbon mass 25mg, 960mm² 8x120x0.009mm Super strong 0.6 Tesla Neodymium magnet Impedance 7 Ohm, DC 0.02 ohm [Beware!] Sensitivity 98dB 1.4KHz to 40KHz and above Resonance frequency 440Hz Power 17W Normal, 40W Max Fascia 150x70mm Ultra-thin aluminium 5” (120mm) Ribbon Pair: SOLD IN MATCHED PAIRS PAIR EACH AURUM CANTUS G2Si RIBBON TWEETER SOLD IN SINGLES This tweeter utilizes a lightweight, pure aluminium ribbon to provide a super-tweeter high-end extension with exceptional detail, and quick transient response. The G2Si utilises Neodymium magnets and a heavy iron impedance transformer for excellent results. • High 96 dB sensitivity is great for efficient designs • Excellent high-frequency extension, can be used as a super tweeter • Extremely fast transient response allows reproduction of the finest details • Smooth and efficient frequency response from 1,700 to over 20,000 Hz • Recommended crossover frequency 2500Hz at 18dB per octave Impedance 8Ω Power 30Wmax Sens. 96dB F 1.7KHz - 40KHz Hole 110mmØ QTY 1 Code G2SI Ribbon Tweeters Colour Code Black JP2.0BK AS USED IN OUR HDSK SPEAKER KITS - LIMITED STOCK AVAILABLE ONLINE In the correct signal environment, Ribbon tweeters will excel for many years. However, Warning: Ribbon tweeters will destruct with DC and low frequencies. The soft aluminium ribbon will distort itself out of the flux channel and no longer function. Be very cautious. It is recommended to use a high slope crossover filter to protect the tweeter from low frequency and to test your circuit with another tweeter before committing the ribbon to signal. You have been warned.
