Hi there, thanks for letting me in ;-)
I am from Denmark, but live in sunny south of Spain. This is the 10th country where I live, which meant a lot of international moving, which again meant getting rid of my Large and Heavy B&W speakers and ditto amps etc. But now, settling down, I want to experience that high end sound again. So cue Troels Gravesen Illuminator 5 project. But.... the WAF (Wife Acceptance Factor) was really nil on his build, so I decided for a total overhaul.
I liked several things about this project, they are time aligned, the quality of the drivers involved, the fact that Wilson Audio Alexx is exactly the same. I will be amping the bottom with a Hypex FusionAmp with active crossover and having a passive crossover for the mids and tweeter with external amp.
And now, after 3 weeks of spending every spare hour (read: 8 hours per day 🤣) designing and planning and drawing, the finalized design is done. The enclosures correspond to all volumes in the original project, but obviously the upper part looks (and will behave) very different from the original design, so.... crossover modifications etc. But that's more than enough for a later thread. Suffice to say that this is a complex design, and while paper is grateful, it also has to be possible to actually assemble the darn thing, so a lot of planning went into that.
For now, I'd like to ask here if anyone has experience with casting of Cabinets such as these mid-tone and tweeters. What resin or material did you use ? Molding or casting in 2 shell parts or in one go ? I am thinking along the lines of reinforced epoxy with chopped glass fiber, which should give a lot higher density and very strong modulus. But this decision is not set in concrete (wait, perhaps I should try that ?! 🧐) and I for sure would like some suggestions before beginning - which is sometime next weekend.
I enclosed a few screenshots of how the design looks like, and for sure I'd also love to hear all sorts of comments and advice on what problems you see in this, your solutions and basically whatever you can think of 🙂🙏
Very best regards, let the noise begin !
