[Vintage-Audio] Update On AR-4 Info

Mon Jul 7 19:16:11 2003

There are at least two ways the grill material covering was held in place.
Another version used four long and narrow staples through the grill material,
through the wood and then blunted. The grill material was stapled down from the
back side with flat staples on the corners where the material was folded over. I
know of this being done on the AR-4xa.	

The other method is the one that I described earlier.

I now remember.  Yes, this is the way the AR speakers were put together.
There were long, narrow  staples holding the grill in place.  That is
factory, Duane.
As you know, but I itereate, for those reading who may not know, the
polarity is not necessarily important, as long as both speakers are the
same, and hooked up the same, to keep them in phase. We are dealing with
alternating current here, but they both need to putting the oooom in the
oooom pah pah at the same time in the same direction.   In later years, when
replacing the components, most shops would put velcro on the grilles to
re-mount them.  Cheers, y'all .. Mark
