Tritrix Speakers

I just completed this project (the two speakers on the right). They were assemble from a kit from PartsExpress called the Tritrix. Normally, I don’t do kit speakers. The speaker on the left is one of my own design which I built a few years ago. In the background, you can see a smaller speaker that I built last year.

The Tritrix set is meant to be a present for my sister and her husband who have a bit of a tough year. The kit consisted of the speaker and crossover components and the cabinet parts which were CNC machined. The design looks like a straight box, but it’s a bit more complicated than that as these are transmission-line designs that have an internal channel to vent the speaker to the outside.

The part that makes this a bit more than just an assembly job is that this is my first large-scale veneering project. The cabinets are 3/4” MDF which is a standard for speakers. I purchased a 4’ x 8’ sheet of paper-backed Sapele veneer. The veneer is applied using water-based contact cement. I’m exceptionally pleased with the result. The seams at the corners are not obvious and the veneer was relatively easy to work with. The biggest issue was that the contact cement causes the veneer to curl as it dried which made application a little tricky. The finish is four coats of water-based polyurethane.

The sound quality is pretty good. Not as good as my own design, but certainly well worth the money. If anyone is interested in building speakers, this isn’t a bad way to get started.

good to see this kind of project around

nice job

The water-based cement dries really quickly and I saw no evidence of any water-related issues on either the MDF or the veneer. I don’t miss the fumes from the solvent-based cement.
