Speaker Bass Port Bungs


Does anyone know of a company or manufacturer of bass port bungs for speakers. Or is there way to make your own and if so what material is best to use to control mid bass. Socks are not the answer! Looking for a type of device to use on my rear ported speakers.

I found a set from a pair of Verity Finn Speakers I owned years ago.  What size are the ports on your speakers? 
Does completely blocking a bass port, as in with something solid, change the dynamics of the woofers themselves?

If they are round ports, you might google "expandable test plug".   It's a plumbing part.  That's what I use.

It is all a matter of song selection.
