Let's hope it doesn't have foam surrounds. I've dealt with some of the older Audax paper cones with foam surrounds and they've all perished.

This is an old stock built in 2003... 15 buck at my local store :santa3:
One of the best built 2" driver i ever seen... 1Kg of metal, paper, copper, glues and butyl surrounds slighly damped with low visosity gel !

Surprised nobody has mentioned the Vifa/Peerless/Tymphany TC9FD18-08 or better yet, TG9FD10-08. I would try these first due to low cost, very low midrange distortion, very smooth frequency response and quite decent off-axis performance.

The distortion down at 100Hz is not the best you'll find, however. Attached is the graph for the TC9. The TG9 should be better. Of course, I haven't heard a 3" driver that has truly clean bass.. others in this thread may be better in that respect.

Resonnance should be under 100Hz, and the VAS is a bit high for a small enclosures.

yes, we are familiar with the Vifa - given a option of anything but a Fostex or Alpair in this size range, I'd take the ScanSpeak 10F

Resonnance should be under 100Hz, i don't knnow why the CSD don't show frequencies under 200Hz !

dh sat

Hello,
i made a new construction a
double horn satellit, with 2 x 3" driver,
high dynamic, superb soundstage, deepness,
working best with only 100µF and sub 100 Hz 18 dB.

the point is you can´t get 100 Hz with a driver with only 0,35 mm stroke,
if you want go down 100 Hz a 3" need more than 1mm stroke even in a horn.

may be my single driver sat horn FLUTEis a solution, it is my smallest.

If you can find a pair, the Bandor 50 is The best small FR I've heard, period. And the design is 20 yrs old at least.

What about Aura NS3 or the Dayton ND90 or 91?

I've considered them but finally... go to my local store because of an Audax sale.
I'm a little bit scared by the mecanic and aerodynamic noises of such very, very long excursion drivers like the Aura.

The Bandor site is up but the lady who produces these drivers must be in her 70s now. I doubt they are in production at this time. I did see them on a European site recently, old stock. Buy them at whatever they are being sold at, they are that good. The shallow cone profile and anodising predates Mark audio by two decades, they are works of art

If 4" are ok, tangband w4-1320si. Why ? CSD looks good even in high range (i've seen this measured somewhere on diyaudio too). It seems that the neo version only got a so well waterfall in high range (inductance stuff effect?).

But the 10F of course is awesome...i wonder how thd compae in low range (high excursion) at same level as a 4" like the tangband...(?)
The tb is for example 50% bigger cone (sd), so need less excursion. On the other hand, it does not have voicecoil back vent... Another aspect is that a 4" is more directive (should be a good or a bad thing depending on where it will be used).
[i measured the tb effective SD without phase plug and got +/- the same as specified around 54cm2]

Put it this way, if you move your head around, you won't notice a sudden treble disappearance act. Some ring radiator tweets are probably worse, 15 deg off axis

The Seas T25CF002 Millennium of my main speaker have the same problem, i've dedicated them to the TV because of the directional pattern (I must remember to turn it on one day...i've never tune the channels and i don't know it works😕 since 4 years)

You must stay at the sweet spot (your chair) and don't make a move... you can also hand your hands up (and give your money😀)
