Punch Pro PP4/PP8-NT

The Rockford Fosgate Punch Pro PP4-NT and PP8-NT are high-performance 25 mm (1-inch) neodymium horn tweeters designed specifically for demanding car audio applications with high sound pressure levels (SPL). Thanks to their high sensitivity of up to 107 dB, they deliver exceptionally dynamic, assertive, and precise high-frequency reproduction.

The combination of a high-performance neodymium magnet system, a robust aluminum diaphragm, and a precision-machined aluminum phase plug enables high power handling in a compact design. A heat-resistant Nomex voice coil and the sturdy die-cast aluminum enclosure ensure reliable performance even at high volume levels.

An integrated 6 dB/octave high-pass crossover and interchangeable mounting flanges facilitate integration into high-performance loudspeaker systems. The tweeters are sold individually and are available with either 4-ohm or 8-ohm impedance.

Note: A suitable high-pass filter is required for safe operation. When connecting directly to an amplifier, Rockford Fosgate recommends an external high-pass filter with a cutoff frequency of at least 4 kHz and a slope of 24 dB/octave. The built-in 6-dB crossover does not replace this additional protective filtering
