Can one of you tech types run the numbers on the above and compare it to a Gauss 3184B?
Here are the Thiels for the Gauss
FS=37
QTS=0.1476
QMS=1.9
QES=0.16
Vas=30
Pe=150
Xmax=1.6
Re=6
Le=1.3
Sd=0.01415
Bl=36.006
Mms=148.71
Thanks
Ken

Hey, Ken...
What is diam? 0.254 m (10-in) like the 3184A?
What are units on Vas?
What are units on the Xmax?
What are units on Sd?

"Indeed, not!!"

They are 10in drivers
Vas,Xmax,Sd for the gauss are listed in prev message. Do you want the Thieles for the 2123H?
Ken
OK on the 10in.
You gave quantities, but I need the units - either Imperial (in and in3) or Metric (m and l).
Thanks.

Never mind - I found them in BBPro. But, there are some differences with those you posted. Here's what BBPro loads:
Fs = 33 Hz
Qts = 0.14 (dimensionless)
Qms = 1.9 (dimensionless)
Qes = 0.16 (dimensionless)
Vas = 31.15 liters
Pe = 150 watts
Xmax = 1.6 mm
Re = 6 ohms
Le = 1.3 mH
Sd = 346 sq. cm

Here's what WinISD produces. I printed it to a .pdf to retain the best resolution.
To my eyes, there will be no discernable audible difference between the Gauss 3184B and the 2123H. The Gauss 3184A, however, has sustained low-end, hitting -3 dB at 150 Hz. I don't know if that is or is not desireable, depending upon where you cross from the VLF (2235H?).

Yes, I am going to try the 2123H's in my Westlakes.
Will let you know how they sound.
Thanks for the help
Ken
Here's comparing the Gauss 3184B to the 2123H from BassBoxPro. Also in .pdf...

I think the Gauss driver is more along the lines of the 2122H. Do you feel like running that one Bo?
I am not very good at understanding these plots but this does confirm why the amp driving the 3184B's runs so hot. The load is slightly over 2 ohms.
If you don't mind that would be great Bo.Originally posted by Giskard

Here's the 3184B vs the 2122H (both 1997 and the 2001 vintages).Originally posted by Ken Pachkowsky

But I'm not certain these graphs "confirm" why your amp is running "hot" - maybe Giskard has more experience in this, than I do...

Ken,
If you are looking for alternatives the Tad 11 inch carbon fibre composite is excellent and also the PHL hi sensitivity 10 inch mid cone, also the 2118, even paired is excellent and it can run down to 70- 100 hertz

Well, I must admit we had a difficult time picking the best sounding driver.
Both drivers sounded quite different. The 2123H sounded slightly cleaner and more dynamic when played on its own (all other drivers turned off and a-b ing mono source from left to right etc.)
My wife and I felt that in this initial trial the Gauss 3184 sounded slightly better over all. I have put the 3184 Gauss driver back in for now and will experiment more later.
Ken
The photo in the previous post is awfull. The flash on my digital camera sucks. The driver was baffle mounted on the plywood and then the plywood was bolted through the existing ma15 bolt holes. Here is a closeup of the Gauss 3184.

I have added the 2123 to my s7. It sounded real good in the .6 closed box, but when I added it to the existing speakers it never sounded quite right. I experimented with different crossover frequencys to no avail. Then the schematic of the 4344mkii was posted here (http://www.audioheritage.org/vbullet...=&threadid=751). I tried adding the coil and resister to the mix just before the 2123 terminals as shown in the schematic.. I was amazed at how much difference it made. Since I was using the J model I used a 12.4 resistor. Am now crossing 350 hz. Hope this helps.
