How can I tell if I have a bad driver or crossover?

I have two Monitor 70s (series ii), and I could swear something is missing in one of them. It's almost like there's not bass/low end on one. Any tips on how to single out the problem?

Thanks!

    Swap the drivers between the two speakers. That will tell you whether it is the crossover of the driver.

    Gently press the driver in with your fingers to see if it is frozen or it is rubbing. The driver should move freely and if it is frozen of rubs you have a bad driver.

    If it pulls to one side or the other when you take your hands off the wheel it's probably a bad driver. It probably just needs a front end alignment.I generally don't care for crossover vehicles so I won't comment on them. lol:
    If you can't hear a difference, don't waste your money.

    It can happen and would not be unusual if it did. Replacement Polk drivers can still be found, however replacing crossover parts is a lor easier.

    where are your towers located?

    i ask because, when i first got my polks M70 s2, i thought one was dead too.

    turns out because i had a tower in a corner, (have no choice) even moving it out 2.5 3 feet still amps up the bass of that tower versus the other one.

    i dont know your layout Kaz but this sounded like something i went through before and something for you to think about before pulling everything apart.


    lets hope its a simple fix.

    ESR:loneranger:
    AVR: Sony 5600ES
    Center: CS2II (Clarity Caps PX, Perfect Lay coil, Mundorf resistors)
    Front: Monitor 70 II (Clarity Caps PX, Perfect Lay coils, Mundorf resistors)
    Surrounds: Monitor 40 II (Clarity Caps PX, Perfect Lay coil, Mundorf resistors)
    Rear Surrounds: Monitor 40 II (Clarity Caps PX, Perfect Lay coil, Mundorf resistors)
    More to come :biggrin:
