I just picked up a VMPS "Tallboy" sub off of Ebay. When was this monster made? It's a really great looking and sounding sub. I was told that it has a special acoustic coating on the inside, it has a black cloth/matt material on the outside, and has the standard woofers. What upgrades can you guys recommend? Are the Mega-woofers a big improvement? I like the appearance of the two woofers, so I don't want to go with the new 15" single. Was there originally a speaker cover for this sub? The woofers aren't covered now, except with two plastic grills that the previous owner put there to protect them. Anybody got any original literature on this model? When did they stop making this model? I'm new to this forum. This is my first VMPS speaker. Thanks, in advance, for all your help.
