Just finished testing a sub I built that I plan to use in a 6th order. It a dual1 15. Fs 37.68 qms 4.74 qes.294 qts .277 vas 4.323cuft mms 266g b/l 20.49 re 1.96 b/l^2/re is 214 an Spl factor of .8 the ebp 136. I haven't modeled it yet but I think it will do well. Opinions from knowledgeable people appreciated.
That low of a qts is going to need massive vent area for a 6th. I foresee the proper vent area being too large to handle unless you're filling the back of a Suburban. A mid-q sub of around .4 to .5 would be a lot better, but honestly (people will disagree) IMO it will be better suited in a ported enclosure.
