      I love how it makes the 12" look tiny. I like the look of the driver itself, very nice!

        Yeah, the 12" looks small next to the 18, it doesn't help that it's a 12" driver in an 18" wide enclosure, whereas the 18" driver is in a 20.75" wide enclosure.

        Seeing the sub with the plywood front, really makes me want to take a stab at veneering. Something like maple. A light colored wood would be a nice contrast with the beautiful shiny black aluminum cone. But, it's a huge box. That would be an expensive veneering job!

          Dan,

          Put a finish on those Mandolin's! No wonder your wife goes to bed early when you start playing around with naked enclosures like a five year old kid with a bar of soap in the tub... :p

            Oh, I will! That is next on the agenda after I got this fully prepped for spraying. I hope to get it ready for spraying by June. And I have a surprise in store...

            Speaking of prepping, I've been working on the sub. It was hard to take it apart, but progress must be made.
            I skinned the top and back with 1/8" HDF (hardboard). I was able to flush the top with the front baffle, so it was pretty seemless.




            The purpose of this was to cover up seams and screw holes more completely, and to add just a touch more mass to the top and back panels.




            I did put a heavy layer of bondo on the inside of the woofer cutout. This is because there were several voids, one of which actually leaked out the side!





            Top top edges are chamfered, the front sides are 3/4" roundover, and all other seams will be 3/8" roundover. I have had some problems with the cheap plywood. The thin outer ply splinters easily and I've had some big voids right on the edge. I've used quite a bit of bondo and I have probably 2 more "coats" before I am fully satisfied. I wish there was a "thinning agent" for Bondo. Maybe I will have to get the "glaze".

            Just weighed it: 62.4 lbs completely empty.

              Looks great. Yup Bondo spot putty is good for the very minor imperfections. Takes longer to dry but it fills pinholes and such really nice and it sands like drywall spackle. What will the final finish on the sub be??

                I am going to get a quart of black acrylic, maybe semi-gloss. Spray it with an HVLP gun at my dad's place. It will have to be 100% ready for paint when I take it there, so it will have a chance to dry before I haul it back home. I will probably use a coat of sanding sealer, then several coats of Rustoleum gray primer first. I should probably also put some clear laquer on it. This will basically be a trial run for when I do the Mandolins later.

                I've been kicking around the idea of getting a marble or granite top for it.

                ETA: Anyone have any tips for cheap/disposable spreaders to use for applying bondo? It's a little messy.

                  You don't have to go the disposable route. Just get a couple packages of THESE. They are flexible so that when the bondo slop dries on the spreader, you can just bend and break the bondo off of it. I use mine many times over.



                  I also use a metal spackle knife for more precision spreading. On the metal knife, I just use a chisel to get the dried bondo off.

                    I've been doing Bondo, Glaze, sanding, rinse, repeat. I did about 6 rounds of bondo or/ glaze.

                    Now that it's started to warm up I hit it up with 6 coats of primer. I have determined that the Rustoleum "Painters Touch" Gray Primer is my favorite by far. I used 3 cans of primer. Sanded it between every 2 coats.

                    And now paint. I am using the darkest black color of Rustoleum Hammertone. I really like how this stuff goes on and what it looks like. Exceeding my expectations. I already drained 2 cans dry and I'm about to buy 2 more.















                    Amazing it looks this good considering what it looked like about a month ago with all those screws.

                    ETA: You may notice I put a thick layer of bondo on the inside of the cutout. This was to help plug the holes in that crappy HD plywood, which is full of voids.

                        That looks great. Understated, yet frightening.
                        There's a good chance I don't know what I'm talking about.

                          Yeah, it IS an 18" sub that can take almost 1,000 watts. I just realized that I am spending ($4 x 3) + ($5 x 4) almost $35 on rattlecans. When all said and done, Almost 4 lbs of paint and primer. I can weigh it when I'm done to see if that is right. It's kind of hard to move now, lol. Not only will it be over 110 lbs when fully loaded, but the size (20.75 x 19 x 27.125") makes it difficult to get a good grip on it. Downside to all this surface area is 7 cans of paint and primer. The hammertone likes to go on thick...

                          ETA: Wife likes the paint so much I might be painting "the Raven" 12" reference sub with the black Hammertone stuff so they match.

                          And it's time for some BASS:

                            Here's some more house-wrecking bass, I'll admit, my subwoofer is junk, and probably only reaches about 30Hz... I shall be building monsters.

                              Okay, so it's done now. Or is it? I buttoned it up. I did notice that the left side is a little rough, I think it needs another layer of paint. And I'm seriously wondering if I should do some Laquer on top. It's pretty shiny and the finish is durable, but it could be- more glossy? How durable is lacquer? Anyway, here are my preliminary finished pics. Poor lighting in the basement, I might take it out to the yard to get some better shots of it.


                              Speakon connector, air tight, with optional rubber gasket. Thing is tiny.


                              2 pieces of R13 fiberglass. 16" x 24" rolled up and stuffed in the back half. It makes a huge difference.


                              Next to the 12" Dayton Reference... which I have a feeling is going to get an overhaul soon.



                              I compared it to the Dayton 12, and it seems to have a much DIFFERENT sound. I think it is due to stuffing. The 12" has very little stuffing in it (as Zaph recommended). The 18" has the back half completely stuffed with fiberglass (and I'm thinking about putting some more in). The 12 sounds like it has a much higher pitch, almost sounds "hollow" but also with more harmonics. The 18" sounds very solid and deeper, with less resonance. Almost "dry".

                              I know that stuffing can smooth response and that it makes it seem like a "bigger" box, but is there such a thing as too much stuffing, or can fiberglass be stuffed too densely?

                                Wow, the Dayton looks like an 8" next the the big one.

                                Glad you are happy with the sound

                                How's the MSII?
