    Default Difference between POLK BD 651 & 651S

    Some of the wise folks on here probably know this already but could be good info for us Nubes.
    This webpage shows the difference in the POLK BD 651 & 651S speakers physical profile.
    http://www.lotustalk.com/forums/f133...s-db651-90072/

    Apparently the DB651 speakers protrude out 3/4" further than the DB651s.

    I really don't think that would be an issue for our boats though.

    So, not a huge difference for cabin speakers, huh?

    I think the SC boats are fine either way. I didn't have any issues with my DB's.

    Why is there so much space back there? I could have used another 1.5" of interior space.

    Hi Kane, doesn't look like it. I had mistakenly thought that the DB651S (slimline) was shallower - but no just doesn't stick out (the tweeter) as much - so a smaller grill.
    I don't think it will matter if the grills stick out a little???

    Polk Db series will fit the boats just fine. I have the larger (and much heavier) MM650 MoMo speakers in mine without issue.

    The reason they have a Slim design is meant for cars. They wanted to be able to cross over to more markets and a lof of the new cars with there thin doors cant hold a deep style speaker very well.

    As for the boats the place that has the least amount of room is the Bow speakers and even in there i can slide my finger behind the speaker. I have the new Exile cabins and they are deeper then the Polks.

    I loved the Polks i had and now there in my truck.

    If you want to throw some money away buy the shallow depth speakers. I say buy the regulars and put the savings into beverages
