Guess what my daughter put on her Christmas list? Speakers! So I ordered a X-LS mini-monitor kit from Danny yesterday. I've been wanting to try this and now I have a reason to do it.
Last night while searching on cragslist for building supplies to use on the build, I found a local shop with with a huge amount of 1 1/8" thick MDF cutouts left over from a large job they are doing. Guess what, they are just big enough to use for this build and they were FREE. They're big enough to cut out a 13"x 20" or 12' x 24" board.

So here is my first question. Since these MDF boards are 1 1/8" thick instead of the 3/4" called for in the plans, I am going to have to make some adjustments. I'm not sure which dimensions are OK to change and which ones are off limits. I assume the front baffle width is off limits, right? Can I just make the speaker sides deeper so the internal volume stays the same? Hope this makes sense.
p.s. anybody North of Atlanta that would like to pick up some of the boards, PM and I will give you the details. He has hundreds of them available.
