I think new plans for the NFX is a great idea.  I managed the build from the old plans but I had to do a lot of extra figuring to get the correct dimensions and angles for cuts.  Anyway, the NFX is a very fun build, and not too challenging if you take your time and label your parts.  Think before you cut and double or triple check to make sure you are on the right part and the right angle for the cut.  I suppose the new plans will make this part easier.  

My NIbbelins are truly awesome speakers that easily outperformed my Klipsch RF-7s.  So much so that I let one of my kids take the Klipsch away.  I encourage anyone out there to build these great speakers.  I listen to a lot of FM classicial and jazz nowadays.  Right now the guitar player doing a lute suite sounds like he is right here in the room with me.  Oh yeah, the 96db Steve says on the site seems a conservative value to me.  The DFR-8s are detailed and musical at the same time.  From those that have heard them the response is simply a jaw-droppin, "WOW".
