Subwoofer Box Holder Remix

Imported and resized for speaker holes for 48mm (speaker OD is 50mm so left a lip and some slop/tolerance) converted the resultant .stl to .stp with freecad, imported to 123D and smoothed the internals and double double checked the speaker hole size)

Going to try and get these speakers
or these
Or these

Haven't printed yet..but I think this should work ok, will have to glue the lid on (will try to make another variant where magnets can be put in, but gluing will be best I believe

If you print some please let me know how it worked, remember to put some polyfill in there for lower frequencies

There was not calculation for volume or efficiency or anything..just took original and scaled it for those small 50mm 3W speakers
