Single passive crossover for Punch Pro components

Overview

Our take on the Rockford Fosgate Punch PP4-X

Rockford Fosgate designed the PP4-X crossover to work with a Punch Pro Series midrange speaker and tweeter. The PP4-X provides low-pass filtering for a 4-ohm Punch Pro woofer (3,000 Hz at a 6dB per octave slope), while Punch Pro Series tweeters include their own built-in high-pass crossover (4.5K Hz, 6 dB/octave). Don't worry about that "gap" in the frequency coverage, as the gentle 6db/octave slope ensures that the final response is perfectly blended and smooth.

Versatile little crossover

It's easy to set up your system. First, you select which tweeter you're using (the 2- or 4-ohm model), and then choose from three tweeter levels (0, -3, or  -6 dB) to suit your vehicle. The PP4-X features two woofer outputs, in case you want to double up on your Punch Pro midrange drivers for some real fun. The PP4-X handles up to 125 watts RMS, which is what Rockford Fosgate recommends for maximum performance from the Punch Pro speakers.

The PP4-X passive crossover is designed for use with the Rockford Fosgate Punch Pro series midrange/midbass and tweeters. The crossovers are sold individually and each covers one channel (left or right). For the best performance, it'd be recommended to use the Rockford Punch Pro tweeters with this crossover, which you can view on our site here: http://www.crutchfield.com/p_575PP4T/Rockford-Fosgate-PP4-T.html?tp=49590 [ Larry  Nov 02, 2015 ]  Staff
I forwarded your question to an Advisor and they responded with the following: The power handling is 125 watts RMS total. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Jul 01, 2015 ]  Staff
The db settings are up to you - select whatever sounds the best. As far as the amp/speaker combo, that will work. I always try to match the amp with the speaker exactly, however as long as your amp isn't more than the speaker RMS, you should be ok. BTW, those tweeters are monsters - I bought a pair and had to send them back because they would not fit my truck. [ Michael  May 01, 2015 ]
I forwarded your question to an Advisor and they responded with the following: A crossover makes sure that a connected tweeter only gets high range audio and the woofer gets the rest. This one uses 3000 Hz as the divider frequency. Everything above it will be sent to the tweeter output and everything below it will be sent to the woofer output. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Feb 24, 2015 ]  Staff
