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. Both these features are illustrated in the following page.
