Edit: After finishing this thread and contemplating what I had written, I realized that it might give the impression that I'm urging builders to recess their drivers, and/or utilize rabbeted joints. I don't want to give that impression at all -- I personally like the rabbeted joints, for reasons I explain further on in this thread, but I recognize that they're not necessary and might be difficult if you're not equipped to make them. The same goes for the flush mounted drivers. Surface mounted drivers look perfectly fine, and are likely the best choice for newer builders when anything other than round drivers are used. If you're inclined to strive for simplicity, no one should ever be critical of that approach. The sooner you get to hear these, the better.

A while back, I noticed all the interest in the Techtalk forum over Chris Roemer's Nano Neos, and the NTNs. After reading through what has to be the world record length string (35 pages and 693 posts as of this writing), I was intrigued by all the glowing reports, the low build cost, and the enthusiasm of the people who were building them. You can read the string yourself by clicking here.
So, as I've found myself doing more and more, I decided to build a set even though I wasn't exactly sure what I'd end up using them for. They've been done for a while now, and I know you hear this a lot, but they really did exceed my expectations. Even though everything I'd heard about them was highly complimentary, I'd have to say the rave reviews aren't in the least exaggerated.
When I first started on the NTN's I had several other speaker projects going at the same time. That naturally slowed my progress on the NTN's considerably. At that time, I planned to do as others have done -- post any comments I might have about building the NTN's on Chris Roemer's string (the link can be found above). I did make a number of posts, but before too long it occurred to me that what I was writing wasn't likely to be discovered by anyone who is contemplating building the NTN's, at least not without a quite a bit of effort. So, I've decided to create this build string to pass along my NTN experience, in the hope that at least some builders will find it helpful. I'll be copying and pasting some of my earlier posts from Chris' string.
My NTN's will be finished in high-gloss piano-like black. I will also recess the drivers although many have said that there isn't much point in doing that. I figured it couldn't be too difficult and started to scheme about how I'd make a template to use with a router bushing to duplicate the outer shape of the driver. I liked the challenge it presented but it was tougher than I thought -- more about that later. Here's how they turned out:
