Passive radiators, ext crossovers & subwoofers

Do crossovers work equally well with speakers which include passive radiators?

This may be a silly question, but I asked it anyway. I don't know much about passive radiators. I have a pair of Polk Audio Monitor 7 speakers and I'm considering adding a subwoofer to help out in the lower frequencies by applying a crossover. If I set the crossover at 60, will the speakers continue to create sound at frequencies below 60? Or does the passive radiator create the sound only at the frequency delivered to the speaker?

Not sure if I'm understanding the question.

There's low pass and high pass components of a crossover. A sub, fed independently by interconnects, would only include the low pass filter, in which case the main speakers still receive full bandwidth. A separate active crossover, such as a NHT X2, includes both low pass and high pass filters. There are many ways to integrate a sub, including speaker level.

A passive radiator plays no part in your plans, except that it can be "tuned" or weighted (usually with blu-tack) to adjust the "Q".
