As an aside, these speakers have taken me a lot longer than I expected! I didn't have a place or tools to do the job but was lucky enough to take a wood working course at a local community college. THEY HAD EVERYTHING!! Instead of buying lots of tools or getting someone to make it for me this was the best alternative. I made lots of mistakes, but if someone like me who had never taken shop classes in school (back in the day.. I won't say how long ago...) The instructors showed me what to do & gave me tips. Definitely top notch!! I strongly urge anyone in a similar situation to do the same. I had to make two trips to get both speakers home as my car is small!!

Use T-Nuts if you can. Those H290 mounting holes are close to the edge of the cutout because the lip on the H290 is kind of narrow. Wood screws will hold it, but if you ever go back in, each time those screws are removed and re-inserted takes some of the wood. T-Nuts are a much more durable fastening method.

If you want a big challenge, you can flush mount the horns into the baffle.
