Focal 33K subwoofer enclosure
 

I found a great deal locally on Kijiji (30$) and had to get it. I tried to email Focal to get enclosure specs without any luck. Looking to build a sealed or ported box, haven't decided yet.
Any info would be great, thanks.

Focal 33k doesn't need sealed box because mms and qts are very low. you can use 50 liter box @35_40 hertz it depends on what song are you listening to?

35-40 hertz is enough for any kind of music that he's listening.
