    Mid Q Tempest and modding amp

    I recently built a Mid Q design sealed sub for my 15" Tempest and I am happy with it (so far). I was reading in the amp instructions that it has an adjustable EQ bass boost, is there any benefit to do this modification? If so, what type of sources will it benefit? Any info would be appreciated.

    BTW, this Tempest ROCKS, glad I sold my old Klipsch Sub now!

    Without knowing the specifics of the mod, answering your question would be pure speculation. And that's something we don't encourage

        The boost mod would be beneficial; if you have run in-room frequency response plots of your subs output, and find it needs boost in the areas that the amp mods can provide.

          So, I would run a frequency sweep test and use my SPL meter and plot it? Noting any frequecy that is low and by how much and do a boost on that frequency. Of course, that would be after I break in the woofer, how long should it take to breakin the woofer?

          Thanks again,

          Jim

            Depends on how loud and how low it's being played. No more than a few days for most people.

            Go to this website and scroll down to where is says "MEASURING SUB SPL LEVELS & USING MICROSOFT EXCEL WORKBOOK' Follow the instructions from there.
