I am in the middle of building a small vintage rig influenced by King Tubby's Hometown Hi Fi, Tom the Great Sebastian, Tip-A-Tone etc.

I have two side boxes for the mid/tops and a centre reflex fo sub. For some reason I am really struggling to find the ideal cut off frequency for the XB that's installed. The best sounding so far is 35hz 18bw slope but seeing if anyone has any suggestions. 

I am trying to find an all round sound as we do play everything from early ska, Rocksteady to real heavy Steppas type stuff and the plan it to EQ as we go along. 

Any suggestions?

XB probably isn't the one, a studio or b might be better

Unfortunately it's what I have to work with. It's only a small bar system anyway so sub levels will be pretty low, just need to work out what's best.

The XB will be fine. If you are not pushing things then go with what ever sounds best. If you know the tuning of the box or can measure impedance to find this then you can avoid issues at high power, but for background use I would not worry.

Thanks, due to the port size it is tuned to about 33hz, but it does have wadding in so that could be making a difference.

I think what the thing is that my previous systems were more ska, northern soul, early disco so I'm used to tuning more mid style music. Obviously I am playing with much lower frequencies this time, so want to make sure I am in the right ball park and not cutting off to early/late. It might sound strange but it does sometimes sound a bit too subby.

Northern soul has loads of bottom end.
