It just seems weird to me to call the phenomenon baffle step diffraction, maybe it's just me.

Hey give Karlton a break!
I'm in a very similar situation, getting ready to put together a smaller sized set of DIY speakers and it's also my first serious DIY audio project. What are drivers do you guys like between 3" and 5"?

karlton,

If you want something that works well i.e. sounds very good, is not too picky about room placement, won't cost much, will involve a bit of carpenter skills, and requires no correction circuits (just 2 wires to the speaker terminals), then how about building a pair of Lotus BVR with the Mark Audio CHR-70 drivers. Drive them with a TA2020 digital amp which will put out at least 12 very clean watts per channel and this amp runs around 80% efficiency so you'd be using about 4W to 6W of electricity most of the time unless you crank it up loud (I assume you are running alternate/renewable energy sources). The drivers are around USD$100 a pair, the plans are here: http://homepage.mac.com/tlinespeaker...map-130409.pdf I don't think this combination will disappoint, in fact the opposite, it will blow you out of the water. There are many good designs out there, but this one is impressing me every day and a great place to start, (and maybe finish) hence the reply to your post.

Ian.
