Anyone try stuffing their ports?

"I've been cooped up too long. I read 'tried stuffing your port" and expected an entirely different discussion."

Don't be ashamed steve59. We all like different things...  

I do not understand the idea of manufacturers or reviewers suggesting that ports should be stuffed with plugs if the end user is having problems with the bass. After all. speakers that are sealed boxes were designed to be sealed, and speakers that are ported were designed to be ported, so how is it not wrong to change that by stuffing the ports? 

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?
