    Re: Ports and tuning...

    Where the length of a port tube becomes necessary to increase is more pronounced with flared ends as opposed to rounded-over ends. You may not have to make a very large length adjustment over what I modeled for you.

    Thanks Paul

      Hadn't had much time to work on the speakers in the last few days. Been busy catching speakers on fire or blowing up tweeters. Any way I ended up cutting the port in half and permanently mounting the one section in the back panel and drilled the inner half for screws to attach it to the stationary half. This way if I need to change length I can remove a section or add a section. Then once I get the right length I could always replace the inner section if need be.

        Re: "Rock Its" Build Thread

        Got some more done this week. Finished up the baffles. In the pic I have the drivers sitting loosely between the inner baffle and the outer baffle. Ready to throw some stain and sealer on them, a coat of black on the baffles, put the drivers in permanently and start measuring.

          I forgot to add. The piece of stainless I needed I ended up getting the kick plate from Home Depot. It matched really close. I was able to carefully cut it with a long set of duck bill snips. I think it was easier to work with then the laminated stainless. Thanks Dan!

              Wow Dave!

              Those are really looking nice. They will look pretty classy once you get the baffle finished.

              I'll bet you are getting anxious to hear them. I know I would be.

                Dave,

                Those are really handsome looking speakers! Will be curious to see how they match up with your sim. And how they sound. Hopefully you will be able to take them to Indiana next year. Thanks for sharing.

                  Thanks for the complements. I am really not in a hurry on this one. I just keep plugging away at it a little bit at a time.
                  I am spending a lot of my free time training at my water ski jumping. I have states in two weeks with regionals and nationals following that in Illinois.


                  Probably the part I am excited about on this build the most is the MLTL design and seeing what or if all the damping will make a difference.
                  I still have to get my measuring system working properly. I just haven't had time to spend on it. Hopefully I will have that ready when I move them inside.

                  It seems much more enjoyable when I don't try to rush it. I have really tried to take the production mind thinking out of this build.

                    Got a couple coats of Polycrylic on them. I am going to bring them in and start measuring one cab at a time and start putting the pour on epoxy finish on the other one. Hope that goes well. :rolleyes:
                    Dave

                    Pic doesn't do them justice. Very nice deep rich look to the finish.

                      Tried to get a close up to see the depth of the grain. Seems the flash is what messes it up. I will try some outside shots tomorrow.

                        Re: "Rock Its" Build Thread

                        I primed the panels with Bin 123 oil based with a foam roller pad. Figured if Dan liked it I would give it a shot. Sure beats pulling out a spray gun and cleaning up for such a small amount of work. Did a couple coats sanded with 220 then sprayed with a rattle can of Bronze Metallic Satin. Kind of neat looking. Looks black in low light but in the sun it takes on the bronze metallic look. I thought it might blend well with the red mahogany stain and the mid has kind of a light bronze look to it. I hope to get the drivers in one this weekend. If I do I will take one out in the sun and take a pic. Not an easy task. My daughter had to help me carry them down into the house. I would guess cabinets at a 100 lbs. with out drivers or front and rear panels. Either that or I am just getting old.

                          Get a hand truck and cover the bars with foam padding. Makes moving heavy speakers around much easier. I used some scrap roll bar padding, it worked great.

                            I do have one padded with water pipe foam, but it is 52 steps down to the front door then another 12 down to the lower level or I can go down the gravel driveway, that takes 4 wheel drive to get up without slipping, and down through the yard and around. With the hand truck it would be easy to tip over on the turns down the yard and seemed like a lot of work on the steps. So I chose to pull my daughter from in front of the tv and get her some exersice. :D
