I am new here and have been quite impressed with what I have read here concerning Pi speakers. I would like to build 5 matching speakers for my system and would appreciate any advice as to which direction to proceed. Here is my list of concerns, not in any particular order:

1. Small size (the smaller the better)
2. High SPL's (I like it LOUD and CLEAN)
3. High sensitivity (over 100db/1w/1m would be nice)
4. Low cost (the best bang for the buck)

I will be crossing over to my subwoofer at 80 hz, so deep bass is not necessary. What model of Pi speaker do you recommend to best fill these requirements? And then, how do I get the plans to construct them? Thanks in advance for your help.
