    Default Larger in-boat speakers?

    Has anyone upgraded their in-boat speakers from 6.5's up to something larger? JL MX770s look interesting.

    Thanks!

    No but interested in the responses you get.

    Is the room? For one larger diameter and two deeper depth?

    That is a great premise. The added cone surface area of 7.7"s will give you improved midbass. Imagine a rim shot so dynamic that it can actually startle you a bit. It would also improve the integration between subwoofer and satellites.
    Beyond the basic premise, I think that the JL Audio MX650 (6.5" version) is the most musically accurate in-boat coaxial available. The MX770 improves on the midbass extension.
    Now the fit and installation is another issue. You need 7.75" of flat surface area plus depth. As I enlarged and upgraded the coaxial speaker I might also want to take steps to increase the rigidity of the mounting baffle. I'm skeptical in a '08 Moomba. Some people who went with an over-sized coaxial have totally replaced the existing coaming pockets with a new custom panel.

    I guess I will pull my 6.5's and measure... I think depth is more of a problem in the bow than in the main cabin?

    Jake, is that in an LSV or an outback or something? The interior is different than my XLV, I have two cabin speakers on each side, mounted under the cushion (in the "nook").
