well after metering (145.3 at 48hz) the last box which was 5.4cubes wit 4 4" ports tuned to 33hz. it does good and sounds great also. i just felt like the small box and the ports were holding the obsidians back some and they had more in em so i went back to the drawing board and came up wit a design i liked, which is 6.2cubes and 101sqin of port tuned to 35hz. hopin the combo of larger box and larger port gets me a gain on the meter. well here are the pics. none really of the box being built, but pics of it built and then felted.
all port edges rounded ova
