Hello, all

I  am  considering  employment  of the Tecsound mem-
brane:

   http://www.texsa.com/en/pl39/productos/id62/tecsound.htm

to the internal surface of my  loudspeaker  cabinets
to reduce panel resonances.  Whereas the membrane is
expensive and a whole roll is too much for  my  pur-
poses, I think of buying the Tecsound tape, which is
the same material but supplied in the form of  5  cm
(2") tape:

so I shall have to apply several parallel stripes of
tape to each panel to cover it. Do  you  think  that
will  provide the same level of vibration damping as
a solid rectangular piece of the same membrane:

+---------------+      +---------------+
|               |      |               |
|               |      +---------------+
|               |      |               |
|               |  vs. +---------------+
|               |      |               |
|               |      +---------------+
|               |      |               |
|               |      +---------------+
|               |      |               |
+---------------+      +---------------+

I have chosen the  transversal  orientation  because
the curvature of a panel with a fixed perimeter will
be higher in this direction.
