small ventilation assembly...suppliers?

Archived from groups: rec.audio.pro (More info?)

hello,

i'm finishing my iso booth this month (got put on hold for a while).
is there a pre-made vent system you can buy? for example, the vent
system on the ones at vocalbooth.com have a rectangular external metal
enclosure that runs up the side of the booth.

i bought some fans and vents that are quiet and should work, and there
is a sheet-metal fabricator down the street from me. so i can probably
pull this off myself.

but if there is some sort of pre-made thing i'd be interested in
knowing.

thanks for any insights.
