re-attaching Bose 901 VI rear grill?

[skyfly]

Does anyone know how to re-attach the gill on the rear (the V shaped side) of 901 VI?

I detached one corner of the grill just by pulling, but it does not re-attach. The corner of the grill is now loose.

My parents have been using 901 VI for many years, and I wanted to see whether the foam surrounds on the drive units are still in good condition.

Suggest using double sided velcro in each corner.  One piece on the grill and the other on the speaker

That's a good idea. I tried Scotch ordinary strength double sided foam tape that was readily available locally.

Left side is was successful, but the top of the right side came off after one day.

Since the area is small(17mm X 17mm), the wasn't enough bonding power.

I'll second the vote from @BobMac.  The heavy velcro seems to do the trick from what I've seen.
