Vifa TG9FD10-04 3.5" Full Range
At $9 a pop, this is a pretty sweet deal. That FR looks really smooth, copper cap on pole piece. All for $9. Happy Holidays!

seems like it would have about the same thermal power handling as other variants - - will cheap HT receivers drive ~4 ohm loads long term?
And I've seen a car audio review where the guy really liked the tc9 paper cone better.
The tg9 has a bit of ring in the last octave.
Fiberglass scratchiness i assume from the glass fibers rubbing.
I had a mtm with fiberglass cones but it was crossing maybe 4khz, not sure.
My w4 1337sdf rang at similar to the tg9.
With 10 band eq, i noticed i boosted a little at 8khz and zero at 16khz slider, unlike my normal smiley faced 10 band eq settings. But 40 plus old ears probably can be more tolerant of this than sharper younger ears, or female.

The TG9 8ohms is actually very good. I like the sound a lot - almost as good as a $100 ScanSpeak 10F (also fiberglass).
I am not sure what they did with the 4ohms version but it seems to have very different measurements.
I tested it here and people also listened to it (it is Driver "D"):

It measured quite well (in FR it measured almost identically to the 10F):

Other prob is one cant connect a pair of these in parallel, the only connecting possible are serie which is a drawback sonically.

Yup, at $9 a pop, it comes into the TC9 territory for price. Line arrays become an option. I did get my TC9s at even cheaper than that as a bulk order at PE. Might be worth asking at Madi about bulk pricing on the TG9 if someone is investigating drivers for a line array.
I was thinking the 4ohm version would be great for use as a pair per side, wired in series, in either a bipole or 1.5-way configuration.
Is it my imagination, or is the FR graph of the 4ohm version cut off a lot earlier in the HF? It is listed as 10kHz on Madisound - a high reaching mid-range?
4ohms could be tough to drive with a HP amp unless you have a speaker amp or maybe a SE Class A room heater like I do. 😀 Although, being only mm away from your ear, not much power will be needed.
That was an adventure XRK. Looking back at that frequency chart really shows the Vifa and SS stand out compared to the others - each of which probably can be considered more of an acquired taste than an accurate driver.
