So I think I am going to do two designs. One Sealed. One Ported. I am leaning toward lilmike's thinking above I posted for the ported, with a tune in the high 40's. For Sealed, I am thinking I want to go smaller side but with still great results.
The reason? Because my theater is not done yet, and it's taking forever to even close on the land so I can start the pour so I would likely use these a year or so in my current smallish living room and the space is an issue. The sealed fit the easiest for sure, size can be smaller. I also think it would be cool to compare them, (sealed vs ported) and measure and give my opinion on them. That could be fun.
So I need to finalize two designs, one sealed (smaller) and one ported (optimal). I can do different things with each if I want. I'm having a tough time deciding and navigating between:
BigDaddy Roundovers vs say screw it and baffle wall the theater. (I'd do simple 3/4" material baffle roundovers anyways)
Open vs enclosed top / waveguide
I'm thinking roundovers on the sealed since it's going to be used without baffle wall. Leave the ported alone for now, with idea they will be placed into some type of baffle plate or wall, or that the environment will be built around them for optimal performance. Can I make a baffle wall slant? Like for the LCR plates can the entire wall toe in on the sides? (I am not sure I am explaining this)
I might try some sketchup (I suck with it).
