Mechano23 Open-source DIY Speaker Review

I'm working on a cast resin baffle and cabinet kit. I'm hoping to produce it as a flat pack so all you have to do is glue up and wire the drivers in. Did someone here make a PCB board for the xover already?

ooh I'm definitely interested in purchasing that!

Nice.

I'll probably pour the mold this weekend. There have been a lot of delays due to parenting (spring break, doh!) and a vacuum pump that didn't work out of the box.

Here is the model in a mold box. You get an idea of what the integrated horn/wave guide looks like. This is 3/4" thick with slightly beveled edges.
You cant tell by this photo but the horn/tweeter attachment in there recessed into the mold box by about 1/4". There is a recess in the back of the baffle that easily allows the tweeter to be clipped on to the cast part. For simplicity the baffle was made in imperial but within MM's of the original design.

I need to decide on a mounting design for the back. I could just leave it flat. Wood glue doesn't stick to resin so it would have to be two-part epoxy. I think anyone who wants to build one will probably have a drill so maybe just have pegs molded into the piece. Simple for the end user to build AND cool looking are my aims here.

This design is a perfect candidate for a good Taiwanese/Korean OEM to release at the sub-700-800/pr range. The supply chain even makes sense, with the SB and ScanSpeak drivers.

Just like how Dennis Murphy found a very good Taiwanese partner for Philharmonic Audio.

I have constructed a box but does filling make a difference when measuring the individual drivers? Or can I make my polar measurements without filling the box?

The final measurements of the individual drivers, which are used to develop the crossover, are taken once the development of the enclosure, including the insertion of damping material, has been completed.

So yes: the damping material has to be already inserted when the individual drivers are measured.
