No bass from monitor 10

I have been having trouble with one of my monitor 10s. I just replaced one of the mid drivers, i press on the passive and the mids move outward, couple of seconds to return to normal resting place. I turn it on and i get no bass. When i listen to the good speaker i can hear decent amount of bass coming from the mids but on my other one there is almost none. The passive puts out zero bass right now. Is this a crossover issue? If so, what value resistor/cap would i need to replace?

Thanks

    Hello,
    The first thing that comes to mind is that one of the 6.5" drivers is wired in opposite polarity to the other. Try removing the driver you just replaced and swapping the positive and negate wires around.

    No, the black wire is the positive. That's the problem.
