Acoustic Research designed this three-way crossover for the high-end AR 428 PS four-way speaker with active subwoofer. Save nearly half off the original retail price--the inductors alone are worth nearly $20--through this Parts Express exclusive factory buyout. All inductors are solid core type. The tweeter capacitor is poly.
A 6,000 Hz 2nd-order high-pass (approximating a Bessel slope) for the tweeter uses a 0.15 mH inductor and a 4 µF capacitor. An L-Pad is formed using a 4 ohm resistor in parallel, with a 1 ohm resistor in series. A polyswitch resetting fuse is included for tweeter protection.
For the midrange section, a 400 Hz, 1st-order Butterworth high-pass filter uses a 55 µF capacitor. The 3,000 Hz 1st-order Butterworth low-pass uses a 0.45 mH inductor.
The woofer section features a 4 mH inductor and 20 µF capacitor to comprise a 2nd-order, 500 Hz low-pass filter that follows a Linkwitz-Riley slope.
See the Manuals/Resources section for a crossover schematic.
