  • Maybe I didn't state it correctly this time. More or less, I want the box to be no larger than 1.25ft^3 volume, and everything has to be inside of it. There aren't maximum dimensions allowed or even preferred, just stating that the enclosure sets the size, and nothing sticks out of it. You are correct in your thinking about how it should be viewed.

    If you alter a driver, the added cost of what you do to it should be added. If you machine your own waveguide in the baffle, then it does not add to the cost because nothing as purchased. If you purchase one, then it adds. If you print it yourself using a 3D-printer, then you are building the waveguide yourself, and it cannot be purchased; however, I would think the cost of the filament might need to be added, due to adaptation/modification. If you farm out the printing process, then the manufacturing/purchase cost should be included. This is indeed where that edge gets fuzzy, as it in effect is "what was done by whom?" rationale. Make sense?

    • Thanks Ben.

      I think it's clear on the waveguide and box volume now.

      I'm also talking about making my own driver. Based on the guidelines for the waveguide, you're talking about including material (e.g. 3D printer filament) costs. At low buy quantities, this makes it difficult to "manufacture" a driver at this price point, even with just material costs. Nonetheless, I'm seriously considering it anyway. Thoughts?

      • I don't have a problem with you making your own driver, but with one caveat- the design must be repeatable. If you cannot order more of what you make or machine, or someone else can't get/make one, then it nulls the repeatability factor.

        • I have focusing on fishing for the past few months so have not posted here. I'm still fascinated with speaker building though, had a truly great time at InDIYana 2018, and think that the Bare Minimum challenge will be super. If the event is in March or April I plan to attend and hope that, just maybe, I'll be able to build a pair that I can ship up. The size and cost constraints of the theme make it a lot more feasible for folks to attend and enter the challenge who live too far away to drive. I'm excited!
          Best,

              When will be decided in December, but it is normally in April.

              • Ben,

                A question on the contest (sorry if this is already addressed in the previous 9 pages). Does the speaker need to be pretty full-range, reaching pretty low on its own, or can the build be a small desktop speaker expected to be paired with a subwoofer and there will be a subwoofer provided at the event to simulate this situation?

                  It needs to stand on its own. Adding a sub doesn't really show us what the speaker is capable of. The speaker is judged on its own merits. This really levels the playing field. If the smaller builds are allowed the use of assistance, why couldn't the larger units as well? If we did, then what we are judging is more the integration between sub and various speakers with no time for real adjustments. Not really fair for anyone.

                    Thanks. I agree with everything you said. I just wanted to make sure.

                    • I know several others are using Rival components for midbasses. Be advised that the current sale price, and the double-that former price for that matter, are not actually their retail cost. These are being sold below retail, and are usually considered on sale. I'm not trying to split hairs here, but this particular vendor is selling at greatly reduced cost. I'm just making sure the playing field is level. If you have questions, please PM me.

                        • Cool. Looking forward to seeing everyone again. Still working on my SideTowers. Warmed up close to 50 today (Wisconsin) and will be close to 50 again tomorrow. I could almost go outside and paint my speakers tomorrow!!

                          • Same here Bill. I definitely plan on taking advantage of the nice weather and making some saw dust (since I do all my table saw and router work on the driveway).

                                little, can you repost the final rules again in one post? This looks really fun and I'm going
                                to be there. I might even bring the PeteZilla's for fun.
