Punch AUDIOphile 2x-4

The 2x-4 Crossover is designed to be the "link" between
tweeters, and mid-bass and mid-range speakers. This com­pact 2-way crossover is designed to conform to the following
criteria:

• 2-Way Crossover network centered at 4kHz

• Uses Linkwitz-Riley 2nd order transfer function (12dB/
octave)

• Additional tweeter filtering uses a series notch filter cen­tered at 1500Hz to minimize the tweeter's resonant peak

• Also included is an impedance compensation network
(Zobel) that flattens out the gradual impedance rise above
10kHz

• Tweeter protection provided through a special compres­sion circuit
