      Enjoy those Continuum's!!! They're phenominal speakers. Oh, and I'm partial to the color orange as well ;).

        I took them outside today to catch the sun. I went from not enough sun to to much sun. I did get a couple shots that are ok.

          Good news, they are done!

          Bad news, they need to sit about two weeks before I can wrap them up and send them off!

          I'd hate to have them show up with marks in the paint because it's to soft.

          I did make up some mounts so all you need to do is drop the woofer in and snug it down. The top of the stand comes off with one screw on the back side of the post so you can fill them with whatever you want. You could even run the speaker wire down through the stand if you want.

              Re: Continuum Speakers Using my Trench Method on the MDF Seams

              John,
              I went to an old friend that owns several automotive paint stores in the area. He's like a world book of knowledge with auto finishes. He told me body putty is body putty. It's all the same.
              I can tell you it was USG Feather-rite. It was very creamy. I finished up a few spots with some Bondo brand that I had left over from about a year ago and it was no where near as creamy as the USG. So I don't know if it was just old and thickened. As far as getting it on smooth I would just have to say mix up only as much as you can work in about 2 minutes time. Get it on the surface fast and thick. Scrape the excess off you blade then start scraping it off the surface by holding your blade on a steeper angle then what you put it on. I start at one side and work my way to the other side with top to bottom scrapes. I would do an area top to bottom and if you run out in the middle of the panel let it set up. Then pick up from there and finish the rest of the way across the panel with a new batch. I find if you scrape from top to bottom in one motion you get a flatter surface. If you start and stop in the middle you will get humps that will have to be sanded out and it makes much more work. The thinner you keep the coats the less excessive sanding you will have to do. As I get the surface flatter with each coat I will end up with the blade almost 90 degrees to the surface scrapping it smooth. I've done a lot of drywall work through the years so I have an advantage getting it on smooth. You would be surprised if all you are doing is covering the MDF to seal the surface it only takes a very thin coat. on the corners I apply it 90 degrees from the corner dab it on fairly thick then clean your blade off and run up and down from top to bottom working from the face of one surface around with several strokes until you get to the face of the opposite surface. It's best to keep the corners thick, 1/16' to 1/8", because it will sand off the corners very fast. On the end grain it only takes a very thin layer to fill it and primer will not soak in at all. On coat will probably do it if you get the mud smooth. Spot putty works well too to fill in small voids and pits.

              Hope that helps.
              Dave

                Thanks Jeff,
                I think the Continuums lead the pack in how many different variations are out there of the same speaker.

                  Those are so nice. I take mine in British Racing Green and a yellow racing stripe on the stand... After I save up my money that is.

                    Question: How do you hook them up? I don't see terminals in any of the pictures.

                    Great look, Dave. Bold and bright. Very nicely documented process of preping mdf for painting. Thanks for sharing this.

                      The new owner will install the terminals when he installs his drivers and crossovers. I just dropped my drivers in one for the photo shoot.

                        Dave those turned out beautiful, and good reminder on waiting a while after color coat to let it harden.
                        Don't listen to me - I have not sold any $150,000 speakers.

                          Dave, how are the woofers attached? I didn't see it in the previous photos. Typically, there's a through-hole screw for them...

                              Good point I forgot about that. I used #10 hanger bolts. It's a good idea to put these in first since the baffle is only 3/4" thick as you turn them in they can leave a dimple on the baffle face. Easy enough to sand flat before finish. I predrill the holes to make it much easier. I would also suggest using Seal and Peel between the baffle and driver for a good seal. If weather stripping is preffered I would get as thin as possible so you don't have to torque down to tight. I put felt pads on the blocks since the driver is flush to the back side.
                              I also made the driver hole smaller then normal and used a 3/4" round over around the driver instead of a 1/2" round over.
