My partner built and tested these subs, and they sound great, and he has only been running 1 at a time in a 2cf sealed box inverted.
The specs show they would do great in a 6cf box and larger.
Dual 2 tested at 3.98 ohms in series
Fs is 19.5hz
Qts 0.164
Qes 0.166
Qms 12.75
Bl 50.06
VAS 10.45cf
Le 5.5mH
93db efficiency 1w 1meter
18mm 1 way linear capable to push some series air
copper coil 21gauge wire 4 layer
800rms easily
No longer for sale
They weigh around 50 pounds each.
