Vifa M17MH 7" paper midrange drivers

Not open for further replies.
These are a 7" paper mid Madisound had on sale a while back. I didn't think to copy the spec page they had but the FR graph was pretty smooth up to about 5k where it peaked a little before dropping off. The T/S specs are:

Vas 36.250
Qts 0.260
Qes 0.310
fs 45.3
Xmax 2.00
Dia. 13.00
PEMax 25

Sensitivity is 92dB/W/m, impedance is 4 ohms.

Sale price was $18.50 each, I'll sell 'em four at a time for $50 including shipping in con US (I have 8). Thanks!
