that was my first time working with fiberglass. don't be afraid, just do eeett! once you get going, it's pretty easy when cosmetics aren't crucial (carpet is very forgiving).
i had no plans, no guidance, i have never seen it done like that before, never seen a removable baffle before. i made it up as i went, inventing it. then i shared it with the world to help others improve on the design and give them something to inspire. the dates in my sound domain build log are real time, showing you what days i worked on it (nights and weekends). it smelled like resin for weeks though!!!
if you can use a drill, jig saw, and circular saw, you can do this. just make cardboard templates of the sides until you get the templates perfect. then trace and smooth the lines, then cut. i made my opening in four pieces because i couldn't get a single piece in place due to undulations and where i wanted the baffle.
wasn't much more work than making a permanent one, just a few more pieces. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
you could simplify it with a smaller opening, and then just have one larger square baffle that allows for a 10 or 12.
glad you like it. i love it. looking back, it seems like a lot of work, but now it's just there. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
