John which one are you using for your project, The c173n-t6-90 ot the c173n-t6-96? Im confused..

Comparison sheet – new and old model numbers – September 2006
New system:
1. letter indicates cone material; D=diamond, C=ceramic, BD=black diamond,
BC=black ceramic
2. number indicates – a) basket outer diameter for round baskets and b) membrane
diameter for square baskets
3. letter indicates Magnet material (only present if other than ferrite); N=neodymium,
A=alnico
4. letter indicates voice coil former material (only present if other than aluminum);
T=titanium, K=kapton, P=paper
5. number indicates DC resistance
6. last number identifies production data sheet and is a unique and exclusive
identification number for each model. Whenever possible, we used the previous
number for easy remembering, for example #95 for the successor of C295-T6 or
#23 for C223-6
Example:
C173N-T6-96
1. 2. 3. 4. 5. 6.
So this is a 1. ceramic bass-midrange with 2. a new 173mm basket, and 3. a neodymium magnet system. It
has a 4. titanium voice coil former with 5. six Ohm voice coil. 6. production data sheet number is #96.
Example:
C25-6-12
1. 2.(3)(4)5. 6.
So this is a 1. ceramic tweeter with 2. a 25mm membrane. 3. the missing letter indicates standard ferrite
magnet system. 4. the missing letter indicates standard aluminum voice coil former with 5. a six Ohm voice
coil. Production data sheet number is #12, reminding of the former name C212-6 unit to which this unit is
identical.

Nice explanation Jed.

Nice explanation Jed.

It's just a cut and paste from an accuton document I found, but it definitely should clear things up from now on.

[tyler]

Jed, have you seen the C173N-T6-96? I think it is replacing the C173N-T6-90. Accuton removed the C173N-T6-90 from there website. I am glad I already have a pair of those they are really getting hard to find.

The C173N-T6-90 is the one I'm using- it's still listed on Madiound's site, which would lead me to think it's still available. Notice how the spec'd Fs is much lower on the -96; doesn't make a lot of sense for the midrange.

I have never seen them supply the C90 info on the Accuton web site.

I'm pretty sure Accuton is still making the C173N-T6-90, as Selah Audio got a shipment of them not too long ago. Madisound doesn't have them in stock however, even after recently receiving a shipment of C79s. Accuton has REALLY long lead times.

[TacoD]

I think the 96 is the midbass and the 90 is the true mid. Both still availalbe at the dutch importer.

[Beau]

That what confused me, the FS difference mainly. Wonder hoe the 96 would go in a 2 way...

I would think Accuton is doing something special for them considering the range ~30Hz-100kHz.

[TacoD]

Kharma works closely with Accuton, Kharma was the first highend manufacturer using Thiel & Partner (that's the German name of Accuton). Also the laser cut dampening is an idea from Kharma (according to the production chef of Kharma I talked to).

I don't think 30 Hz is realistic, 100 kHz is the diamond dome so nothing new there.

I don't either, that's pretty low for the C90. However, those are the specs listed on there website.....

They use something like 96, Fs = 37 Hz.

I have one driver and it was the last one available via U.S. distributors. Accuton is selling drivers faster than they can make them and their delivery times are several months. In the food chain the larger manufacturers (Kharma,etc) get drivers first and distributors are given the lowest priority. I purchased most of the C82's from the last shipment to the U.S. and cannot get a ship date for the drivers I have on backorder.

accuton crap

This driver is unspeakable garbage.

[Jed]

Hi guys,

I just found some new information about C173N-T6-90 and it seem there are several improvments in this driver:

http://www.clofis.nl/nl/thiel/C173N-T6-90.pdf

The mechanical suspension is much more harder - Qms 2.908 vs. 6.54 compared with the old version of the driver, but surprisingly the resonance frequency is lowered which enable us crossing it under 240Hz.

I don't know which version Madisound sells, but I'm tempted to order this midrange. It seems to be the last midrange driver I will ever buy

Hi and welcome to the forum. These Accutons are hard to come by- out of stock in the US and some venders have had orders since last January.
