Javs, did you buy the cnc machine?
If so, are you interested in supplying a kit of some kind for this design, including crossovers (or at least, passive crossover design), or assist with sourcing the drivers?
Also, is the rebating for the drivers necessary for sound quality, or only aesthetics? If the latter, then I might go the cheaper and easier option and just mount the drivers on top.
I'm embarking on a dedicated home cinema construction - straw bale walled room under the house, soundproofed. Small 6.5m x 4.6m room, single row (with a second rear row perhaps). I'd like upgrade my speakers to DIY waveguides after the build but it makes sense to consider the audio now.
This would be my first main speaker DIY project. I would need nine of them, and then something for the ATMOS ceilings (x4) - DIY sound group's Volts kind of thing? Do you need waveguides for ceiling speakers?
