you continue to apply too much power, you’ll hear the sound
level reduced by a noticeable amount. You should then reduce
the signal level to the speaker system. Within a short time, the
circuitry will automatically reset and will return to normal
operating capability. Unlike many other protection circuits,
there are no fuses or other user-serviceable devices in the

as provided by the CSX40, CSX50 and CSX60 subwoofers.
A very special feature of these products is that they have built-
incrossoverswith high-passoutputs. Thismeans thatyoumay
use one channel of your power amplifier to power both a

able load on your amplifier. The amplifier only sees the
subwoofer/crossover load which is 4 ohms for CSX series
subwoofers. Without the built-in crossover, the combined
impedance of full-range and subwoofer speakers in parallel
wouldbemuchlower. Manyamplifiersarecapableofpowering
verylow-impedanceloads,butsomecannot. Thisfeatureneatly
addresses that problem. Also, the high-pass crossover output

the full-range speaker. This prevents distortion (and possible
damage)fromexcessivelow-frequency energy gettingintothe
full-rangespeaker.
