u have a nice amount of room to play with...i think a 6th order will be good or a low tuned 4th order ... when i get home from work i will post a pic of how it models up

well i just finish playing around with the btl18 that u have and in a 6th order bandpass with 240 total square inches of port it looks like this

the rear chamber is 6 cubes with 80 square inches of port tuned to 34hz and the front chamber is 4 cubes with 160 square inches of por tuned to 70hz
and u can see from the graph it has a 25hz -3db rolloff
