I have been reorganizing and modularizing my gig rig. Selling off some cabs and buying a 2nd AVATAR 2-10 cab. As I can lift them by myself (two back surgeries last year means my SVT 8-10 cab is NOT leaving the studio!) Has anyone noticed any difference in bass performance - If they face multiple small stacked cabs with the vents co-joined - or - at ends ? Or just ignoring that and simply stacking ? Since these cabs have the vents that are a long slot along the bottom of the cab, you can have them with one upside down and the vents working together, or a vent top and a vent bottom by flipping one.
