Yes I did and I have no objection to any comments or comparisons.
Well, there is a Note II sitting in my room. It is unlikely that anyone else will hear it unless they choose to build there own. I'm not inclined to go to audio shows to demo my speakers. I don't have any interest in that. It's noting but hype, spin and spam. I'm not part of the audio main stream and have no aspirations to be so. Speaker building is not so much a passion for me but a diversion from the winter. That is why the Note II has been in arrested development since last spring. Frankly, and I think I mentioned this before, it probably would have remained so had SL not introduced the LX521. But with that introduction I wasn't going to sit on my hands for another 3 to 6 mounts and have the usual suspects start making accusations of copying SL's design. No, the Note came first and the revision has been in the works almost since the introduction of the Note, 2 years ago. It amazes me how similar the Note II and the LX521 are since they were developed independently. SL's baffle may be considered to exhibit a more "artistic" flare while the Note II obviously follows the path laid down in the original Note. Along the path SL may have zigged where I sagged, but that is what makes things interesting.
Would it make sense for him to explain why his designs are not as good as SL's? No, of course not. So as long as he makes valid points, there's no problem, is there? People are then free to decide which design they prefer.
Thanks. Definitely looks very good, my Neo3W still had some slight blooming around 7 kHz (which was worse with the PDR, by the way). Is the 6 kHz crossover in your design critical to prevent this? In other words, would there be blooming with a lower crossover?
I'm wondering, the slight bump off-axis, around 2 kHz, is this caused by diffraction? Or is this caused by the fact that a driver is no longer an acoustically small dipole?
I'm looking at a lower crossover point. The wave guide should keep the tweeter behaving correctly to lower frequency. Not sure about the 2k bump. I was not as significant in the original Note. I could be a result of the RS like side pieces.It needs further investigation.
Actually if you look back JohnK had always been the pioneer eg. Rear tweeter, variable baffle width. Linkwitzlab, though provided very nice and unique aesthetics like the Orions, Beethovens, etc.
For the latest iterations that is the variable baffle width, I am not a fan of both Nao Note and LX521 in terms of looks!
The dipoles at this point, I think, has been done to death (?)... let's see another approach 😎
Everything has been done to death 🙂
How about 2nd order gradients.
Let's try that with CD up to 20kHz!

It could be possible I guess?
We could use a shotgun type of horn at the top. Like "Living Voice's-Olympian"

The problem with that is content:
Could you point me to a good multi-channel recording of “Figaro” with Cecilia Bartoli singing Cherubino?
He's not talking about multichannel, although his wording is off.
He is saying classic stereophonics is dead.
It's not dead, but it should be....in audiophile listening sessions 🙂
Edit: IMO 😉

DPL2 does a great job of expanding 2-channel sources into multichannel.
Though not as well, admittedly, if one's center is not identical to the left and right.
Looked at tweeter polar response this morning. I looks as if the tweeter x-o could be reduced to 4.5K while maintaining -3dB at 45 degrees, -6dB at 60 degrees, consistent with dipole radiation.
Just a shout out here. I live in CT about 30 miles from the shoreline. I did not have any damage from the storm but I did lost power and cable until yesterday. So I am just catching up on the news from NY and NJ. I grew up in Philly, Pa and spent many, many days at the Jersey shores from Cape May in the south to Point Pleasant in the north. Most of that area has been devastated by Sandy, as has been much of the cost of CT. And of course, the news has focused on NY.
Please take a moment and realize that all this speaker stuff and the banter back and fourth really plays little roll in our lives. My thoughts and prayers are with all the people affected by this continuing disaster. It will take years to recover and these places and the lives of those who live there will never be the same.

About the 2k bump. Please recognize that in the waterfall plot the response at each off axis location is normalized by the axial response. If you look at the axial response plot you will note a dip in the axial response at about 2k. Off axis this dip tends to smooth out somewhat with the result that the bump in the waterfall is somewhat exaggerated.
I've posted some updates. After experimenting with the system I decided to keep the tweeter x-o at 6k. I have changed the woofer system to an N frame dipole (this was an option in the original Note) and I will go with the SLS 10" woofers. XXLS woofer would increase the max SPL by only about 3dB and if greater max SPL and extended bass is desired it makes more sense to spend the additional money of one or two powered subs rather than on the XXLS woofer.
... or you can always try and shoehorn two SLS 12's. More Sd, more efficient, lower Fs, only extra 20 bucks. Would easily cover missing 3dB, and more.
Great design!
As always, I must add...
