Legacy Focus plug rear ports?

I make speakers that have multiple pluggable rear-facing ports, so imo plugging ports is a viable means of improving loudspeaker/room interaction in the bass region.

Plugging some of the ports will lower the port tuning frequency, causing the low end to start rolling off higher up, but the rolloff will be more gradual, so in a situation like yours this is imo well worth trying. And you don’t necessarily need to plug the same number of ports on each speaker: If one of them is in or near a corner, and the other is well away from its nearest corner, you might want to plug more ports on the one nearest its corner.

Plugging all of the ports results in a sealed box (duh!), and usually a non-optimum one, BUT if you’re getting excessive boundary reinforcement and/or using a high-output-impedance tube amp, this may give the best results.

Also, while it might "sound fine" initially, I wondered if I'm doing anything sinful and detrimental to the overall engineering of the speaker... or is it just a matter of taste?  

Anyone else tried plugging the ports in the back?  I know a lot of rear ported speakers come with foam plugs. Yes I could try it, but lugging them upstairs will be quite a task so I'd like to hear some opinions before making this move.

I once owned the Legacy Focus. It is a very dynamic speaker.

Usually when a speaker is rear ported it is better not to place it too close to the back wall. Perhaps experiment, move them out 2 feet or more to find that bass sound you want. Then place the Focus feet on some type of gliders that will allow you to move them back and forth when done using them.

You can try plugging the port holes, but I don’t think you will like the sound.
