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
port painted
and now the box felted and complete
any ways, stay tuned will update this next week wit pics and vids of the box swap and of this box installed. and maybe some flex vids also
