i'm almost certain then that i'll build a 3pi something like this.
eminence lense, de250 and delta 12lfa.
i'm probably going to shoot for a 4 cubic foot enclosure and tune to either 40hz or 35hz.
according to winisd that will give f3 around 45hz and the gain starts rising just a bit around 200hz so that might help just a bit with BSC if i want to pull the speakers out from the walls. i think it only rises 2db at most though and it's a nice smooth curve.
not sure on exact dimensions yet but i think it will be a little taller and skinnier, maybe 38inches tall and 14inches wide.
the room is 15ft wide, 25ft long with 9ft ceilings.
do you see an problem with booming bass with that enclosure and tuning?
