Today I got my bunch of $.49 full rangers from PE.

I made leads for them and put a pair in a box for breakin.

The box is stuffed with the stuffing I have around here...
fairly tight, but not too tight to tape the boz closed.

Sitting about 8 feet away those 2 fifty centers in a
completely closed box are decent enough to listen to.
Decent enough for talk radio and blues anyway.

I have a speaker switch to 'get out of the box'
when I want to.

Must be because the cardboard box is thin that the sound
coming through all that is listenable. Seems funny though.
