I came across this paper earlier - http://vbn.aau.dk/en/publications/l...rs(2961def0-3b73-11dc-b148-000ea68e967b).html - and, in particular, paper D inside there which is "Controlled Acoustically Bass System (CABS), A method to achieve uniform sound field distribution at low frequencies in rectangular rooms"
This is an approach that was implemented in a few places, physical devices I've come across are the the Klein & Hummel ARAM (www.klein-hummel.com/klein-hummel/globals.nsf/resources/o800_o800aram_studio2005_e.pdf/$File/o800_o800aram_studio2005_e.pdf) and the bagend etrap. In software, it has been implemented in Ultimate Equaliser (http://www.bodziosoftware.com.au/) & it also seems to be the same thing as a VBA (virtual bass array) in acourate.
I have a spare sub atm so thought I might try it out to attempt to dial out my 1st axial length mode (which is quite a big peak to say the least). I was just curious to know if anyone has tried this before, i.e. not a full DBA/SBA but just a tuned bass trap where the trap is a subwoofer. It seems like it will be prone to total failure but could be interesting to try.
