Beskrivelse
The CHR-70A (Gen. 3) is now up-dated 4 times since the first model was launched 4 years ago. Its usable frequency range is class leading. Depending on enclosure design, its capable of operation from 40Hz to 25-kHz.
2 developments further improve the design. An excursion limiter (arrestor) has now been fitted inside the motor sub-assembly, significantly reducing the risk of over-driving damage. The CHR is now capable of being driven at higher loads making it suitable for more audio applications. Colour coded custom locking connectors are now included in this design.
The driver has medium efficiency of 85.5dB at 8 Ohms making it easy to use on nearly all small to medium power amplifiers.
