round bass traps

[braden_]

I've basically been planning on using 4" of rigid fiberglass from floor to ceiling in the corners, which seems to be the most practiced, but i've found some stuff about cylindrical bass traps. Does anyone know if there are any pros and cons to making some like these?

there's also an article I've seen building them out of plastic garbage cans with Roxul webbed inside. If anyone could sway me one way or the other so I don't have to question myself that would be much apprec'd. =)

There's no advantage to a round shape. Generally, a round trap needs to be very large to get enough usable surface area. So a 20-inch diameter tube trap can do a good job, but smaller types like 9 to 12 inches in diameter are much less effective than a 2 by 4 foot panel.
