    Docero project

    I'd like to make the MLTL version of the Doceros, which specify a 2.5" port (7.25" long). Parts Express has two ports advertised with a 2.5" I.D., but reviewers state that one is bigger (2.625"), and the other is smaller (2.25") for part of its length. Does anybody know where I can get a real 2.5" port? Are those size differences small enough to ignore?

    This is the 2.5" port I've used on some of my builds that works well. http://www.parts-express.com/parts-e...table--260-386 However, Meniscus should have a port that works well with the kit since it's their design. That said, the minor difference you're talking about in port diameter shouldn't make any difference at all.

    BTW, I've heard the Docero's at the Meniscus DIY event a couple years ago and its a very nice sounding speaker. I think you'll enjoy it.

      Perfect, thanks! If it's good enough for you, I'll take it.

      Glad to hear you liked the Doceros. I've never had a chance to hear any of the DIY kits, so it's just a shot in the dark for me.

        This is the fun part of the project: before I've made any big mistakes :P

        I hardly have any speaker building experience, but on other projects I like to veneer before construction. I noticed most speaker builders do it the other way around, so I thought I'd give it a shot.

              Found some time to glue stuff together this weekend. I bought some veneer a year ago 'cause I thought it looked interesting, and it might be enough to cover these boxes...

                How did you get the dowel holes so perfectly centered? Vise in a drill press after drilling a pilot hole?

                Did you use a Domino for the other holes?

                    Thanks! Things have been going smoothly, so I'm waiting for the other shoe to drop :P

                    I used a dowel jig that automatically centers the drill bit on an edge. It works best for rail/stile type joinery, but I rarely use it anymore. This was a good opportunity to get rid of some scraps (including dowels) that I had lying around.

                    Yep, the other holes are for Dominos. I love those things!

                        Red gum. I've never used it before, but it's domestic, which I prefer. I really dig the sapwood, but I wonder if it will look too busy on these little boxes.

                        BTW, I think I mentioned in another thread that I didn't want to do another painted baffle, but my wife said she likes the look of black baffles, so here's me eating my words.

                          At least from the pictures, a black baffle might work well in this case.

                            Well they look fantastic so far. I need to save up my pennies for a Domino...unsure which one I'd get though. Do you just have the 500?

                            Looking forward to seeing how that red gum turns out once finished.

                              Yep. It's shockingly expensive, and I could live without it, but I don't want to

                                It looks really handy. I have a whole list of Festool products to purchase over the next year or so, so I guess this is just one more to add to that list.

                                I love tools!

                                  Slowly making progress on these. I had a veneer problem, so I tried to get creative to make what I had left work. We'll see how it turns out...

                                  I also finished the crossovers last weekend, but apparently it's not a public design, so that's my excuse for the boring picture

                                    They might not be pro, but if nothing else, you could park a car on these cabinets (~9.5 psi).

                                        OP says, "This is the fun part of the project: before I've made any big mistakes".

                                        His craftsmanship looks 10/10, though. The use of a Festool is noted as well.

                                        Great work.

                                          Thanks for the kind words. I glossed over the part where I ruined the veneer on the second panel I glued up, forcing me to completely rework my layout with barely enough left to cover the project. That's the kind of thing I was referencing earlier

                                            Got the ports fitted, and started working on the front baffles I had some extra plywood lying around, so I made them 1.25" thick.

                                            I don't know about you guys, but after sanding, lippings are my least favorite task . In any case, I'd was thinking of doing a chamfer or roundover, and I thought this would be easier than trying to wrap the veneer around.

                                                I was aiming to finish the baffles this weekend, and got 90% of the way there. I don't have any measurement equipment, but I gave them a quick listen, and I like the way they sound so far. Not surprisingly, they have more low end than the Speedsters, but perhaps more significantly, they aren't as laid back, and they sound bigger.

                                                BTW, I was thinking about replacing my old Rotel integrated with something nicer--any suggestions? I'm planning to stream from a Mac Mini, so I was thinking about something like the Parasound Halo integrated.

                                                  Very nice solid build, your skills a very evident!

                                                  Take a look at a Hypex NC400 dual mono amp kit, you can order modules and build 2 mono amps in one case or 2 separate small cases. They offer their full kit, lots of builds on the net. Of course not sure if they are in your budget.

                                                    Thanks! I'm pretty ignorant about this hobby, but I'm really enjoying this project. It's slow work, and I think I can appreciate how much effort you Ardent builders have put forth!

                                                    Building an amp kit would be fun, but it doesn't look much cheaper than the Nord stuff? I don't know anything about these amps, though. I also don't have any engineering experience. Are these kits complex?

                                                    I haven't settled on any particular budget, but a used Parasound looks to be roughly 1.8k. I'm hoping for balance, remote volume/mute and a USB input in whatever solution I decide on; compact form factor is a plus, but not necessary.

                                                      These are fairly easy to build, Nords stuff is his case with input changes like the regulators and OP amp rolling. A simple NC400 build with Hypex kit is $1,500.

                                                      Not sure what your source is DAC, CD? A stand alone DAC can have volume control and remote or you can add a preamp. The Parasound if matches the power you need does give you that all in one if your only wanting integrated.

                                                        Right now I've got an Airport Express plugged into an old Theta DAC, playing through an old 100wpc Rotel integrated. I don't need loud, but I would like something cleaner.

                                                          The baffles are attached now, so there's no going back. Some detail work still remains, but I feel like fabrication is nearly complete.

                                                              Not much progress to show on these, since I've been working on details and sanding. I decided to try "ebonizing" the baffles instead of painting them. So far, so good, but this is the first time I've tried this.

It takes a fair amount of time to figure all of that out, but the end results are worth it, I think. However, most people never even notice.

                                                                            It can be your little secret.

There's nothing wrong with them, but I just feel like building again. I've never heard any of the DIY designs, so can anybody suggest something with a similar-ish footprint? (8.5" x 11" or so)
