  • Goldwood GRS 10SW-4 & E-10SP box

    Looking to make a small, inexpensive, low powered, sub for my gf's Ford explorer.

    Thinking about the Goldwood driver (PE #292-482) and enclosure PE# 260-628.

    But...blocking off the vent in that box, to make it 1.1ft3 sealed, after taking internal measurements of course.

    The driver displaces about .007, so after sealing, the enclosure will be right about the sealed recommendation of 1ft3, at f3 of 42Hz.

    I considered the 8in Dayton SD215A-88 8" DVC Subwoofer, with two passive rads, or the Dayton DCS205-4 classic.
    But can't get to an f3 that low when considering total cost.

    Opinions? Where only talking about 70-100w rms. Not building an spl machine. Just clean, flat, low and controlled. For about $50 total, this appears very good.

    That GRS driver is an excellent value. I think you’re on a good track. Should work well in an suv. Play around with sub placement in the cargo area, driver polarity, and which direction the driver faces ( toward trunk door, forward into the seat back, up, etc. its amazing how much the right combination of these changes and affect driver/cabin integration, especially in an suv. My starting point would be rear facing reverse polarity.

      Why not get a sealed box from the get go? The Scosche SE12CC is 1.25 cubic foot. You would need an adapter to go from 12 to 10 or just mount a new MDF panel on the front like I did with my son's sub. I had a clearance issue cause the speaker was too deep for the box so I added an extra layer of MDF. Sonic Electronix has the Belva MDFS1012 1.2 cubic foot box. What dynamo says x2. I've found the back corner pointing sideways into the trunk or pointing towards the back of the vehicle sound the best.

        Got any links? Trying to keep the build around $50, minus amp.

        I'm considering using a concrete form tube. Can get a 12x48 tube for around $10. Cylinders are are better sonically iirc. Not worried about looks. Couple cheap 13x13 square (to keep from worrying about rolling) mdf end caps, and im in it for less than I thought. I've been told I'm a whiz at cutting a circle with a jigsaw, which I do have.
        Smallest size is of utmost importance.

        Should be somewhere around 18-20inches long.

        ***EDIT***

        That scoshe is dirty cheap, but still needs mods for a 10. The Belva is about the same price as the ported enclosure, but won't have to modify it to seal it. Money saved, and looks well built! Looks like a good alternative! Thanks!

        Will have to see how much two 13x13 mdf panels will cost me to do a tube. If end price is more than $35, including glue and mdf, maybe some threaded rod nuts and washers, and a jigsaw blade, the Belva is the best option.

        I have a feeling cost will be about equal, give or take $2-$3. Than there's the time and work making the tube. I don't have much free time.
