Hello to all!
Please tell who met the project for dynamics Scan-Speak 18w/8531g00e the closed case?! And in general it is real for it?!
Thanks!

I use my 18W\8531G00's in a 25L sealed box, they roll off at around 60Hz. I use a 2nd order high pass filter on them at 60Hz and a 4th order linkwitz-riley lowpass at 60Hz on my sub.
Here are recommendations from some loudspeaker companies:
Akustyk: 14 litres Qtc 0,71 44 Hz -6dB
Eltek: 18 litres 53 Hz - 3 dB
Strassacker: 16 litres 57 Hz - 3 dB/ 36 Hz - 8 dB
Akustyk: 14 litres Qtc 0,71 44 Hz -6dB
Eltek: 18 litres 53 Hz - 3 dB
Strassacker: 16 litres 57 Hz - 3 dB/ 36 Hz - 8 dB
2 gfiandy How many litres should be the close enclosure for this dynamics?!
2 FullThrottleRic - And it is possible, what it would play from 47 Hz? Or for this case it is not possible?! (
P.S. Sorry, me English is NOT well!(

Those figures seem out to me, as far as I know the driver hasn't changed since it was introduced.
For me (using WinISD) 14L gives Qtc of 0.809, 16L 0.772 and 18L 0.742, all have f3 roundabout 58-60Hz.
To get f3 down you will need to use a vented box (which the driver is intended for really), QB3 would be 38L tuning to 30Hz with f3 around 32Hz.
