  • Tritrix TL build photos

    I'm just about finished with my Tritrix TL build, so i thought I'd post some photos of the build. First, obviously, thanks to Curt for providing such nice and complete build information. Thanks also to my generous neighbor with the minivan (MDF trips)...I'd never have been able to do this without his help. Also to my dad, who loaned me a router, which also had a circle cutting jig. I think I'm the last one to use this router, about 25 years ago to make a 6' tall stereo cabinet. The circle jig had never been used!

    My cabinet design keeps the acoustic path the same as Curt's original TL design, but I added 1 foot to the height (underneath). This raises the tweeter to ear level. The enclosed space under the TL holds some sand for stability (as if lugging these around isn't hard enough without an extra 15 pounds!). The bottom chamber holds the crossover, and is open at the bottom. This allows great access to the crossover. The bottom braces have T-nuts in them, to allow various finishing touches to the bottom. I originally planned on a solid plinth (which I've built), but I've decided to make aluminum outriggers with spikes (I have access to a milling machine).

    Since I live in the real world, I'm adding grills. A neighbor came over while I was first listening to the clamped-together speakers and he tried to poke his finger into the woofer. I guess if something is out in the open, someones going to poke at it! I thought kids would be the problem, not adults. I've finished the grill frames, so I just have to apply the fabric.

    Finishing was done with latex primer and paint, applied with a roller (to keep with the low-budget aspect of this speaker)...just like finishing off the living room walls. Simple, and it gave a very nice textured finish. A lot easier than spray cans, and a lot cheaper. I used satin black paint. I originally wanted to paint them bright red, to make them stand out in the room, but the WAF changed that decision. I don't regret it. The black looks nice.

        I did one this way and I am happy with the way it turned out. I find that latex is very fragile... Due to the nature of the paint I used a low sheen topcoat. It is a lot more durable now.

          I'm trying to think of tips to help other new builders (this is my first build...Statements are next!).

          Make as many cuts oversized, then use a flush trim routing bit. This saves tons of sanding time, and your panels don't have to align perfectly. Of course, on a lot of boards, accurate cuts will save you a lot of pain later on. Spend a lot of time making really accurate cuts. My shop is very limited, so I had to use a hand held circular saw with a saw board.

          In one of the photos, you can see some Harbor Freight pistol-grip clamps. These hold things, but their clamping power is WEAK. Go with a better brand (Irwin, etc.) for pistol-grip clamps. Screw-type clamps are MUCH better for glue joints. I found that Harbor Freight screw clamps worked as well as some borrowed Jorgensens. The Jorgensens were definitely better, though.

            I forgot to mention using Seal Coat wax free shellac prior to priming. I coated the inside of the cabinet with one coat, and the outside with two coats. Gotta seal the MDF before paint!

              Looks solid, well-braced, nice paint job.

              Nice work!

                Thanks Lunchmoney. I have to add that your builds have been a major inspiration to me making these Tritrix speakers. I love looking at your build photos. I drooled over them for quite a while. Once PE put the Tritrix parts on sale, I immediately got out the credit card.

                  Your Tri's look really nice, great work. I bet they are fun to move around! Your right on stray fingers....adults do tend to be worse then kids. Dome Tweeters seem to be a strong magnet for poking fingers!

                    Another tip for beginners: To help with 90 degree joints, use 90 degree clamps (Lunchmoney's build thread shows some good ones) or anything with a reliable 90 degree angle. I clamped some precision 90 degree aluminum trusses used in optical assemblies (overkill) that I had in my basement.

                    Pistol grip clamps hold things together, but the screw clamps provide the real clamping.

                      right angle clamps... $9 at home depot... note one on each side... they work great

                        Great looking build. They look like the came together a lot nicer than my current statement build. Then again, this is only my third build and my first not that rushed build.

                        Good work.

                          Are you satisfied with the way they sound?

                            I really like the way these Tritrix TLs sound. I am very pleased with the results. I highly doubt any $200 store-bought speaker would come close to the quality of the Tritrix.

                            But for me, it wasn't about making speakers that beat the manufacturers. I mainly made the Tritrix to see if I could make nice cabinets with the very limited tools that I own (and borrowed)...a true budget build. I also wanted to see if I enjoyed making them (I did) before going on to something big. I was looking for a fun project that would be useful when I was done...building speakers seemed like a good choice (and it's a lot less expensive than a project like restoring a car).

                            I cannot make critical comments, though. My only reference is a pair of 26 year old AR45s (a 3-way with 10" woofer) with new surrounds on the woofers. I like the Tritrix better than the AR45s (anyone want some AR45s?). I do not have a lot of listening time on various speakers.

                            My next project is a pair of Statements. After they are finished, I'll hopefully gain some knowledge into fine sounding speakers and be able to comment more on the qualities of different loudspeakers.

As a former long-term employee of a local high-end audio store, SQ was the main reason I got into DIY...not mainly to save money, but because with all the mid & uber-priced speakers I've heard and sold, it was a listening experience with some Speakerlab DIY designs that convinced me you could get better SQ for less money. Besides, what I saw and heard with some of the high-end speaker companies was, well, not what you'd expect for the high price tag. I built a pair of Curt's TriTrix ported 2-ways in a .25 ft3 cabinet and they trounce similar offerings from the retail market that cost 3-4 times what I have into the TriTrix's...even with some factored in for my time. The Statements are on my short list for a nice higher-end DIY design...the designs I've built have been more budget-oriented, but the SQ belies the modest amount of time & money I have in them. Again, very nice work! I look forward to seeing the Statements come together.
