The following section has suggestions for use of the Punch Power Midrange Speakers in popular system designs. The information pro- vided includes our model numbers for 6dB and 12dB per octave passive crossovers and the crossover frequency to use with active crossovers. These recommendations all offer a satisfactory level of performance; however, since individual tastes vary, your Authorized Rockford Fosgate Dealer can help tailor the system to your individual needs.
PWR-34/44– Best used for midrange in a 3-way system with a woofer and tweeter. Model C-100 is the 6dB per octave crossover at 400Hz. Model MX-124 is the 12dB per octave crossover and allows use down to 275Hz.
PWR-38/48– Best used for midrange in a 3-way system with a woofer and tweeter. Model C-47 is the 6dB per octave crossover at 400Hz. Model MX-128 is the 12dB per octave crossover and allows use down to 275Hz.
PWR-54/64– Can be used as a woofer in a 3-way system or a woofer/ midrange in a 2-way system. The crossover point for use as a woofer/ midrange is determined by the tweeter crossover. Select a crossover that allows the two speakers to work together without overlapping. For use as a woofer, use Model TT-2.5 6dB per octave low-pass crossover at 250Hz.
PWR-58/68– Can be used as a woofer in a 3-way system or a woofer/ midrange in a 2-way system. The crossover point for use as a woofer/ midrange is determined by the tweeter crossover. Select a crossover that allows the two speakers to work together without overlapping. For use as a woofer, use Model TT-5.0 6dB per octave low-pass crossover at 250Hz.
PWR-408/808– Best used as midbass speakers in a 4-way system or as woofers in a 3-way system. In either instance, they require an enclosure in order to achieve optimum performance. To use for midbass a 0.25 cubic foot, sealed enclosure will fulfill the high-pass crossover function at around 100Hz. Use a passive low-pass cross- over to establish the upper operating limit (usually near 275Hz.) Woofer operation depends upon a ported enclosure of 1 cubic foot (for each speaker) using a three inch diameter port, seven inches long for a 45Hz tuning. This is generally used with a 6dB per octave low- pass crossover at 100Hz.
