  • "Rock Its" Build Thread

    I got started today on my "Rock It" speaker design.

    Here is the final design I came up with. The burgundy will be wood. The light gray will be brushed stainless steel and the black will be black paint. I plan on coating all the surfaces with pour on epoxy. It will have a high gloss shine.



    Paul K. designed an MLTL for me thanks Paul. That will be in the bottom section of the speaker.



    Here is what I have in PCD. Once I build the boxes I plan on taking measurement with the drivers in the boxes and recheck my sim.




    I cut up a 3" x 6" x 9' piece of hickory for the sides but didn't quite have enough, so I cut up a 4" x 4" x 6' piece of black walnut. I put it in between the hickory to make my panels wide enough.


    Here they are glued up.




    This should be a fun build and a really good learning experience.

    You're welcome. I know it will turn out really looking super and I hope the sound matches its looks and finish.

        More progress.

        Angle pieces cut on the table saw. Free hand! This was about the same point in the project with the Nightmare Speakers that I was wondering WHAT I WAS THINKING! :eek: I have about four hours in figuring out and cutting these pieces.




        These are the MLTL base units that will slide inside the outer cabinet. Much easier to build.



        Set into place. These will have torchdown roofing material added on all sides then once set in place I plan on spraying spray foam around them to couple them to the outer cabinets. I have about 3/4" for the roofing material and the spray foam between the cabinets.





        This pic is before I glued on the baffle. I plan on mounting the driver to this baffle then cover the baffle with torch down roofing then set the outer baffle onto it with hanger bolts. Woofer, mid and tweeter will be sandwiched between the baffles with the outer baffle removable from inside if I need to get the drivers out.




        Next I have to build the sealed enclosure for the mid and tweeter.

          thanks Dave for closely documenting these, it is going to be fun to watch such a complex project be put together by a true craftsman.

                  Nice freehand work with the table saw ... cabinet design looks well thought out. Keep the updates coming, they should be quite distictive when finished!

                      Thanks for the complements guys. Here is a little more progress putting on the roofing membrane. Worked out well.

                      This is the removable rear panel for the MLTL box. I still need to cut the vent. I inset the panel then wrapped the box and inside of the panel with the roofing membrane.





                      Set inside the main cabinet with about a half inch to foam around the inner cabinet. I will have a removable panel on the base cabinet and the mid cabinet then another rear panel that will fit the whole back of the speaker with a layer of roofing membrane between.



                      In the left cabinet you can see the rolled up membrane. This is how I put it on with the speaker laying on its side. I heat about two inches of the end of the roll then stick it in place like in the pic. Then apply heat between the membrane and the cabinet then as the membrane starts to melt I roll it out slowly. Seems to work best this way. Same method as if you were applying it on a roof.



                      Set in place with the driver cut out. After I put in the foam I am going to add another layer on the face of the baffle so it will stick out about a 1/16" past the driver. When I apply the front baffle it shouldn't come in contact with the driver.





                      Oh almost forgot Arlis my shop was just blown out with my air hose. I wish the vac system kept it that clean.

                        Re: "Rock Its" Build Thread

                        Started on the Mid/ tweeter box after work today. I changed it up a little. I got rid of the small black stripe were it meets the main cabinet. In order to do this the box is larger at the bottom then the top and wider at the back then the front. Lot more angles and work but I think it will look better.


                        I was planning on putting the crossovers in between the two boxes but since I widened the bottom I don't think they will fit there now.

                            Thanks. I should be fast at it since I pretty much work with my hands all day. I really try to work slow on my speaker projects. It's about enjoying the build. It is very hard to do being a self employed remodeler. Surviving is all about how fast you can do a quality job. I hate that!
                            I did get out this morning before work and finish up the other cabinet with the roofing membrane. The wife works late tonight so I should get the other mid/ tweeter cab built. Its already cut out I just have to assemble it. Nice and Ssssslllloooowwwwlllllyyyy. :D

                              What do you do with the speakers you build? You are certainly a great builder.
