thats fair enough thanks for the replyI 'd advise steering clear of two usual questions.
First, you're tuned a major 3rd below low B: Leave that to the house system. It's a fool's errand trying to make a stage rig to push fundamentals in the low 20hz range, not to mention the bleed into every mic on stage. What we hear as bass is actually in the 100-200 hz range which is routinely handled by most any commercial cabinets.
Second, as @JimChjones points out, commercial bass guitar bins are all designed as standalone cabinets, which regardless of format, are designed to operate in the same frequency ranges, unlike 2, 3, or even 4-way commercial FOH cabinets which are designed to work together.
IF you find that none of the bass bins you audition aren't right for you, you might want to consider a 2 or 3-way PA bin, with the proviso that it may be almost disturbingly clean vs. bass cabinets (and all the dirty work is done vs. building something similar on your own).
You and your ears will have to decide.

honestly in a years time when im ready to push my rig to the next level this might just be the answer for me or is at least worth spending some money to try it out and see if i like it.
