Re: NFS Luna / Duo Follow up
Dave, thanks for your knowledgeable post. Although I have no plans on owning either the Lunas or Duos I always enjoy your technical expertise!
Re: NFS Luna / Duo Follow up
Thorough as always Dave, keeping it simple for us common folk. We appreciate your hard work and also understand it's your passion.
Regards, Bill
Re: NFS Luna / Duo Follow up
+1 on Bill's and Ed's comments (although I currently have the Luna Duo center until my Horizon ships :-) )
Re: NFS Luna / Duo Follow up
Two things stand out to me in this further investigation. As mentioned previously, measuring speakers is not a simple thing to do accurately, and no matter the technology involved, a professional with decades of hands on experience will have a better understanding of how to interpret the results from that technology.
Well done Dave, I think you will help Klippel in understanding the anomalies between measured and derived results, it would appear there is some work left to be done.

Re: NFS Luna / Duo Follow up
Thanks all. This is really an interesting study, well - at least to me ;)
I have spent way too much time and money on this and I don't foresee us recouping the cost of our Klippel NFS purchase (anytime soon). However, from the standpoint of what I do, of what I have been doing since around 1987 or so, it was well worth it.

Not quite sure if I'm hearing a bit of buyer's remorse mixed with rationalization, or if you're actually quite pleased that you now have an absolutely state of the art speaker lab. Maybe a mixture of both. In uncertain times, it probably isn't one's first instinct to make a huge investment in R&D.
In any case, as always, it was a memorable journey, huge props that you are considerate enough to give your customers a glimpse behind the curtain. I can't think of many (any actually) manufacturers that operate at this level of transparency. Thanks for ride along, great stuff!

Dave just think of this (klipple) investment as having that Porsche 918 Spyder in the garage... it's there when you want to take it out for a spin...:)

Sorry, I didn't mean to portray that conclusion - I have no buyers remorse whatsoever.
I am just a little frustrated as to how much time I have spent on this and have yet to come to a final conclusion as to which measurements accurately represent the port response in the far field. I wish I could just let this go but I can't, lol. I need to know for my own curiosity and continued research.
I am thinking a might call in a favor with my friends at SEAS. Send this speaker to Norway and have them measure it in their chamber. They do not have an NFS (few companies do) but they do have a true anechoic chamber and use Klippel gear for their measurements, so this would be an appropriate comparison. The results of those measurements would give me my answer.
It's a real pity that here in the states, gaining access to a chamber - even for scientific purposes - is nearly impossible.
Re: NFS Luna / Duo Follow up
+1 for me on Duo v2 availability list! (long term Sierra v2 owner, recently picked up 4 HTM-200SEs for surrounds for new basement HT setup)
This has been quite a ride. I've been saddened by the cynicism about the measurements, awed and inspired by Dave's reactions in word and deed.
It amazes me in these kind of niche "hobbyist" markets (my other personal one being hobby boardgames) when people's first thoughts jump to cynical assumptions when something isn't quite right. The people working in this kind of industry (especially at Dave's scale) are so clearly driven by the love of the thing and could be making more money for the same or less effort doing something else.
Thanks for all the dedication and, as others have said, the transparency - it's fascinating to have a window into all of this.
