HTM-200 in columns - alternatives

[dc_pilgrim]

I am in the process of building a theater. I have a set of HTM-200's that I will put in columns, and I am debating how to use them.

Option #1 - wrap the columns in dazian expocloth (generally considered AT), and add access to the side opening, probably via a fabric covered frame or insert.

Option # 2 - perforated metal there is an e-bay auction (#130146393064) that lists perforated aluminum with the following characteristics:

1/16" THICK
½" Diameter Holes
Spaced on approx. 11/16" staggered centers
48% Open Area

Do you think that this perforated aluminum would adversely affect the HTM-200's?

This is what the column I am working with now.

I would stick with an acoustically transparent cloth of some kind - I think the most common for these applications is GOM but I know it's kinda pricey.

Probably the safer bet Chas. The rigidity of the perf metal is somewhat appealing from a flexibility of install perspective. But not if it is particularly adverse. Dazian expocloth is a cheaper variant of GOM.

You should email Dave F. I'm sure he could give you the definitive answer on the perf aluminum.
