I've never done "nearfield" monitors. Not really. I've done a 1 driver, full range, 3" speaker with a filter network that I'm thinking of doing again for my computer...but that's just a cheap $19 per speaker project. Sounds good enough, but it's more like the DIY version of an HTIB. Except they sound better than an HTIB. I don't know your budget but Paul O'Neal has designed a few speakers for nearfield listening now that look very impressive and have earned praise from the PE tech talk board (tough crowd).
He posts here now and then under "poneal".

Alternatively, you can buy an absolutely excellent kit from NorthCreek Musisc Systems called the Echo! It has a wicked sounding, speaker in a small package. I use the nice silk tweeter in a few other projects. $36 for matching tweeters is a great dealt.

These guys know their stuff. The Echo won't have as much bass, but otherwise I think wouldn't be out of place beside the Totem Rainmaker - which is exactly what I thought of when I first heard this kit. Close to a wall with the midbass hump, they sound bassier than they are.

Throw in one of those 8", 70 watt subs for $100 for all materials and you're set.
