Printing my tower speakers - Need input on speaker selection

This spring, I'll be using a 3D printer to print out my tower speaker enclosures. I haven't started the design yet because it's all up to speaker selection. I'm looking for input on this and would like to achieve the best and maybe loudest possible sound. However, I want to do this along with bragging rights on how inexpensive they are (I have free access to a 3D printer).

So, don't use the word Wet Sounds in your response. Let's limit it to Parts Express components (parts-express.com), or similar.

I'll be mainly wakesurfing, but would still like to hear the speakers when 80ft out. I've got 300W RMS per channel at 2 Ohms and will go as big as 10" speakers, if needed. Open to HLCDs or standard tweeters and multiple drivers.

Tell me what you think would be the ultimate setup. Drivers, tweeters, crossovers, etc.

Thanks for the help in advance!
