    Default 2009 model sub vibration

    Any one having trouble with their sub on the 2009 models ? Mine works well but vibrates every thing on the driver side. I tried stuffing foam up under panel but does not help much.

    Default RE: 2009 model sub vibration

    I haven't took delivery of my boat yet so I can't comment.

    I am worried about having the same problem though. I'll chime in once I get my boat.

    Robert,

    As you know,

    For 09' factory places a Polk MM series sub in the forward starboard side coaming. The fiberglass appears to be thick and stout enough to support the sub driver.

    Unfortunately, the Polk MM is designed for a small sealed enclosure and performs poorly in a free-air application. Despite the assertions of Polk or any manufacturer there is no such thing as a multi-purpose sub unless it performs poorly in every use.

    Here are a few recommendations to try:
    1.) Zero bass boost from the amplifier.
    2.) Tune the sub crossover higher at 125 Hz, providing an increase in perceived output, and then gain the sub significantly down until it blends with the high-pass section without sounding remote or detached.
    3.) Use an in-line subsonic filter (35 Hz) on the low-pass RCA input to reduce the wasted and unwanted excursion.
    4.) Acoustically isolate the 6 1/2-inch coaxial that is mounted in close proximity to the sub (only one of six).
    5.) No equalization on burnt CDs or iPod files.
    6.) Close off any area down the coaming where the sub's front and rear isolation is circumvented (within a distance of five feet). This will better damp the woofer and reduce excess excursion and vibration. This may or may not apply to your 220.
    7.) Replace the sub with a JL Audio marine free-air 10-inch which is designed for this application and is the best in its class by a mile(or kilometer).
    8.) Build a front-loading acoustic suspension enclosure for a supplemental 8-inch (only requiring .35 cu. ft. displacement) and find an alternate location for the primary subwoofer (in a sealed box).

    Sorry I'm not bearing better news with an easier solution.

    David, Thanks for all the tips that I can try. I talked with White Lake who talked with Correct Craft. I think they will have rethink the sub and location for the 2010 model year. For the 2009 model it will be trying the things you mentioned. Maybe you could share your thoughts with tect support at CC. thanks

    Sometimes it's a fairly narrow freq band causing the problems (or the worst problems). Someone from a pro audio outfit (or possibly a good home theatre or car audio shop) could help you do a freq sweep to analyze it and then test it with a parametric EQ or notch filter. This MIGHT be an easier and less expensive solution and would preserve broader freq response than cutting all of your low-end. Agree with David though, best would be an appropriate speaker for the application and using a speaker spec'd for a sealed enclosure in an open air situation is a huge no-no.

    Sometimes? - how about every time CC has done a sub it has been terrible! If you want the sub to perform you will need to sacrifice some storage and build a box!

    Has anyone tried any of the suggestions given by Earmark Marine. I was thinking of trying the JL Audio "Open Air" sub. Would this still have the load thumping bass that a typical sub would have?

    Default sub fix

    I have not tried anything yet . When I called about the free air sub that David suggested they asked if I knew what was behind the sub, I don't know , planning on taking sub out this week since snow board season ended this weekend in Va. and might do some dampening and then up grade to to the free air sub if that doesn't stop all the cables rattling. I will let you know if anything works on my end.

    Default RE: sub fix

    I believe there is a fiberglass hull with some carpet behind the Sub.

    Default RE: sub fix

    I have the same issue on my 210. The sub vibrates way too much where I will sacrifice bass by setting it lower in order to keep my boat and being vibrated to death.
