ETON 3-212/C8/25 HEX

The 3-212/C8/25 HEX from ETON is a 3" (8 cm) midrange driver that impresses with its three-layer hexacone sandwich cone and offers a spatially open reproduction with neutral sound characteristics. It is optimized for a frequency range of 100 to 5400 Hz and has a power handling capacity of 50 watts. With an efficiency of 88 dB and a resonant frequency of 57 Hz, it delivers reliable performance. The midrange driver has a robust mechanical design and weighs 1.2 kg, with a mounting diameter of 96 mm. Other technical features include the copper wire of the voice coil, which is based on Kapton, and a force factor of 5.8 Tm.

The 3-212/C8/25 HEX from ETON is a 3" (8 cm) midrange driver characterized by its 3-layer hexacone sandwich cone and offers a spatially open reproduction with neutral sound characteristics. With a recommended frequency range of 100 to 5400 Hz, this midrange driver is tuned for a balanced midrange preference. It has a 25 mm diameter copper voice coil embedded in Kapton as a carrier material and offers a power handling capacity of 50 watts. The mechanical construction with a total weight of 1.2 kg is based on a robust design with an installation diameter of 96 mm. In addition, the speaker is characterized by performance features such as an efficiency of 88 dB and a resonant frequency of 57 Hz.
