You're right, tinitus. I heard that Zaph wanted to measure one of them, but somehow the AE didn't like Zaph's testing conditions. But I'd use one of them even without see Zaph or Mark's distortion measurements. They are unique in some important aspects.

Perhaps asking them would be the best course of action. I haven't looked through their forum either but perhaps they have posted some information there that isn't available on the main webpage.
As said, surely very nice drivers
if I could buy them here at US prices I would definately buy them, and mostly because they seem to have good specs fore home use, unlike many other pro drivers
I want to buy well designed and solidly built drivers, not farraday rings, fancy looks or other empty mombojumbo marketing hype...but I am close to falling in, waiting fore the new AE midrange

tinitus,
I suggest you take AE data to MJK's worksheet and simulate,
that will give you a good view of AE units frequency response.
That is if figures are correct, and they probably are as such figures are very easy to measure.

I take it you mean bass response, I have been through all of them 😉 Have decided on a Faital 18" in closed(almost), looks like true work of art 😀 but still searching fore a mid, maybe 18Sound 10NDA610 with AIC coil(active impedance control), completely flat impedance to 10khz 😎 but its expencive
About the AE drivers...I wonder whether the drivers shown are with single farraday ring or with "the full monty", or if the rest have to be ordered special, at a cost...its not completely clear😕

Thanks Jay 🙂 My intention is to go all sealed, so I think TD1*S is the way to go? I have a sub for <80hz if need be. Any reason to choose 6nd430-8 over 6nd430-4? My planned amps - hypex - are rated for 4 ohm loads. (active pc crossover)
🙂
I'll have to have a look at the Faital drivers.
The AE drivers do have an upgrade option, I wonder if this is required for the good performance - it's a significant price jump.
Back to 6ND430, finally .... it seems to be OK down to 80hz in closed, with -6db where you have your XO point, in BR its 60hz
with 10mm p-p Xmax it should do OK fore normal listening, when you have a sub up to around 80hz
Fore simplicity double 6ND430 in a 2.5way could be the way
If loud rock&roll, just ignore
btw, there seems to no mention of any short rings fore this driver? seems there are other ways to clean sound with low distortion and flat impedance? 😕
About foam surround, I know its good fore the sound, but I really dont feel confident about them

"Amp output level was adjusted for each driver so that the fundamental was 92dB at 1/2 meter. The level was set between the range of 300-1000Hz."
I missed that important part.

I thought you would do BR without a sub. The 8 ohm version may reach the SS6600's sensitivity.
With this driver combination, I'd place crossovers at 200-400 Hz and 1.75-2.0 kHz.
Jay_WJ said:
🙂 Hmmmm..... I'm trying to avoid group delay in the low frequencies - my sub is a Rythmik Servo 12" sealed. I know it won't quite keep up with the rest of the system but by that stage it'll be too loud anyway and I'll have the 3ways out on the lawn. 😎
The 4 ohm 6nd430 is listed at the same sensitivity as the 8
Cheers 🙂
fb said:
Having such fine sub I think any of the AE will do just fine in closed, even the M series
You will have a dream setup 😉
fb said:The 4 ohm 6nd430 is listed at the same sensitivity as the 8
Really? It can't be. If so, no reason to use the 4 ohm version. . .

🙂 Thankyou

See post 4 of this thread for the specs 18sound emailed me. I want to use all 4 ohm drivers as the Hypex class D amps I plan to use are designed for 4 ohm use, and I'll be active amping/ pc crossover.
fb said:
Are you sure that it's sensitivity, not efficiency? I don't believe that a 16 ohm version is as sensitive as a 4 ohm version. If your amp can drive 4 ohm drivers, no reason for it not to drive 8 ohm drivers. Assuming every other factor is the same, there's no reason to use a 4 ohm driver when there's as sensitive a 8 ohm driver available. Only reason to use a 4 ohm driver is to take advantage of its higher sensitivity at the expense of higher input current.
Jay_WJ said:
I suppose it depends on the overall design...BL factor and induction seems to be the parameter that changes the most
Of course, in theory we can make a 4 ohm driver no more sensitive than its higher impedance version. But in practice I don't see any reason to do so.
6nd430-16 ohm
Hi,
I've got four of these drivers waiting to be boxed. I got them to replace dynaudio 17w75xl-12s in my old system. The only drawback so far is that the guy from US speakers overcharged me for $100 in shipment charges. It was to cost $125 for four drivers to be shipped to Australia (actual cost on the box $97) but I was charged $225. That latter figure comes up automatically but I complained about it and Al ensured me that the shipment and handling will cost only $125 but billed my card for one hundred more. And of course does not respond to mails. Anyway, back to the drivers.
The reason for replacement was sensitivity mismatch between my midrange (Audax hm-130co) and tweeter (Exotec-260). Paralleling two dynaudios was to give sensitivity over 90dB at 1m at 2.83V. In reality dyanudios measured 85-86dB below 500Hz so sensitivity wise I had to "downgrade" the rest of the system. It was not a problem as my system is active.
After many years I decided to get even and match dynaudios with peerrless midrange of similar sensitivity to work in my home theatre and get more sensitive drivers for my main hifi system. I did not have much choice here - either 6nd430-16 ohm or phl drivers. I chose 6nd430 just looking at specs and simulation results for two 6nd430-16s..
Within a week or so I'll know how it all sounds. Dynaudios also have not so good frequencies below 100Hz but that does not bother me much as below 100Hz the subwoofers are going to take over. I intend to use Rythmik Audio 15" servos but I'm still waiting hoping that Rythmik will come up with better 15" with 75-100mm voice coil, a few more mm of linear extension and low distortion - say comparable to velodyne - above 40-50Hz.
cheers,

I have my 6nd430s boxed. They still require final fine tuning including vertical alignment of accustic centres but at least the system is operational.
My impressions after a couple of weeks of listenning are prety positive. Just in direct comparison to dynaudio's w17-75xl-12s they replaced eighteensound drivers, apart from being louder due to their higher efficiency, seem to be somewhat more detailed and accurate. They may also be driven somewhat harder than dynaudio's. On the negative side 6nd530s are somewhat weaker in the lowest frequency department.
All the above are just subjective impressions not supported by any direct measurements. I'll do some spl tests in the near future after a few more weeks of driving them. This is about all I can do as I do not have other speaker realted test equipment.

Cool.... vented?
The Rythmik subs are yummy, talk to them (if you haven't already) to see if they have any future plans.
For other Australians interested in this driver, these are available locally from info_at_atprofessional.com.au
They're in Brisbane, I was quoted $230 RRP - 30% per driver.
