I would be making a custom cabinet out of 3/4 cabinet grade oak ply which I already have on hand. With the exception of the beat up one, my other speakers are well taken care of light oak cabinets and I would like to match it to them but that is kind of secondary.
As far as the other speaker I assume you mean my other 2.5. I would be trying to find another and placing them as wide/rear channels on stands. I really like the sound of KGs and would like to have a closely match system in a 5.1 configuration.
