ok....i WAS going to pay someone to do this for me but i realized i can do it myself with the basic accelorator-pedal.com thing and i have a few designs...

ihad about 6.5 cubs tuned to 35Hz and i liked it, it was a great SQL mix and im going for something close to that. that SQ was good but could be just a small hair better..... so i was thinking aboutlower the tuning... but here's something ive come up with

6cubs tuned to 35Hz, 101.75in^2 port area, 29inches of port length -likebefore

4 cubs tuned to 32Hz, 97.125in^2 port area, 55.75 inches or port length - little bit lower tuneing, possibly better SQ but im unsure about the ideal internal volume for that tune, should it be increased or decreased?

4 cubs tuned tp 28Hz, 83.25in^2 port area, 64inches of port length. - i've heard many good things about this design and it's flatter curve in terms of frequency response and it haveing amazing SQ....how much SPL would be lost though? i dont want to sacrific much SPL so would this might be tuned to low.

im leaning towards the 32Hz tuned box, but for a 50/50 SPL/SQ mix what should the internal volume be?

any thoughts or other box designs you'd like to add feel free
