I say go for the 15" plus mid and tweet. Nothing is more annoying than having speakers that just barf and fart when you crank it. Maybe try a 15" operating from 30-100 hz then a real fullrange type 6" or 7" driver to handle 100- 4500 hz, finally a compression driver /horn combo to fill out the top end. Im on my way to doing this myself for my main speakers in the livingroom. One thing though, give them a real nice finish on the cabinets. That way you can be proud of it as a whole not just on the sound. But thats just my 2 cents. Hope you succeed and enjoy whatever you build for years to come........until you get the "itch" again

That's what I'm thinking, and I'd definitely use the 6" mid. One interesting speaker design I saw was the electrovoice interface D. A downfiring 12" woofer, a 6" ported mid, and a wide dispersion horn tweeter.

I'm thinking I'll start with something smaller though, work a couple kinks out and get the hang of the process with a two way bookshelf.

Also, for materials, everything I read so far says MDF is the way to go. I've been talking to my friend, who is also into audio, and has a lot of woodwork experience. He thinks something like 11 layer birch ply would have less resonance, and that this is the way to go.

You could try a side firing 12", which would make the base area smaller as well as the frontal, and eliminate cone sagging.
A two way bookshelf is a great place to start. Tons of examples round here. Somehow i can't upload pictures on this site so this image is on dropbox. Its of my studio monitors im working on. https://db.tt/wcKzm8iH

I did some searching on this and read the debate. I'm new here so I don't know what topics are cans of worms. I'd have edited that part out after searching if I could edit my posts.

Baltic Birch is better and far more durable. MDF is prone to issues with expansion and moisture. Not the most stable material for the long haul. Primed and sealed up can help prevent these issues. There are threads where all this is contested, blah blah blah

The impression I got is both take different construction techniques to get the most out of them, and work with their strengths and weaknesses. Maybe Birch was liked a bit more, but I'll make up my own mind after much more reading.

EDIT: nice, first post that didn't have to be approved by a mod. And I can edit it!
