Orion vs Abbey - Page 5

LOL, I had forgotten about that. ROTFL.

I'll be at RMAF. Perhaps if you're going as well, we can meet up and you can show me how much a transmission line speaker possesses Helmholtz resonance by blowing across the terminus vent hole.....

That's funny, I don't remember ever saying anything about a TL with a Helmholtz resonance.

How would exciting the resonance at the terminus indicate what the resonance mechanism is?

AJinFLA....Damn dude, you have been here a long time but you never post. It always reminds me how many members from other forums lurk elsewhere.

What we need is one overall site engine that combines all threads forums....one big DIY sharing website

I like it.

The Nao Note seems to be complete last time I looked. Pricing is on the products page.

I thought he was now working on the Nao Note II so the Nao Note has been out for a bit. John K posts on DIYAudio.com all the time so you can just ask in the multi-speaker forum.

The nao note was just released this month. There is a nao note II already? The polar measurements for the Note look great. I'd love to hear it.

I don't post here but came upon this message and wanted to clear things up. The NaO Note was released October 1, 2010. There are no updates or a "II" version. I do not anticipate any changes in the immediate future unless feedback from builders indicates a consistent area where improvement could be made.

There were some earlier "preview" web pages that I failed to delete from my site. They were of the preliminary design efforts. The released version of the Note is documented on the current pages of my site.

I hope this clears things up.

John k....

Thanks John for signing up and clarifying everything. My confusion comes from the NAO II link on your site but that is not the Nao Note.

Sorry for any confusion on this topic.

For everyone else here is John K's site

Great info and links on this page....lots of topics that will make your head spin over speaker building.

So far I have sold plan sets to builders in Europe and Australia. None have been completed. Plans have only been available for 3 weeks though. I don't really promote my stuff. It's just a hobby and I happy to share wnat I do and cover my development cost.

The only completed system to date (and Lord knows I'll be tinkering with it to try and make it better) is the one in my home in Connecticut. I'll be at the NE DIY event with it this weekend.

All the pretty polar pictures are nice to look at but knowing and having worked with the tweeter you've selected over several years, I think it would be a lot more beneficial to those considering building this design if you posted information about the limited vertical window in which high frequency tonal balance will be maintained. The tweeter chosen, although superb in many respects, was primarily intended for line array use and has very limited vertical dispersion. Unlike the Orion's SEAS Millenium Excel, there will most definitely be a significant difference in tonal balance from sitting to standing position. If you haven't built an adjustment into the base of the enclosure to produce some tilting, perhaps it should be considered.

Not sure why. My most recent build has some design cues from Wilson's Alexandria but incorporates tilting adjustment at the speaker's base instead of up above. If using a planar driver like the NEO 3 solo, it makes sense to put adjustability somewhere, whether tilting the entire speaker or a subset of the drivers to maintain the desired geometry.

If I'm reading you correctly, tilting for listening while standing is likely to compromise seated listening and tilting for seated listening is likely to compromise listening while standing - unless you have Napoleon's physical stature. A small array would be a better approach with this driver in terms of reduced distortion, dynamics, bandwidth, and dispersion. But that would require a little more design ingenuity, testing, and enclosure construction skills.

I've owned and listened to Gedlee Summas for close to half a decade. Some thoughts:

1) I don't think they sound much like dipoles. Dipoles tend to exhibit a lot of 'bloom'. They have a 'spacious' sound. I think a lot of this is due to reflections off of the back wall.
2) I'm definitely a fan of dipole designs. Actually found this thread while trying to find someone who'd compared the Kreskovsky or Linkwitz kits to the Geddes kits. I've heard the Vanderstien and Alon dipoles.
3) While people tend to fixate on the waveguide of the Geddes speakers, I'd argue that the midbass and the imaging are possibly it's strongest suit. That 15TBX100 is a heck of a driver. I wish the speaker was smaller, but I cannot deny that the dynamics are to die for.
