I'm using SVT cabs. Tried the 610, but that one had a ported cab and was a little too boomy for me. Can't fit the 810 in my car, so I went this route instead - a 410, and a 210 (both sealed enclosure).
There are probably better cabs out there, but I got these used and cheep
, and they sound decent with the Orange
I wouldn't mind trying one of those Berg NV610s someday.
