What should I cover the wall with? Should I just use sound board or get acoustic batting from ATS or something? I will black it out as well.
If you have incident energy from the surrounds encountering the front wall, it needs to be suppressed. That said, I'd employ rigid stuff, like 703 or equivalent. You've mentioned sound board, I'm not sure what you're referring to. Is that a rigid type product?
I like the 1.5" plywood front face. Inside the back-space, if possible, I'd fill the space everywhere except right around the drivers with fluffy insulation. The access door is a good idea, and obviously gasket the thing appropriately.Here's
a staggering good DIY theater, that implemented a pair of dual-opposed manifolds, with an access door. A nice build, and a truly herculean, first rate effort top-to-bottom...literally and figuratively
. Thought you may want to see how he executed the access, etc. Besides, the entire thread is a good read, albeit long. It's indexed for reference.
I hope the Fi IB3-18 drivers arrive unscathed. Mine were fine, but I was slack-jawed in disbelief upon seeing the modest packaging foam/cardboard. So heads up, ... maybe they've changed. Fwiw, I'm not sure I've ever heard of a shipping issue, so that's good.
