Jessie, I do not know why I stuck with the Aura NRT18-8. The Aura NRT18-8 and Aura 1808 are very deferens drivers and I do not think I even mentioned the NRT18-8 as something that worth attention, and particularly in the “Exceptional Drivers” thread....

Thanks, msaudio, for sharing your experience with Aura and Hartley. I do not have Hartleyes. I heard them I think twice but person the people did not try to get out of their playback anything that I care, so it is hard to say anything. In contrary I ...

Paul you are correct about romy's room, my comment was not based for his use in his room. My room at that time was 10X16, and used about 109 db max for that space playing jazz and or classical. In my space the hartleys drivers were the better of the ...

[quote user="jessie.dazzle"]I just ran the calculations again and came up with a figure of 13.8 cu ft (for a QTC favoring transient response, not lowest F3). Then I measured the boxes and they do in fact come out to just under 14 cu ft, once wall thi...

[quote user="jessie.dazzle"] You might be able to get away with a bit less; if I remember correctly, my calculations at the time (based on the above driver) yielded a theoretical ideal volume of something like 23 cubic feet (sealed), so still not...

Back in the 90's i bought a pair of Aura 1808 woofers and made a set of 24 cubic foot corner enclosures 1 1/2 thick, crossover at 100hz, close to 300 pounds, way over built enclosure with a baffle on the face of the enclosure that i could remove. I T...

[quote user="Knightcrawler"]The 1808 in a vented box produces some of the best bass I've ever heard. I know some have a beef with vented enclosures but when designed right the sound can be brilliant. I've heard plenty of sealed, vented, bandpass and ...

Aura made their 1808 driver in 80s and most of the 90s and it was wonderful. It had huge high-temperature neodymium magnet, unique magnet geometry with underhung 4" edgewound aluminum voice coil. It was the only 18-inch...

Let start from the largest drivers and go down. There are larger then 18” drivers (23” and 30”) but looking at this magnet structures I do not find them serious. I addition to make the 23” cone stiff enough requires a lot of diaphragm’s mass or to us...

I was pitching before that to make a loudspeaker with integrated LF module you have no ethical right to charge more then let say $20K retail. If you charge more then you have no mechanism to deliver anything for the money people pay. However, if you...

Hm, the 18mm out of 50mm in “fully in-gap mode” for Aura? It sounds too bad. The last time I touched this subject it was 6 years ago and I remember I had better impression in term of the numbers.
I just looked at the Aura page:

Bud, perhaps it does makes sense to try the “dotizm” one again. I quite severely review my view on the way in wish I use tweeter. I still am trying to make T350 to work, let see what I end up with. Nowadays my T350 sitting in 3rd order crossover, it ...

I completely agree that in a home setting, even if you love "Drum & Bass" and Hip-Hop, you will never ever use anywhere near 2" of cone excursion.
