Anyone try stuffing their ports?

Years ago I read of someone using plastic straws bundeled and inserted into the port. This seams like an interesting middle road to try. I assume that the straws were cut to the same legnth as the port tube.

I have used plastic drinking straws to fill the ports similar to a method used by Meridian and then ProAc.

Using plastic straws on my Mirage M3's changed nothing until there was a sustained bass note like a pipe organ, for example. The straws then prevented the woofer from oscillating. The improvement in such cases is dramatic. The Reference Recording "Star of Wonder" has such a sustained bass at the beginning of the "Nativity Carol".

I have always been suspicious of port stuffing as a technically valid solution. If a speaker was designed to operate with a port, how can it be correct to plug the port, thereby making it a virtually sealed box?
