pig in a poke Nirvana T-S parameters - where do Super 8's run?

freddi · 02:34 AM

grabbed a stamped pair from auction - seller didn't measure - where are Super 8's running for Fs, Qts and Vas? My super10's Qts ~0.42, Fs~49 - hope Super 8's qts comes in below 0.38

have AN users compiled listings of parameters?

Then let us hope for once they come out vaguely near what AN claim.

LOL - - my used pair of Super8 look real good and qughta rock in certain K-couplers plus should be ~interchangeable with FE206 in blh application

Vas?

dunno the location of my scale - if published mms=11.663g and real Fs = ~49 vs 37.4, can you guesstimate Vas? (I believe the seller said they've been run-in >500Hr)

Averaging what you have:

48.45 Hz Fs
2.922 Qms
0.26 Qes
0.238 Qts
7.434 ohms Re
0.128 mH Le

Published:

11.663 g Mms
8.8 cm radius = 243.285 cm^2 Sd

Calculated average:

Vas = 78.604 L
BL = 10.0755 N/A
Cms = 0.00092521 mm/N

that's a decent BL compared to W8-1772 - fwiw FE206EN lists pretty close - my FE206EN qts also runs higher than spec according to WT3
