    Welcome to the Polk Audio forums. The specs that I found for the MW-6502 are:
    Driver: MW 6502 Driver's model #.
    Brand: Polk Driver's brand name.
    Fs: 44.0000 Hz (Free air resonance)
    Vas: 1.2360 ft^3 (Compliance volume)
    Qts: 0.2790 Total Q
    Qms: 1.9700 Mechanical Q
    Qes: 0.3250 Electrical Q
    Sd: 0.0130 M^2 (Piston area)
    Xmax: 3.1800 mm (Cone excursion, linear)
    Revc: 3.5200 ohms (DC resistance)
    Znom: 4.0000 ohms (Nominal impedance)
    Pmax: 35.0000 watts maximum rated power

    As far as the crossover for the Monitor 4, there were several versions of the Monitor 4, as is true with most of the Monitor series. Your best bet is to pull the mid-woofer out and look at the cross-over component values. Post a picture and we might be able to provide more help.

    The schematics for the vintage Polk speakers are located here: https://forum.polkaudio.com/discussion/38755/polk-audio-speaker-wiring-schematics-amp-more-all-models-except-sda#latest
