Anyone try stuffing their ports?

I used foam thats used for insulating water pipe , rolled up several layers till it was the right diameter . After much trial and error ended up with just one of these tuners in the speaker thats in a corner . The room is not symetrical . It was worth the effort .

Just checking out your system, and on 11/14 you were really excited. So what happened? Sometimes, a change that initially sounds better will sound inferior after a period of time. Sometimes one change begets another. You could try re-positioning the speakers or try some different interconnects, or go back to your old tubes.

I don't think stuffing the ports of a speaker designed as a ported speaker with whatever material comes to hand or has received someones personal rave will accomplish anything musically satisfying.

Response to the "leave it as designed" argument. Simply make a list of the designer's problems:
1. Which shape, size and furnishings in the room?
2. Used with what equipment?
3. How close will actual production be to my specs?
4. What safety factors must I provide so that abusive idiots will not return the item and reduce profits thereby putting me out of a job??
5. What will the reviewers say?
Compare these with my problem of simply how to make it sound best to me in my room with my stuff.
My experience has been that the best sound is achieved either when a good dealer does the whole setup, or when the consumer tries every suggestion that does not result in personal injury.

Rhljazz - Overall I am very satisfied with the improvements the NOS tubes have provided - they are NOT coming out. However, they do seem to provide deeper and bigger bass so am wondering if this is causing any issues with my drivers (only 6.5" poly) as I think mid bass is sounding slightly distorted now - not exactly positive as have not had enough time lately to properly evaluate. Since I have a pair of powered subs, which never break a sweat as they are rolled in very low freq., am curious what it might sound like if they were given a more prominent role in the mix. Which I intend on trying just for fun and thought one way to do this would be to stuff the ports and raise the x-over. But I certainly do not want to mess up the mid freqs. the mains supply, or the speaker's ability to image well. Thought I'd get some input prior to trying (I am not a tinkerer so prefer to have only a few options to try rather than running the gamut myself.)

I would have first tried pulling them further out into the room to see how that affected, but they are already pulled as far out as they can be so this is not an option.
