Seas Prestige 27TAC/TGB is a High Definition metal dome tweeter with a wide, soft textile surround and a rear chamber. Anodized aluminium alloy diaphragm with pistonic behaviour throughout the audible frequency range, resulting in a good dispersion also above 10kHz. A Hexagrid protects the diaphragm. Sonomex surround for low resonance and excellent mechanical linearity. Titanium voice coil former for optimum transfer of force from coil to dome. The non-conductive former also doesn’t add any damping to the excursion to allow a very transient sound. Copper cap in the magnet system reduces distortion and voice coil inductance, resulting in a sound without colorization. Optimized rear chamber and internal damping for a smooth and resonance free response.
